The standby power switch gives you manual control of the AC
and DC standby power bus sources. In the auto position, the AC
standby bus receives power from AC transfer bus 1 and the DC
standby bus receives power from DC bus 1 when these sources
are available. If the sources are not available, the AC standby
bus receives power from the static inverter and the DC bus
receives power from the battery.

These are the effects of the standby power switch in the other
two positions:
* De-energize the AC standby bus and the DC standby bus
(OFF position),
* Energize the AC standby bus with battery power through the
static inverter and energize the DC standby bus with battery
power (BAT position).
AC Systems, Generator And APU Module (P5-4)
You use the ground power switch to control external power to
the AC transfer buses. The blue GRD POWER AVAILABLE light
above the switch shows if the ground source is connected and
quality is good. Both AC transfer buses receive power when
you put the ground power switch to the ON position. Any initial
power sources are removed before the transfer buses receive
external power.
The bus transfer switch gives you manual control of the BTBs
and the DC bus tie relay. In the AUTO position, the BTBs and the
DC bus tie relay operate automatically as necessary.
In the OFF position, the BTBs open and isolate the AC transfer
buses from each other if one IDG is supplying power to both AC
transfer busses. The DC bus tie relay will also open. This
isolates DC bus 1 and DC bus 2 from each other. The position
also resets the BTB trip circuits.
You use the GEN 1 and GEN 2 switches to supply IDG power to
an AC transfer bus. The AC transfer bus on that side goes to
IDG power when you temporarily put the switch to the ON
position. Any initial power sources are removed.
You use the APU GEN switches to supply power to the AC
transfer buses. There are two switches because there are two
bus tie breakers (BTBs) that supply power to the AC transfer
buses. Both AC transfer buses will receive APU power with
operation of just one APU GEN switch if both AC transfer buses
do not have power initially or if external power is the only
source on the AC transfer buses. If the AC transfer buses do
have power initially from two power sources, (for example both
IDGs) then only the AC transfer bus on the same side as the
APU GEN switch you operate will energize with APU power.
The blue APU GEN OFF BUS light comes on when the APU is
ready to supply electrical power.

You use the ground service switch to supply external power to
ground service bus 1 and 2 with external power connected. This
makes it possible to supply electrical power for cabin servicing
without going into the flight compartment.
