How to wire in a 220 plug

[Triple 7]

I purchased a new welding mechine that needs a 220 plug. I was thinking about doing it myself, but I am a little nervous. To my understanding all I need is a few feet of 10-3 romex, a double pole 30 amp breaker and a recepticle. Is that about it? I am all about a good DIY but I don't want to mess this up. Any advice?

I wanted to run a new wire from my garage to my breaker panel but my panel is full so I tied mine into my dryer wires, I know it's not the best way but it works until I get my barn finished. The only thing is I don't run the dryer when I'm welding.

Pretty much it. 10-3 will have a bare copper wire (ground), white will be the neutral or common wire then black and red are both hot.

Bare copper wire connects to the round or "u" shaped pole on the receptacle and to the grounding bracket in the panel with the rest of the other grounds.

The white common wire will connect to the spade opposite the ground on the receptacle (usually the top prong). In the panel it will connect to the same terminal the other white wires are connected.

The red and black will connect to the two prongs left on the on the receptacle. Does not matter which side as they are both 110v and hot wires. In the panel the red will go to one pole and the black to the other pole on the breaker.

Be sure to kill the master breaker for safety and hook the wire up in the above order. The concept is by hooking the hot wires up last you have less chance of being shocked and by having the ground wire hooked up first it gives a potential short a path to go other than you.

If you still don't feel comfortable call an electrician. I am sure there are probably several on this site.

Hope that helps.

That is correct.
1st ensure power is off to the panel turn off main.
2nd remove the dead front
3rd ensure power is off to panel
get 10/3 with ground
1 wire goes to ground
1 wire goes to nuetral buss bar
the 1 into each side of the double thirty
build your plug snal into panel

Due to liability I will say you should contact a trained and licensed electrician for your own safety.

Is 30amps enough? For my welder plug I had to run #6 wire on a 50amp breaker. Might want to check minimum circuit amps for your welder.

very carefully!

I had to use a 50A as well

Its pretty straight forward, if you are not an electrician DO NOT work the panel hot. Kill the main feed to the panel before landing your wires.

This is not a good idea

That's pretty much what you need to do I am running a 50amp also

[holepuncher]

pay a license to do it, you get a warranty, you want end up on the evening news or in the Obituaries, your house wont catch fire, and you wont burn up your new welder. As a licensed electrician I cannot give you any advice other than the above.

i don't think 10-3 is heavy enough wire---

[Triple 7]

Well I ended up just having it done. I watched the guy the whole time and he did it the way I was talking about. He did wire in a 50 amp breaker. He said a 30 might work but he suggested a 50.

Smart

JK Glad you got it working.
