I will try to accurately express my question.
I have a 4 (red, white, black, ground)wire connection to a 30 amp breaker to tie my generator to my house. Weatherproof outside box designed for a generator connection.
I recently bought a Hobart mvp 210 welder which is a 120/240 v welder. It tells me in the manual that for the 220 side I only need 14ga wire but I want to use 10 ga. This question is only about the 220 side.
I would like to use this same connection to power my welder. The welder has a 3 wire connection.
I want to make an extension/transition cord from 10 ga wire with 3 wires (white, black, g) (ok I am using 10/2 romex) to connect my welder to my circuit.
My question is --- what do I do with the ground connection I have at the weatherproof box at the house since I only have 3 wires? Tie nothing to it or jump it to the lug that would have been common?
Basically I have a 3 lug (prong)plug at the welder end and a 4 lug (prong) at the supply end with romex with 3 wires in it and I want it to be safe. I already assume I should probably not make an extension cord from romex buy it is my cheapest choice.
