Go to Post It's always nice to have the outside party take a look at your code because one of two things can happen: 1. They write it better. 2. They find your stupid mistake. - [more]

Re: Custom power distribution

Breaker/fuse size should be selected based on the wire used, not the expected current draw. Overcurrent protection is used primarily to prevent the wires from overheating and setting things on fire. If you follow the FRC robot rules for matching wire gauge to fuse/breaker rating, then you should be safe.

If you use a single fuse or breaker, it should go between the battery and the terminal block. In this configuration, all wires should be appropriately sized for the rated current of the fuse/breaker.
If you put a fuse/breaker on each branch, then the wires between the battery and the terminal block should be sized to handle the sum of the rated currents.
