I'm rewiring my boat (36', all wiring already removed) and want to know if it's better to run all home runs to each device from the DC panel or to use terminal blocks for groups of devices. For example, devices up forward in v berth (fan (1), berth light (1), storage compartment lights (2), is it better to run those to their own breaker on the main DC panel or run them to a terminal block in the v berth area, then a single home run from that terminal block to the DC panel breaker (correctly sized for voltage drop/distance/load). All lights are LED and the fan is 1 amp. Boat is 12v system. For larger consumers (fresh water pump, sump pump, washdown pump, etc...) I'll use home runs for those. This question is more focused on lighting, 12v outlets, and fans. I seem to have a lot of them (lights in the larger compartments, under cabin sole to illuminate bilge, cabin lights, low light lights ("night lights", etc...). Each fixture's leads will be connected to feed wire (whether home run or not) with a terminal block to eliminate splices.
Attached is an example.
Thanks
