Hello, I am the proud owner of a self built Tiny House. For those unfamiliar, its basically an RV, but built like a small house/cabin on a heavy duty flat bed trailer. I am experienced in pulling wires and trim/finish electrical. However, that was in residential, and this is slightly different than that, and requires some engineering that I am not comfortable 'winging' at this point. I am planning a small kitchen, (dorm sized fridge / range exhaust), 8 lights total, desktop computer, an electrically assisted composting toilet and a combo washer / dryer unit. There will also be misc small electrics, but the range will be propane for cooking, heat from a small wood stove, to alleviate some burden on the electrical. I plan to one day go completely solar, so I need to factor that into the current design. I would appreciate some help with the planning side of this. From research, 50A RV seems be the best choice. Is that correct? Or could I skate by with the 30A system? What circuit box / breakers / set up would be best for me? If anyone has thoughts, or a website for information (Most that i have found on the subject seem to be outdated) would be greatly appreciated.

Hi, I am replacing the ceiling fan with just a ceiling light. The ceiling light has 3 wires, black, white and green (I assume it's the ground wire). When I wire everything together, the light switch would not turn off the light. The switch has 5 wires: 2 blacks (one from the light and one from the power source), 2 white (one from the light and one from the power source) and one red wire that comes from the light. When I first removed the switch, the two white wires were connected, but not to the switch. The two blacks were joined, then attached to the switch. And, the red wire was attached to the switch directly. How do I wire the switch to make it work? Many thanks for your help!
