Anybody using marine trip resettable circuit breakers

I run self resetting breakers for the entire main electrical system and then the cabin is also on fuses for the details. (stereo, interior lights, dash lights and such)
I also installed a headlight relay set, but used 4 separate relays (one for each bulb filament) so if I loose a relay it will only affect one function of one bulb.
It wont shut down both bulbs on high or low beam either one.

The self resetting relay handles the heavier loads like the starting and charging system, electric fan, ignition and headlights
(You know, the important stuff) just fine.

Del feels I should have the main relay for the entire system capable of handling the same amperage as the alternator can put out in case the alternator needs to charge wide open at some point, but the 30 amp in there has never tripped yet in two years so I figure if everything can run through it under normal max load conditions then the lower the trip amps the better.

I have run everything you can think of in the car all at the same time without ever having it trip.

The headlights relays are connected directly to the downstream side of the breaker with 8ga wire run directly to the headlight relays with 8ga grounds from the bulb sockets right to the radiator support as is the electric fan, so those are both live all the time.
The fan is completely automatic no matter if the ignition is on or not, and the headlights, markers, tail and brake lights. (like original) they can come on without the ignition needing to be on.
