General Specs

Marine switch/fuse/circuit-breaker equipment is expensive. Circuit breakers are nice, but I'm fine with fuses as long as they aren't glass which take up space.

I'm thinking of combining a basic switch block (could be pre-made) with automotive style fuse blocks with ATO/ATC/APR fuses (the square plastic tab).

Lastly I am considering using old-school telecom cable lacing in place of cable ties. Not only is it knot-based, but looks cleaner and doesn't cut hands open.

DIN Rails

Could DIN rails be used for circuit protection, distribution, and possibly relays for switches?

Types

  • UL480 - branch protection
  • UL1077 - Supplementary protection

Labeling

  • Should I call it a Power ID (PID)? :)
  • Documented starting at battery flowing to device
  • Circuit##-Switch##-Device##: D##-S##-C##
  • Example, VHF: C04-S07-D13
  • Allow for daisy-chaining devices if down a common feed?
    • Example, Bow/Stern Light feedline: C01-S01-D01-D02
