According to this ECAM ELEC page

Correct! Wrong!

Loss of one generator or TR provide (except if lost is due to overcurrent detection):

Correct! Wrong!

On ground, when only ground services are required, external power can supply the AC and DC GND/FLT buses directly, without supplying the aircraft's entire network. This configuration is selected via the MAINT BUS switch, located in the cockpit.

Correct! Wrong!

This configuration is selected via the MAINT BUS switch, located in the forward entrance area. This switch allows maintenance and ground service personnel to energize electrical circuits for ground servicing, without energizing the aircraft's entire electrical system.

In flight, APU not running, an engine generator has failed. What is supplying the corresponding AC BUS?

What does this "ELEC TR 2 FAULT" message indicate?

Correct! Wrong!

Either the APU generator or external power may supply the complete system (with some galley shedding in case of overload).

Correct! Wrong!

The EMER GEN is being powered by a hydraulic system pressurized by an engine driven hydraulic pump. Pressing the LAND RECOVERY p/b switch will:

Correct! Wrong!

When the LAND RECOVERY pb-sw is pressed in EMER ELEC configuration, ADR 3 is lost, and consequently:

Two main Transformer Rectifiers TR1 and TR2 and one essential TR supply the aircraft’s electrical system with DC current. A fourth TR is dedicated to APU start or APU battery charging.

Correct! Wrong!

Each TR controls its contactor by internal logic.

What does this "ELEC GEN 2 FAULT" message indicate?

Correct! Wrong!

The MAINT BUS switch is located:

Correct! Wrong!

On ground, the inverter is activated, if only the batteries are supplying electrical power to the aircraft, and both BAT 1 and BAT 2 pushbuttons are on.

Correct! Wrong!

An engine generator is driven:

Correct! Wrong!

What is the true statement according to this ECAM ELEC page?

Correct! Wrong!

In case of main generators loss, the emergency generator automatically supplies DC power to the aircraft electrical system.

Correct! Wrong!

The emergency generator automatically supplies AC power to the aircraft electrical system.

Two Electrical Contactor Management Units (ECMU) provide:
