4G6: DC Power Main Breaker Panel
Note: The switch panels are made from a high-gloss material, so
it is impossible to photograph them “straight- on”. That is why they
are shot at an angle....
The nerve center of the DC electrical system is the DC circuit
breaker panel by the helm. On this panel are the switches that
control power to the boat’s various systems. 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. Examples would be
the breakers for the horn and electric head. If on, the horn won’t
work unless you push the horn button, and the head won’t flush
unless you are there in the head compartment to operate it!
Other breakers also serve as the item’s switch. An example of
this would be the navigation light breaker or the macerator pump
breaker.
The Main Battery Switch should always left “On”. NEVER switch
this “off” with the engines running except in a dire electrical
emergency!
