Circuit breakers are installed on the battery switch to
protect various system components. The SHIP SYS-
TEMS breaker supplies power to all DC electrical
components except the aft and forward bilge pumps,
ignition, and instrumentation. Additional breakers are
located in the cabin circuit breaker panel. The circuit
breakers and fuses are labeled for amperage and use.
A helm circuit breaker panel is located underneath the
helm seat. These circuit breakers provide additional
protection for certain component wiring which are
identified on the panel itself. See Figure H1.
