For multiple amplifier installations where distribution blocks are used, each amplifier should have its proper-rated
fuse, or breaker, installed between the amplifier and the distributon block within eighteen 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 eighteen inches of the battery's positive terminal, with a fuse
or
breaker
rated at least
to
the sum
of
the individual amplifier's fuse values
