Conductors for standby generators need to be sized not less than 115% of the generators nameplate rating: NEC 445.13. In this case 50A x 115% = 57.5A, so you need to go with #4 AWG minimum in this application.
I forgot about the 115% rule. The genorator is rated at 50 amps. It's been awhile since iv'e installed one. It is going to be one of those Bryant all-in-one setup. The only proble is that where he wants it is about 40' away. And he wants to try to reuse what he has. Thanks again Sam
