I've stumbled upon this when connecting PV installation at some old house.

>>1585701
i've seen this shit before as well, once came to rewire a light, standard socket, nothing difficult, accessed through attic, textbook ... but multiple different coloured wires were connected to the same point on this light socket including earth, live and neutral colourations from 3 different standards.
i also love it when people use yellow/green earth wires for power in the same socket in which other yellow/green earth wires are acctually used for earthing.

>>1585701
yikes!

>>1585701
nothing wrong with that
if no one touch it there is no reason it will move and produce any harm

>>1588307
*spits*

Hand me them there dikes, boy.

>>1588307
fill the can with hot tar, it'll be good for a century.

>>1585701
at some point this will have probably had a wire nut on it then some cunt has come along without a clue and taped it up.
colour combos are interesting, where is this installation?
its only the top feed that is new and the cpc connected to neutral. the ground of course is probably carried by the steel conduit/box and with nowhere obvious to bond to...
of course it is perfectly possible that an upstream protective device is protecting the white cable and so there is no issue at a technical level with this installation.
the rules were different in the old days, there were no tests or inspections either so nobody cared.
things like this were a necessary part of electrical safety evolution, without things like this we would never have learned it could be dangerous.

previous contractors left the lights and the heater above the ceiling grid.

Had me giggling like a retard because this is what my j-man is like in a nutshell

Rats chewing through a 3 phase supply cable

Supplier sent my work 20 boards and 80% didn't work. Traced it down to incomplete cut track modifications. Lazy technicians.

Not so much electrical but a small snake chilling on top of some aeronautical radios on a job lol.

>>1592276
>>1592277
What causes this

>>1585701
from what post soviet country are you?

>>1592288
there should be a huge contact surface between the two pieces of metal.
for whatever reason the contact surface is not contacting well enough to give a low impedance path for current to flow.
the current is presumably flowing via nut and screw instead of directly between the plates.
possibly the increased impedance is due to e.g. oxide layer forming on metal wasn't cleaned properly or surface finish problems/something stuck between when tightening means bad contact or maybe there a sticker or peelable protective layer that just wasn't removed.

current flowing through the relatively small nut causes heating (all current causes heating).

>>1592288
The nut is glowing to warn you that the power is on. It is a safety feature developed by the soviets

>>1592276
>>1592277
>>1592336

usually this is caused by way under tightening.. though its been known to happen with over tightening too

>>1592273
Haha hilarius. Have a bump, funny thread

Went to replace some old fluorescent light fixtures in an older storefront one time, the light fixtures were installed / wired back in the 70's I think. This is in a small town and there were only a handful of electricians around back then. The guy who installed the lights was a bastard and chained the light fixtures together using different colored wires each time he jumped from one fixture to the next. My dad knew who he was and said that he did stuff like that all over town because none of the other electricians in town would follow up on anything he had wired so the property owners would have to call him back to do any future work. Well he died in the 80's and workers around town have been dealing with his bullshit ever since then.

It looks like the trace was meant to be severed and connected elsewhere via that jumper wire. The trace is still partially intact.

you mean the classic "leads going off picture" pic?

>>1593178
Should have been connected to itself

>>1593178

I do this all the time and there's nothing wrong with it so long as it's grounded and on a GCFI.

I do it because mom won't let me open shit up or turn circuits off for splicing, so I got to draw from somewhere. As a result all the new electronics in her house, powered by new outlets, are all on the same circuit despite being in different rooms.

One of the houses I refurb'd back in the crash had been owned by an electrician from one of the nearby auto plants. He'd rewired most of the house over the 30 years he'd lived there, adding lights & outlets everywhere.

You couldn't trust anything, wire color, gauge, circuit, nothing. I'd flip a breaker, verify the outlet was dead, then pop another breaker cutting the wire because he was using the bare wire to power another circuit. What a trainwreck.

OC from yesterday.
Classic sparky hack.
Pool filter motor had external ground
And he didn't want to run a new ground so he put the motor's ground (white wire coming in on bottom left) through the box punshout and connected it to the bus bar...
No problems could have happened there.
Also, knife switch had the insulated hook piece broke so you couldn't disconnect the fuse...

>>1594714
Its a pressure sensor (-1 to 1bar) someone was welding with a tig and slipped and hit it.
Only showed 1bar after it, or 20mA.

>>1592830
Live in a small town where shit like this happens. Not just wiring, but with all different shit. Will post a few stories in a bit.

Ok story time.

Have an old friend that owns a computer shop that looks like shit. A lot of nigger rigging. His work area has two power strips that are plugged into two (outside use) extension cords. Since there are no outlets by his work area his dad drilled holes into the floor and ran the two cords into the basement where they are plugged into one outlet. The holes were not big enough so the cords were spliced and pushed into the holes and put back together.

The bathroom in the business has no heating and only one outlet that is built into the light socket. His dad used a normal computer power cable (C13 style) as an extension cord. He jammed the heaters power plug into the end of the computer power cable.

Since I am ragging on this fucker. Let me tell you about his soft serve ice cream machine. This fucker thought he could make some extra money selling Dole Whip type of ice cream because he says it sells well in Disney World when he goes there every year. Again his dad setup the machine and get it inspected before they could sell any ice cream from his computer shop. Well they failed because his dad used a garden hose to supply water to the machine.

>>1595882
A B S O L U T E L E G E N D
I love seeing this shit, not because it's so bad, but because some GROWN MAN said to himself "yea, this is good enough. This will work. I see no problem with what I've done. No way will this cause problems"
Like I cannot fathom how an adult can do this shit and think nothing of it. Shit cracks me up

Hop this isn't off topic. Just bought an old house that is extended at the back and the previous owner seems to have done electrics himself. Some parts are a bit black (inlcuding a socket), but it looks like that happened long ago. How worried should i be? Does it need changing asap? We are on 110v btw, if that makes a difference..

>>1593264

absolutely haram and capitalist

>>1592830
>>1595882

I have one as well.

One of my moms friends bought a house built in the 80's by a Electrical Engineer who worked for GM. He designed and built it himself working as his own GC.

Big house, in ground pool, home theater, the works.

Anyway, he died, moms friend bought it, goes in to start remodeling to update... behind the sheetrock every single wire in the house is orange extension cable.
You know, like the 50' or 100' orange contractor extension cable?
From the load panel, to every switch and outlet, was orange low gauge extension wire.
The oven and the pool heater were on the same circuit, fed by MASSIVE idk what gauge aluminum cable.

None of the electrical companies wanted to take on the job without her putting up a $500,000 liability bond.

Well, she didn't do that, found Cletus and his pickup truck 'electrician' ... and mid way through the remodel, the house burned to the ground.
Caused by? Electrical Fire.

Another 'Engineer Fail' in town is his wife inherited a huge ornate 1870's farm house (the kind people are now paying over $1,000,000 to get), with 1950's era surface mounted wiring. Story is that barely a week after they had the title engineer husband decided to go in and start doing 'updates' by himself and started an electrical fire right next to the oil heating boiler.
By the time the Fire Department got out there the place was more fire than house.

Engineers are stupid dangerous MFers.

Shill pls go.

>>1594732
same here, bought a house from an electrician. I'm scared to mess with any of the wiring.

He had a half gazebo built around a 1970's in ground spa. The spa didn't work, when we had our breaker box upgraded because we were having Air conditioning installed the spa just suddenly started working. When I tore down the gazebo so I could poor the foundation for a back patio I found out that the wiring I removed from it was also powering my shed on the other side of the yard. Cost me $2500 to get that fixed. There's a 30 amp breaker on the back room of the house, which I think was also powering the shed.

Now my shed has a proper 125 amp sub panel.

Kitchen, den and parts of the living room were all on one circuit, so I could not run the toaster, electric oven, or microwave and anything else at the same time. I had a separate circuit installed in the den for my computer equipment, and 2 separate circuits in the kitchen for the microwave and electric oven.

The house I grew up in had 2 20 amp fuses for the whole house. one fuse was always blowing. when my dad paid for a new breaker box they found that everything in the house was run through only one of those fuses.

And it stayed like this as is not my business to rewire the entire house

>>1596904
My parents house was a cluster fuck. Electrical to plumbing.
Wiring going to boxes that are not connected to anything or wiring coming out of a box with the end of the wire taped off. Boxes daisy chained from one side to the other. New circuit breaker panel and wiring that leads to the basement that is wired into old wiring which is wired into older wiring. Rooms sharing the same circuit in some parts of the house.

The plumbing wasnt any better. PVC (or CPVC) in 1 foot lengths connected together to make one long run. With copper tubing mixed in and black hosing. My dad and bother "redid" the pluming but just fixed want needed fixing or half ass the shit.

My brother thought it was a good idea to rip out the bathroom upstairs while he was working on it he ran out of drywall so he used cardboard to finish a small area (1 - 1 1/2 foot by 1 foot area). Then goes on to use duct tape to seal the edges, slaps a few nails into it, and paints it.

>>1596803
The problem with crispy wire is that some bloke overloaded the line. Depending on the wire that will harden the insulation or flatly start to melt the conductors. Best to replace it and trace the wire from outlet to breaker just to be sure nothing else is buggered.

>>1597049
aaaaaaaaaaaaaa

>>1596803
>Hop this isn't off topic.
it's exactly what the thread is about
>How worried should i be?
7/10 goncerns
>Does it need changing asap?
yes

>>1593178
>all upside down
>top of the ground hole will be cracked inside a month of use
lol

>>1597210
Some places require the outlets to be installed like that per city building code. I know that for a long time Dallas and Fort Worth, two major cities in the same metro area, had opposite code requirements for this. One of the cities required the ground hole to be on the bottom and the other required the outlets to be flipped and installed so that the ground hole was at the top.

>>1597210
the outlets in the honeywell plant here are all upside down. supposedly so that if a plug isn't in all the way and something falls on it, it won't short across the blades.

>>1597217
>>1597221
Every office I've ever been in where there's a cleaning crew and where the outlets had the ground at the top had the plastic above the ground hold broken. It is caused by people pulling up as they unplug. when it is flipped that action doesn't break it. The same problem also breaks the ground plug. The biggest problem is that people are fucktards and can't unplug something using the thick part of the plug nor pull it straight out.

It looks a bit like this, but not as bad usually.

>>1594714
Usually a sensor will show at max value when it's proper fucked.

>>1597227
Yeah, I know what you mean and I've seen it several times too, I was just explaining why someone would install them upside down like that and how it might be legally mandated and not up to personal preference. I was told that the argument for mounting the outlets with the ground hole on top is that if a plug is partially pulled out of the outlet but still powered then it can be a fire / electrocution hazard if something metal should just happen to perfectly fall and land on the hot prongs and bridge the load and neutral prongs. If the ground pole is up then there is even less danger of that already unlikely situation resulting in a fire or shock.

>>1585701
Yes. That is perfect.

>>1589401
I will never live somewhere that isn't a freezing hell hole for 4 months a year for this very reason.

>>1597302
So where is a soldered lineman's splice on that tier list?

>>1597302
>bonus points for not using pliers
Mmmmmmmwhy

>>1597332
Be real here bro. This is shit that a tradesman has to bang together as fast as possible while drunk, hungover or high. Doing a soldered lineman's splice would be like asking a drunk chimp to thread a needle while wearing a pair of catchers mitts and a blindfold.

>>1597371
You get a more even twist with better contact by using pliers.

>>1597378
>You get a more even twist with better contact by using pliers.
Exactly, so why bonus points for not using pliers

>>1597387
The image is an ironic joke. All the bonus points are for doing things wrong, and the progression from god tier to shit tier shows progressively better forms of connecting wires.

>>1597217
There's a good reason for mounting them "upside down", but what the fuck would you require people to mount them smiley-face for?

fuck you guys
this shit is comfy

I just did this like 10 minutes ago

Here' an update

>>1592830
HAHA fuck me dead

>>1598009
where would this be I wonder?
>>1592273

this is currently existing in a wall cord behind forniture in my room and I'm ok with it

>>1597805
I'm fascinated: what country do you think that might be okay?

>>1598137
Somalia

How the fuck does a GFCI breaker without a hot connection sense this?

>>1598137
lets try it the other way
you tell me specifically what about it that is visible from that picture that you can say for certain would contravene a regulation of your country.

>>1598389
>you tell me specifically what about it that is visible from that picture that you can say for certain would contravene a regulation of your country.

The PVC tape at the joint.

>>1598365
Dumbass here, what am I looking at

>>1598424

It seems that he has outlets that are not powered and yet he has GFCI questions about them.

>>1598365
All GFCI's work the same way. They measure the current going in to the circuit through the hot, the current returning through the neutral and trip if those values are not within a preset range from each other.

>>1598431
Is that even a GFCI though? I dont see the test/reset buttons. Or do not all GFCIs have that feature

>>1598437
It's not a GFCI receptacle. He said GFCI breaker.

>>1598445

He also said the breaker was not connected to hot, and the rest of his retarded post implies that that breaker supplies this outlet, meaning this outlet has no power.

Unless he has a GFCI breaker that is not hooked up and he thinks it magically protects outlets that get power from other breakers.

Maybe he's a gifted troll, but I'm thinking yet another idiot who has no business dealing with electricity.

>>1598447
And I think you care too much about it. I'll just answer the questions, you can worry about intent.

>>1598409
And what rule or regulation does that contravene?
Bearing in mind that you dont know what method of connection is used under the tape of course...

>>1597768
>takes pictures on his phone for cause of death
nice

>>1597127
>>1597151
Thanks for the replies. If anyone know the answers to more questions, I would be very grateful.

Does it being 110v, instead of 220v (I am from Europe), make it less likely to cause a house fire?

If I don't plug much in at that part of the house (its a sort of extension at the back, with electrics running off from the main house) and use it minimally reduce the risk of it going up in flames?

Reason I am asking is because I am very poor after spending all my money on the house and can't really afford pro eletrician at the minute, plus there are several other pressing concerns, like walls and floors, as well as the electricity pole itself (wooden and might fall over soon), so I its difficult to get it done asap...

Here is another pic, notice that there is really uneven discoloration and also some darkened parts away from the wiring. Really not sure what happened there, its not like that whole of the eletrics is as bad as that spot..

>>1598543
>wood is charred from the wires resting on it

Absolutely terrifying, would unplug.

>>1598543
The wire going away from the camera in the picture has gotten so hot it's cooked the wood.

Check the gauge of the wire and then the breaker/fuse protecting it. I'm willing to bet the breaker or fuse is not sized correctly. Even if it is I'd replace it as it's obviously not functioning.

Also Id replace that run of wire as far as possible. Even if it's just cutting out the burnt part. The inner insulation is cooked and will be compromised.

>>1598543
Whew lad, that picture. You people give us shit for the way some of our shitpiles are built but god damn. Please tell me that is a barn or an outbuilding or something and not someplace people live.

>>1598577
Its an extension to the main house. Its built like a shed, we only use it on warm days. I wanna redo the walls, insulate against the roof and take off the shitty ceiling that this picture was taken on top off from. I want to rewire the lot for that, but don't really wanna do it until I am ready for the whole project, as I want the wiring to be moved for that too.

We lived in this house for 10 years now, it was like that when we got here, but never really took it seriously until we now bought it. Wires are maybe not as bad as they look. Still flexible, don't seem charred, just darkened and must overheated at some point in time, probably long ago. Likely because this plug socket got wet from the outside or something (we had ants coming out of it) once and also got a bit blackened..

>>1598475
>Bearing in mind that you dont know what method of connection is used under the tape of course...

But I do: it's clearly not wirenuts, screw terminals or Wago's, which are the only connecting methods allowed here. In addition, even if it was using one of those three methods, you can not put PVC tape on the connector (and are discouraged from putting PVC tape on the wires) because PVC tape can fall off, over time.

I get that you're in some third world country where they've just discovered fire, let alone this new-fangled electricity thing, so you might think that huehue job looks just fine. Enjoy your housefires.

>>1598641
As long as it's twisted properly you get better connection than any other way. Some tryhards even solder over it.
Code isn't word of God, it's just a way to minimize the chances of retards fucking shit up. Unless it's a stranded wire that's barely touching the other wire this shit is solid.
Fucking soiboys afraid of going against regulations and electricians pretending that their job isn't dead easy.

>>1598678
>Fucking soiboys afraid of going against regulations and electricians pretending that their job isn't dead easy.

Okay. Enjoy your housefire Ranjit.

>>1598698
I see I struck a nerve.
I will enjoy my superior low resistance, thank you very much. Wago is WAY more likely to cause a housefire.

>>1598704
>too poor to afford wire nuts

>>1598710
The fuck are you smoking, that would be a level of poverty where I wouldn't be able to waste time on 4chins or even get an Internet connection.

>>1598641
Where do you live that soldering or crimping is not an accepted method of connection?
You don't know that there isn't heatshrink under the tape.
I agree tape is horrible but not expressly forbidden.

The point is you can't inspect from your chair you have to actually check what's going on.

You don't know where I live I would suggest you shut up because you clearly don't know what you are taking about and just embarrassing yourself.

>>1598716
>Where do you live that soldering or crimping is not an accepted method of connection?

A 1st world country.

>You don't know that there isn't heatshrink under the tape.

Also not permitted, in any case.

>>1598424
A ground wire touching the neutral side of an outlet.

>>1598431
I disconnected the hot upstream as part of troubleshooting.

>>1598433
If there is no hot connected, how the fuck can it trip GFCI?

>>1598437
Is connected to a GFCI breaker.

>>1598447
I disconnected the hot because it was tripping, as part of isolating/troubleshooting. Even with ONLY a neutral and ground connected, it is tripping (due to this contact between neutral and ground in the pictured outlet box).

>>1598717
haha ok guy sure thing
how did you get here, by accident?
do you want some crayons or something instead?

>>1598833
The neutral from upstream is still connected. It flows to the neutral at any load you have and a tiny amount of current t goes through the neutral and follows the neutral up to where its touching ground, then some current leaks to ground and trips the breaker

>>1598889
Neutral and ground connect to each other on the ground bus.... The neutral passes through the GFCI breaker ostensibly for current monitoring and comparison to the current on the hot. But.... There can't BE any current flowing from neutral to ground... It is just a big fuxking loop... Right? I can't detect any on my MM when I jump neutral and ground (though the breaker still blows about a second later). Not even a voltage diff...

>>1598833
I already explained it to you. The hot doesn't need to be connected to trip a gfci breaker. The breaker measures both line and neutral wires. Move that plug's neutral off the gfci breaker.

>>1598922
What and how can it be sensing from a single point on an incomplete circuit?

>>1598934
The neutral of a circuit runs through the GFCI breaker. Disconnecting the hot will still leave that connection. ANY leakage in that wire will trip the breaker.

The neutral goes on and (probably) connects to other things. At some point it might have a bond to ground, or cross other live circuit or maybe it's just inducting enough EM to trip the GFCI sense.

I've been called to replace GFCI/ARC breakers that trip when a HAM next door keys up. That's how sensitive they can be.

>>1598916
The gfci can trip in something like 20ms from a 20ma leak. Youd need an oscilloscope to capture that.

The neutral could pick up current from anywhere else and a tiny bit would go to ground.

>>1598991
>>1598943
Weird. There is literally nothing else connected to the breaker. It is exactly like in the drawing. If the ground does extend further than the neutral (due to the EMT) however. Man that is voodoo shit.

>>1599010
desu it's (almost) expected behavior. Floating the hot side while the neutral is still connected guarantees the GFCI sees transient spikes on the neutral bus while reading nothing on the hot side.

If you have a non-contact voltage detector hold it up to that neutral wire and watch it light up. That wire is sinking current through the GFCI and GFCI's aren't suppose to tolerate any current flowing the wrong way.

>>1598009
Where can you find standed alu? Do they even exist? In soviet russia I never heard of them.
Anyway, solid alu is shit, fragile piece of shit. I decided to upgrade a socket, ended up replacing all shit with copper.

Retard here, why not just remove all the electric wiring and re-do from the beginning?

>>1600602
Because that takes time and money (wire isnt cheap). You have to yank all the old wiring out then re-pull new wiring in back to the panel.

https://en.wikipedia.org/wiki/Aluminum_building_wiring#Aluminum_wiring_in_modern_building_construction

>Aluminum building wiring for modern construction is manufactured with the newer AA-8000 series aluminum alloy (sometimes referred to as "new technology" aluminum wiring) as specified by the industry standards such as the National Electrical Code (NEC) for wiring within a building. The use of larger gauge stranded aluminum wire (larger than #8 AWG) is fairly common in much of North America for modern residential construction. Aluminum wire is used in residential applications for lower voltage service feeders from the utility to the building. This is installed with materials and methods as specified by the local electrical utility companies. Also, larger aluminum stranded building wire made with the newer AA-8000 series alloy of aluminum is commonly used for electrical services (e.g. service entrance conductors from the utility connection to the service breaker panel) and for larger branch circuits with higher loads such as those for sub-panels, ranges, clothes dryers and air-conditioning units as specified by local electrical building codes such as the National Electrical Code (NEC).

>>1600670
>>In North America the use of smaller solid aluminum wires made with newer AA-8000 series aluminum alloy are allowed to be used for lower load 15A or 20A branch circuit wiring within a building according to the National Electrical Code. The terminations need to be rated for aluminum wire, which can be problematic. This is particularly a problem with wire to wire connections made with twist-on connectors. As of 2017 most twist-on connectors for typical smaller branch circuit wire sizes, even those designed to connect copper to aluminum wiring, are not rated for aluminum-to-aluminum connections, with one exception being the Marette #63 or #65 used in Canada but not approved by UL for use in the United States. Also, the size of the aluminum wire needs to be larger compared to copper wire used for the same circuit due to the increased resistance of the aluminum alloys. For example, a 15A branch circuit supplying standard lighting fixtures can be installed with either #14 AWG copper building wire or #12 AWG aluminum building wire according to the NEC. However, smaller solid aluminum branch circuit wiring is almost never used for residential construction in North America.

It's pretty obvious from your picture the cabinet to the left, is unlocked, even if it was since closed, all it takes to unlock it is a flathead screwdriver and some lever action. If that's the fusebox you are golden, it can be opened 90º, if it is the telco's it should be easy enough to dismount.
But that should be a last resort, have them relocate it, because I am pretty certain blocking off the fuses is illegal.

480v won't arc one millimeter.

>>1606212
Not that guy, but:
Arc flashes can happen with high current, low voltage supplies, anon.

One a tiny arc is established (from disconnection) there is practically infinite current carrying capacity. If the current is high enough it can maintain a gap proportional to the current the system can provide.

They won't jump at you though, it would require a sudden disconnection under high current.

You know I can laugh at this and also at myself because I did something similar with the positive terminal on my 86 Toyota Camry. The Positive terminal plate was fused to the factory clamp, and since I couldn't get it off initially I wound up clamping/crimping it onto a new clamp's stem to put on my terminal. Worked perfectly fine for 3 years before I finally had the time and tools to remove/replace it proper. Still remember my dad's reaction when I showed him the jerry-rig: "Yup, I can see you're my son for sure".

>>1612077
what the fuck am I looking at here

this is the fixture I use to plug things together in series.
Made almost 100% from parts taken from abandoned buildings. No i don't have any cover for it.
Those 100 year old switches are pretty nifty because I only ever have to push down on them, so it doesn't slide around the workbench when I'm switching them. and they're rated for DC too

>>1612203
I'm glad you asked. A friend of mine and I designed and built a starter motor for a generator, which automatically starts the generator when a loss of power is detected.
The outlet in the top left is where whichever device you want powered gets plugged in. The two phone chargers take 120v AC inputs from two electrical cords (out of frame), and convert them into 5v DC outputs, which feed into the arduino. When power is lost, the relay (bottom middle) switches the outlet from wall power to generator power, and the arduino activates the second relay (blue black and green thing next to the battery) which sends power to the starter motor. The starter motor then runs in 3 second bursts, until the generator starts. When that happens, the arduino reads that voltage signal and shuts off the starter motor.

Running a lutron system with the boys today. 68 windows, 10 homeruns a panel and two panels for the switches. And that's just the shades
God damn

>>1612292
How do the phone chargers get power to the arduino when the power is out and the generator hasn't yet kicked in? I mean the phone chargers' capacitors will drive the arduino itself for perhaps a few seconds, but they could be empty before the generator is running, and driving the relay itself will be next-to impossible just off filtration capacitor charge.

