I need info on generator power.

[skennedy6009]

I have a older generator that I want to use sometimes to power the Airstream but I need to make a cable that will change the old style 4 wire Generator plug to a 3 wire (30Amp) or 4 wire (50amp) RV plug. I have a L14-30p for the generator plug that has a ground, two hots, and a common. I think this wiring would be 220v using a 14-50R plug 2 hot, 1 common and 1 ground (50 amp RV plug) or I can use 3 wires 1 hot, 1 common and 1 ground for 30 amp plug TT-30R. I would just leave one hot on the Gen plug and cut the other wire. I think would be 120v 30amp wired this way. My question is when I hook up my Airstream to a 50 amp service at a camp ground is that 220v/ 110v on each leg? Will the 50 amp 4 wire 220v rv plug fry the airstream? Thank for your time.

Welcome to the forum!

You may find a better audience in the Generator etc. sub-forum, where topics like this are discussed often:

At the top left of that page, in the line with the blue ">" symbols, you could also "bounce up" [my term] to the broader Electrical etc. forum:
