Power Distribution Module (PDM):
• One location for all fuses, relays and circuit breakers.
• This distributes power to all components.
• All Primary circuits have either self-resetting circuit
breakers or manual resetting circuit breakers.
o Self-resetting circuit breakers reset when
power is cycled to the system.
o Only exception is 5a circuits use lighted fuses
due to the unreliability of circuit breakers at
low amperages.
• All non-essential functions have fuses.
