#1. The purpose of a synchronising bus bar is to:

• Aenable interconnections to be made between generator bus bars.
• Bsupply essential services.
• Cmonitor on-load currents.
• Dinterconnect DC bus bars.

#2. Fuses and circuit breakers are fitted:

• Ain DC circuits only.
• Bin both AC and DC circuits.
• Cin AC circuits only.
• Donly to protect the wiring.

#3. Where the aircraft’s main electrical supply is A.C, DC requirements are met by:

• Abatteries.
• BT.R.U.s.
• Cinverters.
• Da static inverter.