Y'all wanna see my panel that my grandfather and his two sons ran 20 years ago? Ok granddad been union electrician for 55 years this year. First son is working on 30 and second son is at 25 years union. It was a rush job to make it livable.

>>1612317
One more close up
I'm not licensed yet

>>1612304
The arduino has an independent power supply which isn't hooked up in that picture. The phone chargers don't provide power to anything, they just convert wall voltage to something readable by the arduino.

>>1612317
No 90's huh?
Just a fuck it run it and go. Nice.

you know it doesnt take much more time to make it look a little clean, not talking it has to be on a level of autism as pic related but a half-assed sort of laid out plan going forward is better and less time consuming than what that mess must have been.

>>1612320
>they just convert wall voltage to something readable by the arduino
Ew, just use some diodes and resistors, maybe optocouplers too if you need it to be isolated. Some of those phone chargers shut off when there isn't enough current flowing, or shut off because they're cheap shitty chinese garbage.

>>1612362
>diodes
>resistors
>optocouplers
I should clarify that there were no electrical engineers involved in this project. MEs don't even know what an optocoupler is.

>>1612362
>>1612367
Non sarcastic followup question: why use an optocoupler instead of a rectifier with a capacitor?

>>1612367
MY GUESS IS THEY'RE ALL USING THE SAME BOARD - IF IT WASN'T FOR "POWER TRANSFER," THE BOARD I'M DESCRIBING WOULD HAVE BEEN DESTROYED YEARS AGO. THEY'VE PROBABLY GONE BACK TO THE DRAWING BOARD TO FIGURE OUT WHAT EXACTLY THIS DEVICE DOES - I'M JUST ASSUMING THEY'RE GOING TO NEED IT TO SOLVE SOME OF THOSE PROBLEMS. A COUPLE THINGS CAN HELP IMPROVE THIS PERFORMANCE ISSUE THOUGH:
1. USING MULTIPLE USB DEVICES ON THE CPU

I THINK THE PROBLEM IS LIKELY DUE TO THE DIFFERENT CONNECTIONS ON USB-LIKE DEVICES, WHICH I'M ASSUMING ARE ALL USB DEVICES WHICH DON'T HAVE A BUILT-IN POWER CONTROLLER LIKE THAT INTEL CORE I7. THE USB-TO-FIREWIRE CONNECTION IS MUCH FASTER THAN A USB HUB (WHICH ISN'T WHAT I'M USING). THERE ARE 2 OR 3 REASONS WHY THIS MATTERS FOR BATTERY: THE USB-TO-FIREWIRE CONNECTION MIGHT BE THE FASTEST WAY TO CONNECT TWO OR MORE USB DEVICES ON A BUS AND TRANSFER THE DATA FROM ONE DEVICE TO THE OTHER, WHILE THE USB TO FIREWIRE CONNECTION IS DEFINITELY THE FASTEST WAY TO TRANSFER THE DATA FROM TWO OR MORE DEVICES AT THE SAME TIME.


2. NOT BEING ABLE TO CONTROL ONE USB DEVICE AT A TIME

I SUSPECT THIS ISN'T REALLY A PROBLEM. I HAVE TWO MACBOOK AIRS WHICH I USE TO EDIT AND PERFORM BASIC SOFTWARE TASKS (LIKE RUNNING SOME PROGRAMS). ONE OF THEM HAS AN APPLE THUNDERBOLT 3 CABLE ATTACHED, BECAUSE IT HAD THE LEAST BANDWIDTH FOR USB DRIVES.

3. NOT BEING ABLE TO USE TWO USB PORTS AT ONCE TO CONNECT FILES

THIS ACTUALLY IS A PROBLEM, AS MOST THINGS I NEED TO RUN IN MACOS ARE PRETTY WELL BALANCED BETWEEN USB AND USB 2.0.

4. NOT BEING ABLE TO CONNECT MULTIPLE CABLES TO AN APPLE DOCK

WITH MACOS, YOU CAN CONNECT MULTIPLE USB CHARGERS TO AN APPLE DOCK USING DOCK MODE.

