I know this could be a bit of an open invite. There are so many different ways to do electrical within a bus but I figured I would post my layout and general plan. I would love to get some feed back as I have not yet commited to any particular electrical components or wiring but I am about to in the next could of weeks.
My intended use of our bus is for an RV that will be with our family for 20+ years. We do not plan to live in it.
Generic floor layout (Mid ship door once done will push the front seat forward)
Electric and plumbing layout
Here is my layout that I have in mind currently. I am about to lay the flooring down and plan to place any cross run electrical between the metal floor and the subfloor, in the same space as 1 inch r5 insulation will be (maybe with conduit). The length runs will be run along the sides of the bus behind the walls.
Specifically an area that gets a bit foggy is with inverters & converters, fuse panel options, battery chargers, electrical health system monitors, etc. I have bought nothing yet. Currently I plan to purchase 12g standard household wiring along with some smaller cauge stuff for led lighting. I have seen a few $250+ fuse panels which seem rather expensive for what it is. Inverters and Converters vary greatly... I feel like I could spend a year researching.
Lastly my thoughts are to go with solar for charging and shore power for when avaialble. The fridge im looking at is 12v dc and may have 110 switching. Mostly going to charge tablets, use a gridle or toaster in the kitchen, and tv/components. If on shore power we may even run an indoor ac unit and the water heater can run on electric.
Thanks for reading and any advice or questions are greatly welcomed.
