220V plug wire question - TyG - 12-26-2023
Hey all,
I am putting in a 220v plug for a Lincoln BuzzBox welder. 50amp breaker. I would like to run across a two car garage, say 30' total run. I was planning on using 6 AWG wire for the two hots. Should I also use 6 AWG for ground wire also?

Pretty sure if you buy 6/2 with ground that ground is 10 gauge.
Are you pulling individual strands or buying premade 6/2?

I bought a 2 foot sectin of 6/3 w/ground just to get a quick job done, but it looks like it would be way cheaper to run individual. What gauge ground would be recommended? I was honestly thinking that I needed 6.

Joseph was correct #10 for the ground wire. IF the ground is just used as a ground and not as a neutral. Roly

A buzzbox is 30 amps you would need a 10 gauge for 50 feet.

Your ground needs to carry the same current at your hot's and neutral, otherwise your ground becomes a fuse. So they have to be sized the same.

What does the NEC say ? If it is just used as a equipment ground use a 10 ga for 60 amp breaker circuit. Roly
NEC 250.122

I'm not an expert by any means, but strongly suggest that you read the NEC section on welder circuits, Article 630. My AC/DC buzzbox is running on a NEC-legal circuit of 3 10AWG, THNN conductors. Red Black and green.
Duty cycle is everything with sizing circuits for welders.

You are correct for a commercial shop, BUT in a residential situation where the house may be sold and a new owner plugs something like a dryer into the outlet, What would happen to the wiring ? Extra crispy comes to mind. Roly

As long as the breaker is sized for the wire the breaker opens. No harm no foul
