Fuse box safety question. Answered
I am currently working on turning my van into a full-time home and I'm throwing the rule book out of the window. I have 600W of solar and 180Ah of batteries and I'm working on the wiring
Normally, the high current lead runs from the batteries to a fuse box and then around multiple circuits with a fuse to match the demand in that circuit. I'm looking to decentralise the fuse box so that the main cable has a 50A fuse and runs around the entire van feeding junction boxes and modules. Each module contains its own fuse, an ethernet connection, possibly a buck converter and whatever it needs to do its job. Every module is, therefore, able to report faults and output to any other module that's interested. If a fuse blows, a simple ping across the network will tell you which module is not responding and, therefore, which fuse needs replacing.
Is there a safety issue I've not thought of with this approach?
