Wiring a 220V 50A Outlet

[Anonymous No.1067477]

is there any reason i can't put a 220V 50A NEMA 6-50 Outlet directly below ( ~2 feet ) the breaker box in my garage? service comes in behind the panel and all the wiring goes up into the ceiling. i can put the junction box on one of the studs for the breaker box and fish the wires from below. there are 4+ open spots for a 50A breaker.

i'm going to use 6-2 solid copper

this is for a miller thunderbolt 225 ac welder

You can but I'd just as soon bring it up into your attic, come down with EMT and set a metal 4 square box. That way you aren't running cords/working right in front of your panel.

Throw main breaker first. Cut hole for box in wall, use remodeling box. knock plug out of the bottom of the fuse box and push wire into box. Use two 25 amp breakers run white wire to one and the black wire into other breaker and snap both into bus bar. run ground to ground bus bar. . Fish wire through remodel box and install box into wall and wire outlet. take about an hour. Make sure box placement allows a straight shot to fuse box due to wall studs

>Use two 25 amp breakers

dont listen to this nigger unless you want to kill yourself. you need a 50 amp breaker

the fuck is wrong with these fucktards suggesting this shit all the time

OP here
>>1067760
not sure why anyone would do that anyway

so all i need is:
50A double pole breaker ($10)
6-50 Outlet ($10)
outlet plate ($3)
~4 feet of 6-2 solid copper wire ( 2 black, 1 bare ground ) ($8)

what kind of box do those outlets mount in? will any double gang old work?
should i stick with siemens (all the other breakers are siemens) or will any 50a double pole do?

I don't know where you are located but in the USA there are several brands of breakers that aren't interchangeable
If the one you buy is the same style as the Siemens it should work
Personally, for sake of professionalism, I'd put a matching breaker in even if it costs a bit more..

yes by all means only use 1 50 amp breaker also photo shows a water or gas line below panel these can run left to right

Yes, the standard double is what's used. I install these for restaurants.

Are you mounting on the wall or behind the wall? My line for my dryer just comes right out of the box and mounts over the wall. It's in my garage on a cinderblock wall, though. Point being, your panel appears flush, so you're going to end up cutting drywall either way, just mount behind.

Make sure to check any state, county, local, or homeowner association guidelines before you perform any work. Most likely you will have to have a city/county/state residential engineer come and specify particular requirements. You also may have to get a remodeling licence because you are dealing with a utility. Usually after doing some wiring has been done it is illegal to install a breaker until it is inspected and signed off by the appropriate authorities. As for brand of breaker, the city/county/state engineer will specify this in his requirements.

A piece of advice though. When you are at the probate office filling out the required paperwork I would shy away from saying you are installing the outlet for a welder. This could raise red flags that may require you to get a fabricators business licence, go to industry safety courses, and be subject to random inspections from the governing occupational safety authorities. I would just say it is for a dryer. Usually you have to have more than 3 dryers to be required to get a launderers business licence.

I'm going to assume you're not in the US, or have never wired a box. The way it's described here >>1067560 is exactly how this is done. US boxes have 220 run to them, which is split into two 110 sides used to power normal house circuits. To get 220 you use 2 breakers, pulling voltage from each side of 110, basically re-marrying them.

A dual 50A breaker will just give op two 50a 110v lines. At least on a US box.

I live in the US fucktard and I know how to wire a fucking panel. the problem is using 2 seperate breakers for something like this. sure you can argue its just 2 breakers, but you shoud never use 2 seperate breakers for a 240 volt load... if a fault happens on one phase the other wont trip and whatever its connected to will still have power making it dangerous. thats why 2 pole breakers exist for a reason so the WHOLE BREAKER TRIPS when theres a fault

now fuckoff

If the welder doesnt need a neutral you would just wire your white to 1 side of the 2pole and your black to the other. If it does need a neutral you would just run 12-3 and the black and red would go to the breaker and the white goes to the neutral bar.

6-3 in this case. apologies.

Are you genuinely retarded? Because at this point, it's painfully obvious to even non-electricians that you don't have a clue what you're on about.

We are not talking about tandem/duplex breakers; the ones that fit two circuits into a single slot. OP wants a double-pole breaker, which is what is REQUIRED by the NEC for 240V circuits.

Yes, the US uses split-phase service and, yes, you do get 240V from using both ends of the transformer instead of one end and neutral. But you can't use two single-pole breakers in place of one double-pole because if one breaker trips, it doesn't automatically trip the other, and the load may remain live. The entire purpose of double-pole breakers is to prevent this.

Additionally, you're a dumbass for thinking two single 25A breakers on a 240V circuit (which is putting them in series with each other) would give you 50A overcurrent protection.

Why are you running a 50a?
My miller only pulls 17amps (yes its 220v).
If you have a big ass welder, fine. But having that large of a breaker for a small draw defeats the purpose.

I have a Lincoln 'crackerbox' 225A welder.
I used it with some 3/16 rods a couple of weeks ago.
It kept tripping the 30A breaker it's on.

The breaker is to protect the wire, not whats plugged in.
>50A wire + 50A socket = 50A breaker
