Hi all; Quick question regarding a generator cord and inlet box I inherited from my Father when he updated his generator transfer box setup. The generator cord and inlet box are 20A. However, the generator I bought only has a 30A, 240V outlet. If I wanted to use the inherited cord and inlet box, can I change the 20A plugs on the cord and inlet box to 30A? If I'm not mistaken, the big issue would be if the cord had the correct gauge wire in it to carry 30A. (Just for the sake of argument, please assume that I'll be able to get the plugs removed from the cord and inlet box.) Thanks in Advance!
