4G5: The DC Electrical Panel
The nerve center of the DC electrical system is the DC
circuit breaker panel by the helm. On this panel in the
left and center columns are the switches that control
power to the boat’s various systems. On the right of
the panel are the switches for the engine(s) and the
main battery switch.
Just as in your home, most of these switches are true
“circuit breakers”: they feed power to somewhere in the
boat where there is another switch which, in turn, turns
the item on and off. An example of this would be the
circuit breakers for the horn and electric head. If the
breaker is turned on, the horn won’t work unless you
push the horn button, and the head won’t start flushing
the moment you turn the breaker on, either!
But some of the other breakers also serve as the switch
for the item. An example of this would be the navigation
light breaker or the macerator pump breaker.
So here is the list of switches and how they’re used:
Key: “B” = “Breaker”
“S” = “Switch and Breaker”
“MS” = “Momentary Switch”
Green = Leave this Breaker on Always
Blue = Have this breaker “on” when aboard the boat
Yellow = Use when Item is Needed
Red = Use with Caution in Exceptional Circumstances
