ABSTRACT
Electrical power is supplied to the various loads in the aircraft via common points called busbars. The electrical power distribution system is based on one or more busbar(s); these provide pre-determined routes to circuits and components throughout the aircraft. The nature and complexity of the distribution system depends on the size and role of the aircraft, ranging from single-engine general aviation through to multi-engine passenger transport aircraft. For any aircraft type, the distribution system will comprise the following items:
busbar
protection
control
wiring
loads.
