Many builders and repairers now set up a sub panel with non switch breakers (like the pop out type) just for such things. When I do any
wiring jobs I always set it up like this and this is how I have it on my own
boat. So the answer is yes you want to make things like
bilge pump autos, idiot proof so they do no accidentally get turned off. I run the
power to this sub panel off the non switched terminal on the battery switch rather than from the battery its self. Keep this sub panel close the the battery switch, this makes for cleaner
installation. Check ABYC regs for
wiring.
