6. Circuit breakers and circuit breaker switches. The
primary circuit breakers and circuit breaker switches for
the aircraft are located either on the center pedestal panel
or the instrument panel. Each individual circuit
breaker/switch is labeled for the particular electrical circuit
protected. In the event a circuit becomes overloaded, the
circuit breaker protecting the circuit will pop out or the
circuit breaker switch will release to the
OFF
position. The
circuit may be reactivated by pushing the circuit breaker
button back in or by cycling the circuit breaker switch
thereby resetting the circuit breaker. Circuits for devices
using direct power feed from the battery are protected by
circuit breakers located directly beneath the external power
receptacle on the right side of the backwall in the engine
area.
7. Fuses. Nonessential equipment electrical circuits
not protected by circuit breakers are fuse protected. The
fuses are located on the left side of the center pedestal
(Figure 7-12). For aircraft S/N 5134 and subsequent, the
fuse panel is an option.
8. Current Limiters. The current limiter, located on
the right side of the backwall in the engine compartment, is
a non-resettable fuse that protects the main electrical bus
in case of a direct short to ground. Optional current limiters
are installed as needed for additional electrical circuits.
