Fix an electric box thingy?

[Anonymous No.1579314]

First of all, Im indeed a retard so you dont have to bother telling me how dumb I am.

So I live in a shitty old house that belonged to my great aunt. Yesterday I heard some weird electrical noises and few hours later some of the appliances stopped working. I narrowed down the problem to this thing on pic related. I removed the case which was slightly burned.

Is there anyway for someone with no knowledge to fix this, at least temporarily, without calling an electrician? Im really poor so at the moment its not something I can really afford.

Help please?

What country? It looks like a terminal block that has gotten crusty. Shut off the power, pull the thing apart, clean it and replace the block if it is damaged. You will also need to cut the wires back to good metal if they are damaged. Put it back together properly and make sure nothing is exposed.

1. MAKE SURE THERE IS NO POWER running through those wires ( there must be a fuse box or something like that in your house )

2. get some wire connectors and replace the old one, cut of the burnt part of those wires first.

3 turn on power again. Done

also WTF do you live? that installation looks like a giant fcking hack! A fuse should have broken that circuit waaay before that happend. Idk if i showed something like that to an electrician where i live he'd be required to shut everything down and and force me to get a certified electrician to do a whole new installation. btw did you idk plug in 3 electric heaters or something like that into an outlet or did it just happen?

also: REPLACE THAT BLOCK do NOT reuse okay? there is no way a certified electrician did that installation btw

Fuses don't blow from arcing. Most melted wires I have seen are from arcing and not over current.

Shut off the power, strip wires and twist them together.
Twist is much better, than terminal blocks.

I live in shithole village in portugal. Yeah I think the wiring was done by my great uncle who was by no means an electrician.

>btw did you idk plug in 3 electric heaters or something like that into an outlet or did it just happen?
Not really. The two things that were connected to it were a washing machine I turn on like once a week and a small fridge. There's two other boxes like this before it reaches those two outlets but they seem fine. It all worked well for over an year since I moved here. When I end up fixing it should I not use the fridge and washer at the same time?

Also, on that copper(?) bar in the middle, below each screw there's hole the cables run through. Instead of replacing the entire thing cant I temporarily put the cables through the two at the bottom that are unused? And what if once I remove the damaged part of the wire there's not enough left to connect it?

Get Wago terminals. 222 or whatever new with levers.
Clean oxide from wire and there you go

Yes you can use those 2. You live in a shit hole anyways, keep up with the tradition of doing nothing right then blaming America when it all burns to the ground.

Would it kill you cunts to just use full wire runs?

>ferrules
unecessary for majority of wiring because cores are solid not stranded
>terminal blocks
yes these are good, they are in the list its those white things next to the twisty red thing.

looks stranded in OP's pic to me but it's hard to tell with all the molten plastic

Probably PN, can be used without bootlace ferrules.

The other on is RK which has finer and multiple strands and should be used with bootlace ferrules, commonly used in automation control panels.

rather than switching the wires consider switching your house

GORETEIM!
OP, thats a fucking bonfire waiting to happen. You need to rewire that fucking place, before the problem sorts itself, and sorts you with it. That shits all chickenwire from 1920's or some fucking thing, its not designed to carry large currents, and age obv. aint improved it much any either. Someone obviously had a go at improvement already and added the earth, just, get rid of the rest of that 2-core white shit now, its junk.

Saw your pic, reminded me of village wiring in Portugal I saw a kid visiting avo; then I saw this post. Feels good.

[Anonymous No.1583101]

Get wire of the right gauge/color
Get wire nuts
Get wire stripper
Fi d an equivalent block

Turn off power
Splice
Terminate correctly...look at YouTube
Turn back on

[Anonymous No.1583609]

>>1579314
Turn off the power, cut and strip both wire beyond burn point and splice them back together. What you're seeing is the result of too much amperage being pulled relative to the design of the wire. Something power intensive is overloading this and probably just going to happen again if you keep running it threw that circuit.

Not with solid core. And stranded, with which that is possible, shouldn't be used at all in fixed installations.

>>1579426

This. And replace the wiring with proper 3 wire cabling (with ground) while you're at it.

In his case, best option is Wago with grease.
Second best is thirdworld joint (pic related).

Really...The top wire failed because it was not secured tightly enough to the terminal screws. The green color is from being overheated and loose.The fix I would use is to cut off the green part and plastic insulation on both the left and right wires and use one of the 2 unused bottom connectors to make the thing work again. That is a 4 connector terminal block with only 2 in use. Make sure the wires are cleaned down to the bright copper and that the connections are screwed down very snug and tight. The wire failed at the top from a weak wristed electrician.

2. Cut and clean the burnt green wires to bare copper and wire nut the fuckers tightly back together again. Make sure the power is off. I work on live shit all my life but know what I am doing

WRONG....wire has failed because of weak connections at terminal block. I have seen this a thousand times. If the wire were under sized it would burn all the way back to the fuse box, breaker box. Note how the screw fitting into the terminal block is melted. It is a classic shit connection. Guys that are wimps make those weak connections all the time and they always fail. I suspect some guys do it on purpose to get chargeable call backs a few years latter.

You're both right but missing the root of the problem. Look at the corrosion on the connector. That is what is causing the connection to lose proper contact and create resistance in that connection. Resistance + current = heat. So the question is how is this connection getting enough water on it to corrode like that?

I ran it in conduit in my garage. At 95 °C, you can get a decent conduit full percentage and still get 20 amps per conductor.
