I got mine Wed. but wont get to play with it till the weekend
Mine was delivered Wednesday and I don't expect to get to it for about 2 months
Plenty of time to think up projects.
.This is fine advice, but copper isn't cheap. Here is the relevant table from the NEC:
View attachment 374215
The PA300 has a 60% duty cycle at maximum amperage. At max amperage, it pulls a sustained 46.8 amps. At a 60% duty cycle, a non-motor generator has a duty cycle multiplier of 0.78. 0.78 * 46.8 amps = 36.5 amps. Looking at wire gauge tables, the derate basically seems to drop you down one wire gauge size, so actually I would probably agree with Boomer that you may as well keep life simple and just wire up the circuit with a 50 amp breaker and the appropriate size of wiring. Unless maybe you have a really long cable run and the difference in cost on the wire to go down one size will matter.
EDIT: I am not an electrician. This is not professional advice.
