Term
| What are the ECB functional states? |
|
Definition
• Auto/On - normal state, white outline with a green interior • Auto/Off - ECB turned off by the ACS, white outline with a gray interior • Tripped - ECB off due to a circuit fault, amber • Pulled - ECB opened by the pilot, gray • Collared - ECB locked out by maintenance technician, white outline with cyan interior |

Term
| With one generator operative, what systems are automatically load shed? |
|
Definition
The air conditioning system is the only system load shed. |
|
|
Term
| At what temperature do the battery heating pads operate? |
|
Definition
| The ACS enables the battery heating pads when the OAT is below 10°C. The ACS turns the heating pad off when the temperature sensor rises above 80°C, and turns the heating pads on when the temperature sensor falls below 70°C. |

Term
| Ten contactors connect various components of the electrical system. What are the ten contactors? |
|
Definition
• System battery • Left battery bus • Right battery bus • Start battery contactor • Bus Tie contactor • Left generator contactor • Right generator contactor • External power contactor • Left forward circuit breaker / contactor • Right forward circuit breaker / contactor |
|
|
Term
| What electrical devices are connected to the hot battery bus? |
|
Definition
Entry, overhead, and baggage compartment lights are powered directly from the hot battery bus allowing them to be turned on without powering the avionics. These lights are on a timer to avoid depleting the batteries. |

Term
| The Generator Control Units (GCUs) regulate the generator outputs to what voltage? |
|
Definition
| The GCUs regulate the 30 VDC generator outputs to 28.5 volts DC. |
|
|
Term
| The external power contactor automatically opens when what conditions are detected? |
|
Definition
• External voltage is greater than 29 VDC at any time • Aircraft current draw is greater than 400 amps • External power current draw from the aircraft is greater than 5 amps • External power voltage is less than 24 VDC for more than 45 seconds • External power voltage is less than 10 VDC at any time • When generator power is available (online) after engine start |
