AC Power Supplies
10. A G4B compass system requires 115 volt single phase AC power
supplied by a rotary inverter under the Navigator’s table. Power for the
inverter is through a circuit breaker in the MEP. Control of the inverter
is by two buttons on the Navigator’s panel, marked ON and OFF. An
associated doll’s eye indicates when the inverter is running.
Distribution
11. The starter motors, feathering pumps and inverter are supplied through
their associated relays. The main electrical panel CBs are listed in Table 1.