5. NOT BEING ABLE TO USE USB3.1 WITH APPLE KEYBOARDS

APPLE KEYBOARDS CAN ONLY TALK TO 3.1GBPS. AND THAT'S ON A MACBOOK AIR. NOT A SMALL DIFFERENCE IF YOU ONLY OWN ONE OF THEM.

6. NOT BEING ABLE TO USE A USB STORAGE DEVICE

I FIND IT USEFUL AND COMMON TO USE SOME MAC SOFTWARE AS A USB STORAGE DEVICE.

>>1612371
why

>>1612369
If your arduino wants to sit at some strange voltage with respect to neutral (because of its peripherals) such that neither a full-bridge nor single diode rectifier will result in an equivalent 0V rail, an opto might help. Such as the battery charger using some strange step-down topology. Even if that isn't the case (it probably isn't) you may want to use capacitive droppers instead of resistive droppers, which mean you have to use a full-bridge and therefore get a ziggity-zaggity 0V rail with respect to neutral. Having this as the arduino's only reference to ground could mean you could get some noise on your pins if you don't shield the whole thing properly. This also applies if the battery charger circuit uses a full-bridge and you don't want to waste 4 diodes on each mains sensor I guess. I hate full-bridge rectifiers for the above reason, and only use them if I have to make a capacitive dropper circuit. A third reason would be just protecting your circuit from voltage spikes caused by the generator or relay or even external influences like lightning strikes.

Pic related is likely the simplest method to getting this to work properly. Using a 4.7V zener or something along those lines to replace R2 would be a better idea, but you probably don't have one lying about. R1 should be as big as reasonably possible to not waste power, anything from a few hundred kΩ to a few MΩ would work, and R2 should have a value that makes its peak value nearly 5V (170*R1/(R1+R2) = 4.5). The use of a zener or opto would help stop the thing from killing your arduino in the event of a voltage spike, but your entire circuit should be packed to the brim with protection and noise suppression circuitry anyway (MOVs, PTC thermisters, X and Y caps, common-mode and normal-mode suppression chokes, etc) and I doubt you'll bother with those.
Also you better be fucking using interrupts to save battery if it isn't being charged constantly, and you better have a freewheel diode.

>>1585701
I'm just a tourist here to /diy/, thought i'd come looking for some laughs. Boy did this thread provide them.
Some background, I've been in the business of restoration and remodelling of old homes for about 25 years now. I've seen some shit. I was even smart enough to take pictures of some of it.
I am now going to share two of my favorite electrical disaster pictures with you.
They come out of the same house.

This first one is the main line coming into the house, after the meter and before the breaker panel (if there was one, desu I didn't go inside, crawling around underneath was more than enough to tell the owner we didn't want to do the work she wanted done).
Yes, the only thing visibly holding those wires together is about a roll and a half of the old style cloth electrical tape. No box, no clamps, no nothing. Just a scrape and tape splice of the main power hanging around under the porch waiting to kill someone.

>>1616192
There's probably one of those clamps you see on the grounds under all that tape, but who really knows.

If you crawl a little further along under the porch, you get this lovely surprise. I know, the electrical is far from the only thing wrong in this picture, but it's what the thread is about. What you see here is 4 circuits lovingly grafted onto the original knob and tube wiring. And when I say lovingly grafted what I really mean is they scraped some of the insulation away, twisted the wires together, and wrapped some electical tape around the wires.

>>1616199
Nice. Also, that looks like asbestos insulation on that pipe. So, have fun with that too.

>>1616204
Yes, that IS asbestos insulation on that pipe.
I did nothing with it.
I forget what the HO wanted done, but that asbestos was one of the _many_ reasons we didn't do anything on that house.

>>1612382
nigga next time just say "for isolation" and spare the man from having to think

>>1616212
But isolation doesn't explain anything. To know whether or not he needs isolation he needs to understand his circuit. Just telling him to go out and buy some optos when he may or may not need them would do more harm than a wall of text.

>>1593178

I am telling you, that you still have a phone company in your area. Did you use to have Verizon? Its frontier now? Qwest? ItsCenturyLink. Something else? Doesnt matter.
