Re: Grounding shore power to the skoolie's body.
Julie- Thank you for taking the time to write all of this (sorry about the late reply, but my spam filter caught this). I am going to exchange the box for the correct box. As this is my first breaker box ever installed, I didn't think to look for two bus bars when I bought it; I obviously bought the wrong box. I was also at Home Depot today and bought "Wiring 1-2-3", as I don't want to kill myself or anyone else trying to wire this party bus of ours. So, thank you again for taking the time to explain. And, I do intend to plug the bus into a 30 amp plug that I am having put into my garage so that I don't have to run the generator at my house when working on the interior of the bus. Not sure how all of that plays in, but I'm hoping my new book might explain it all a little better to me.
For a second question, I'm wiring a friend of mine's trailer and I'm going to put in a Marinco 30 amp inlet to feed the trailer. He does not have a rooftop AC now, but might add one later. I know the rooftop unit draws about 20 amps, so I would still have 10 amps left over for some 110v outlets in the trailer. How do I "split" the hot wire from the inlet plug to feed a 20 amp breaker and a 10 amp breaker (I want to put the AC on it's own breaker, and the 110v outlet on a seperate breaker, like I'm doing in the bus above, but this time I only have one power source, the 20 amp cord coming in). Thoughts? Thanks!
