Definition
A circuit in a multi-generator electrical system that automatically equalizes the load carried by two or more generators operating together on a common bus, so that each generator supplies its fair share of the total electrical demand.
Plain English
When an aircraft has more than one generator feeding the same electrical system, this circuit makes sure they share the work evenly instead of one doing most of it while the other coasts.
Context Anchor
Seen in aircraft electrical system maintenance, especially when checking generator operation on aircraft that use more than one generator.
Derivation
From 'parallel,' meaning side by side or working together. In electrical terms, devices wired in parallel feed the same bus at the same time. The 'paralleling circuit' is what keeps them cooperating rather than fighting each other.
Why Pilots Care
Prevents generator overload, maintains stable electrical power, and avoids system failures during flight.
Intuition Check
Paralleling does not mean the wires are simply drawn side by side. Here it means power sources are connected so they can supply the same electrical system together.
Example Sentence 1
After the right generator tripped offline, the technician suspected a fault in the paralleling circuit because the loads had been drifting unevenly before the trip.
Example Sentence 2
Technicians tested the paralleling circuit after replacing a generator to confirm even load sharing.
