Solar charger fuse is inline automotive.
Blue Sea Ancillary
This distribution setup is used for power distribution in the saloon; it's in the same physical area as the batteries. Distributor is a Blue Sea Systems ST compact 8-circuit (5046) with 10-32 stud, and 8-32 screw terminals.
Always on distribution
This powers low draw devices that should be powered without the house switch being engaged. Basically, lights. Located in the wiring cabinet above and behind the chart table. Wired to supply side so it's always got power, bar the local fuse blowing.
Water pump
Wired via a relay so that the switch by the chart table just activates the relay, and the pump gets power from 6mm2 direct from the battery compartment.
The relay is the same as the one for the engine starter, 12V 40A SPST with 30/85/86/87 terminals, normally open.
