Rear Electrical and Long Wires

Hi all,

I’m sure this has been brought up, but I could find no direct advice.

After initially planning to put all my electrical behind the driver, I now want to save living room space by putting the electrical under my bed in the rear of the bus. I would place the batteries in a sealed container with venting to the outside, and the inverter, fuse box, charge controller, etc would sit next to the container.

One potential issue is that I would have to run a long DC wire from the bus’s alternator/isolator from the front of the bus to the rear. Would it be problematic to run such a long wire? (I would use stranded)

Other questions
Has anyone built a sealed container for their batteries? One with venting? Would appreciate examples or guidance.
Has anyone else put their electrical under the bed next to their plumbing? — apart from separating the two and raising the electrical above the floor, any other safety considerations?

Thank you

There's no difference between a 100' run vs a 1' run in terms of the calculations you should perform to determine the gauge of wire needed. For a given voltage drop, you're going to need a larger gauge the longer the run gets, but I wouldn't consider that problematic, unless you're considering the increased expense.

Check out the 'Blue Sea Circuit Wizard' in the app store for whatever phone you own.

I would avoid putting an electric system anywhere near plumbing connections.

long wire run alternator to battery

use charts for length of wire 12volts check amperage and voltage for the length intended. a full length wire alternator at one end and batteries at the other end i would like to see one fuse close to the alternator and one fuse close to the batteries, isolate that long wire from power sources in case the wire has a problem and short circuits.

Another thread with the same general question about alternator charging here: https://www.skoolie.net/forums/f49/e...iew-40004.html

Battery question: if you are using LiFePo, no need to create a sealed container, because there is no potential for fumes. Just use common sense to avoid placement where it could get wet.
