So, I should be able to step it down to 30 amp service, and use the double pole 30 amp breaker in place of the 100 amp I take it...? I was considering going this route as 30 amps would be enough for our needs at this point in time. I'd like to have the vercatility 50 amps brings, but I can easily change that in the future.
I'm currently running four zones, one 20A (kitchen), and then three 15A (entertainment, bath, and living area). This will provide enough room to run everything comfortably around the bus. I like the idea of having a "summer room" supplied via outdoor near the passenger side sometime in the future, therefore the need for some versatility comes into the picture.
Here's the box getting mounted in its new home. I've got enough breakers supplied, so I'll remove what I'm not using to facilitate some extra breathing room.
