Just be aware of the wire sizing/length vs. ampacity of the circuit. Most circuits can be a 10% voltage drop, but other circuits, amps etc. may require a 3% voltage drop. The length of run for a guage is both the positive and ground loop combined.





So so feeding a total of 25' out and back from/to the battery is ok for a 10% V drop with a run of 6ga. and 100a.

Not a bad idea to put a 60 amp circuit breaker back in the battery compartment on that 6ga. Main Buss.

Ya, you definitly want a circuit breaker at the battery. I put a 100a C.B. at the battery and fed the Blue Sea 6-ckt +/- fuse panel with 6ga., but I mounted mine in the head/storage locker on the port side, carpet covered plywood aft bulkhead. A much shorter run than the starboard side. I have my vhf and fishfinder directly above on the dash. When I added trim tabs and an amp later to the helm, it was an easy, short run across the ski locker ceiling and into the helm for the power/ground feeds.

I did not fill the panel to it's amperage limit.



Across the top of the ski locker.



Also remember that a circuit breaker is designed to trip at 80% it's current rating.
