For multiple amplifi er installations where distribution blocks are used, each amplifi er should have its
proper-rated fuse, or breaker, installed between the amplifi er and the distribution block within seven inches
of the block, or on the distribution block if it provides for fusing. The primary power wire should also be
fused between the battery and distribution block, within seven inches of the battery’s B+ terminal, with
a fuse or breaker rated at least to the sum of the individual amplifi er’s fuse values, but not to exceed
1.5-times the sum of the individual fuse values (not to exceed the ampacity of the thermal insulation of the
wiring as shown in U.S.C.G. CFR33 183.425, Table 5). See the diagram below.
NOTE: Seven inches is the standard distance under U.S. Coast Guard CFR33 for placement of fuses or
breakers as required by law for new boat manufacturing. We recommend trying to adhere to this standard
in a consumer installation. Failure to do so does not mean you are breaking the law, but it does put the
safety of your boat and passengers at risk in the event of a power wire short circuit.
