Load Calculations - Branch And Feeder Circuits Exam
Questions And Accurate Answers
Ampacity: - Answer The maximum current, in amperes, that a conductor can carry
continuously under the conditions of use without exceeding its temperature rating.
Branch circuit - Answer The circuit conductors between the final overcurrent device
protecting the circuit and the outlet(s).
Continuous load: - Answer A load where the maximum current is expected to continue for
three hours or more.
Device: - Answer A unit of an electrical system, other than a conductor, that carries or
controls electric energy as its principal function.
Individual branch circuit - Answer A branch circuit that supplies only one piece of
utilization equipment.
Outlet: - Answer A point on the wiring system at which current is taken to supply
utilization equipment.
Overcurrent - Answer Any current in excess of the rated current of equipment or the
ampacity of a conductor. It may result from overload, short circuit, or ground fault.
Receptacle: -Answer A contact device installed at an outlet for connection as a single
contact device. A single receptacle is a single contact device with no other contact device
on the same yoke. A multiple receptacle is a single device containing two (duplex) or
more receptacles.
Receptacle outlet: -Answer An outlet where one or more receptacles are installed.
