Craig- A little hijack here-- I would be interested in your creative solution to the inverter issue since I have been known to forget to turn the water heater off before switching to the inverter. I have considered using a sub-panel, but have been managing with putting reminder markers on the switches. Sorry
I'll try to make this simple... Everything I have is 110V. No stove, oven, or large AC system. I have a panel with breakers. There is a left side and a right side to the panel (ya, it zig zags, but lets not confuse the facts). Obviously the panel is intended for 220V systems (two 110V leads). But, since I don't need the two separate leads that make 220V, I have jumpered the top of the two rows of breakers. (ran a heavy wire from one side to the other, like two inches). Now, I have two rows of 110V all on one 110V supply wire.This make sense so far?So, if I was to hook up a 110V 20Amp or 110V 30Amp, or 110V 50Amp it wouldn't matter, my entire panel would be hot with 110V. BUT, if I hook up 50Amp 220V (two 110V leads) now I have a problem. My little magic jumper wire is going to blow the lid off the campground... and maybe my bus. So, I got this wild idea that if I pull that little magic jumper wire out and put a switch inline, then make sure that switch is off (open) when I have 220V supplied to the box that I will magically have 110V on both sides of the box, with 50Amp supply on both. But, when I only have 110V supply, I can turn the switch on (close) and have 110V on both sides, but only the amperage available from the one line.With me so far?Ok, be kind. I realize that if my brain didn't engage and the switch was on (closed) when supplying 220V that we would have issues. Yes, it can be done with a relay, but the result is the same, if the switch is closed - poof! There must be a fool-proof solution. Also, someone mentioned that the readily available RV adapters combine the lines.. is that true? If that's true, I can let the adapter take the place of my magic jumper wire and the single 110V supply will automatically go to both sides of my panel.... until I hook up my generator.Grab your sling shot... time to throw some stones in my theory.
Gumpy- Did you mean 6/4 cable for the 50 amps?
