Its not the same thing. You cannot legally supply each leg with a different separately derived device. Parallel generators double output but its for 120 only.. theres nothing to wake up and learn about. Ive been an electrical contractor for nearly 40 years. If you want to do this, than do it. Just don’t expect anyone to condone it or tell you its ok to do.. personally i am done with this, i am unsubscribing to it.
It sounds like you are saying I am expecting to get 240 volts from the two 120 volt legs of the parallel switch/kit. I AM NOT. I am only expecting to get two 120 volt legs from the parallel receptacle for a total of 50 amps service. That's what Champion says the #100319 output is.
