I need to check how my gen set in wired. I know I have one neutral and two 110V legs, however, it is not 220V between the two legs. It is an Onan Marquis 6.5 gas and I have the book I just have not looked it up. Right now I have the 50 amp shore power wired as normal with each 110V leg going to one side of the 220V panel. As the gen has two 110V legs I just wired one to each side of the 220V panel as well. I am leaving out all the transfer switch wiring for the purposes of this discussion. I don't need 220V for anything. I will look at "da book" & see what my options are.
Some of the Onan 6.5's were not wired for 220 and only 120 with 2-breakers on the same leg. Something cheap about that deal.
