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?
- http://www.solar-electric.com - low cost circuit breakers (~$10)
- evaluate cost, don't lock into expensive solution
- could be cool but overkill
- http://www.newark.com/wago/859-303/din-mount-relay/dp/28K2321 - DIN 12V5A relay
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
