> [@Snnipe\_70E](#): > > Correct. this means that you have only 30 amps of 240 VAC power. I have a 70 amp sub panel, I will check out the wire size going to the outlet, if they will handle 40 amps I might upgrade the breakers to 40 if I have trouble using small rod on the 30 amps. Pretty sure the wire size is 10guage with a 12 foot run to the outlet. ---

Pretty sure the wire size is 10guage with a 12 foot run to the outlet. 10 gage is good for 30 amps. [Previous page](https://boards.straightdope.com/t/welder-wiring/742767.md?page=1)
