In the event it becomes necessary to replace
a fuse or an electrical breaker, REPLACE THE
FUSE OR BREAKER ONLY WITH A FUSE
OR BREAKER OF THE SAME RATING. The
amperage is marked on the fuse or breaker. It
is recommended that you carry spare fuses and
breakers. Refer to individual component user
manuals for the proper fuse and breaker sizes.
Use of higher amperage fuses or breakers is a
fire hazard.
Use fuses and breakers having the same
amperage rating as the original or as specified.
If a fuse or breaker is replaced with one of lower
amperage, it will not be sufficient to carry the
electrical load of the equipment it is connected to
and will cause nuisance failures.
Conversely, if a fuse or breaker is replaced with one
of higher amperage, it will not provide adequate
protection against an electrical malfunction and
could create a possible fire hazard.
Some of the various types of fuses and breakers
used on your boat are as follows:
