For the first time we have our 376THS in really hot weather. When we have all 3 A/Cs running we are consuming roughly 40 amps or 4200 watts according to my Power Watchdog. How much more power can I use (safely) if I am hooked up to a 50 amp shore power? The simple answer (10a) or 1200 watts more? Are there 2 - 50 amp legs to shore power (2 x 50 amp x 120 = 12,000 watts available?). I know I need to be judicious on which circuit to use as to not overload the breaker.

Thanks everyone!
