I'm looking to wire in a 220v ourlet for the tig I just picked up out in the garage. The breaker panel is already in the garage, but there's no space for additional breakers. The plan is to just run an auxiliary breaker panel for this, and to run some more 110 outlets of it too. I'm mainly just concerned with the welder outlet right now though. Here's my dilema though, I've never done anything like this before and don't exactly know what I need to do for the wiring. I've got everything I need, I just need to know how to wire it all up and I'm not going to pay some electrician a grand for something like this if I can just do it myself. Any help's appreciated. kthnxbye

that link doesn't mention another box.
you would have to remove 2 breakers, and replace with higher amp ones, then run those lines to an aux. box.
then put the two you removed into your new box, and add the 220.
i don't think it would cost much to have an electrician do it.
i won't mess with live 220v. my fiance's dad added a box for me, but it wasn't for a 220 outlet. but thats how he did it.
so now i have a double breaker on the bottom of my box that controls the other box.

So your looking to add a subpanel?

I wouldnt bother adding a subpanel if you have open spaces in your main panel.

simple stuff really, how far away are you planning on adding your 230v plug for your welder? stealth was asking about this same thing a couple weeks ago, search for it and you'll find it. I explained everything pretty damn clean in that thread too

how many amps does the welder draw? im assuming 30?

find the stealths thread and if that doiesnt answer any of your questions pm me and ill give ya some more info

First figure out what size the main breaker to you house panel is. Make sure its at leats 100 amps.

Then figure out what ampacity the welder is. If its 30 amp you will need #10 wire, #8 for 40 amps, and #6 for up to 55 amps.

If you are going to be installing the receptacle near the panel just run some 3/4" pipe from the panel to the closest available spot near the panel. Intsall a 4" square deep box, 2-1/8th", or a 4-11/16ths box if you can get one. Then just get and "industrial raised receptacle cover" for thg esize of the box you installed, that fits your plug and mount it all together on the outlet box. Its self explanitory once you get all the parts I mentioned on how it goes together, if your mechanically inclined. Then just install the 2 pole breaker and your done. The most important thing is to not install a breaker with the ampacity greater than the ampacity of the wire. That will just burn down the garage . If you have any more questions PM me and i'll try to answer them.

find out what kind of panel it is, they make MINI breakers so when you have a full panel, you can use minis to get a couplke more circuits.

pipe on exterior/finished walls looks like ----. and youll spend more money with pipe. buy some type nmb and some plastic boxes and call it good. Like i said find stealths post about his wiring.

saved u even more time https://www.homemadeturbo.com/forum/...?topic=90554.0

and if you decide to run pipe. THHN is more expensive than type nmb. and remember, nmb is not rated for pipe so make sure to use stranded wire(THHN)

Yes pipe looks like ---- but you cant run multi conductor, plastic sheathed wire exposed to damage below 8 feet. So even though conduit "looks like ----" in your opinion its the only way to do it, below 8 feet high, unless he breaks the wall open near the panel to install the milti conductor wire and a plastic box.....how many years have you been in the trade? I have been in it for 16 years and have my contractors liscense. There are many ways to do it, but only one way to do it rite.

If I had an open space in my main breaker, I wouldn't be making this thread and it would already be done. My main concern was figuring out the best/most conventional way to get a source of power to the aux. panel, and where to grab it off of the main panel. The easiest way that i've heared was to use the breaker in the main panel that's for the washer/dryer, and use that as the source for the aux. box and then just run 2 separate breakers in the aux. box for the welder and the washer/dryer. Everything is getting wired up for around 50 amps with 6 gauge wire. with a 50 amp breaker

read what i wrote

No space on the main then buy some minis. they even make mini 2pole breakers.

so no need to a sub panel

They dont make mini 220 volt breakers . Minis run off of the same leg and only allow you to run 2 circuits off of the same phase. You need 2 phases, Aand B, to get 220 which means minis wont work. Stop giving advice about something you know nothing about.
