Galley Power Supply and Distribution - Schematic ** ON A/C NOT FOR ALL
The power supply provides the galley assemblies with 115 V AC through the three phase normal busbars 1XP and 2XP. Six triple core wires (feeders A to F) distribute the power to terminal blocks in the forward and aft galley area. Vendor wiring distributes the power to the galley units. The wiring is connected to the terminal blocks by the electrical connector.
The maximum available load for all galleys is 50 KVA. The load is distributed as follows:
The maximum available load for all galleys is 55 KVA. The load is distributed as follows:
The maximum available power for all galleys is 55 KVA. This power is divided in two parts as follows:

The load is distributed as follows:
- Network 1 = feeder A, B and E with 30 KVA,
- Network 2 = feeder C, D and F with 20 KVA.
Circuit breakers protect the feeders. Power contactors switch the power.

The maximum available power for all galleys is 55 KVA. This power is divided in two parts as follows:
- Forward feeder between 0 KVA or 40 KVA
- After feeder between 0 KVA or 30 KVA.
Circuit breakers prevent the feeders. Power contactors set the power.
4. Operation/Control and Indicating
The power contactors for the galleys are controlled through control relays as follows:
With the APU generator running or with external power supplied you can supply all feeders with power (on the ground). With both engine driven generators running, you can supply all feeders with power (on the ground or in flight). With only engine 1 driven generator running, only feeders B and D is supplied. Feeders A, C, E and F are shed automatically (on the ground or in flight). You can manually shed all the feeders to the galley with the pushbutton switch 2XA GALLEY OFF in the cockpit (on the overhead panel 35VU).

Control relays control the power contactors for the galleys as follows:
- When the APU is in operation or when external power is supplied, you can supply all feeders with power (on the ground).
- When the two engine driven generators are in operation, you can supply all feeders with power (on the ground or in flight).
If one engine is available, feeders A, D, E and F are shed automatically (on the ground or in flight).
You can manually shed all the feeders to the galley with the pushbutton switch GALY&CAB in the cockpit on overhead panel 35VU.
