The maximum load that a generating unit, power plant, or other electrical apparatus can carry under specified conditions for a given period of time, without exceeding its approved limits of temperature and stress.
Capability margin
The difference between net electrical system capability and system maximum load requirements (peak load); the margin of capability available to provide for scheduled maintenance, emergency outages, system operating requirements and unforeseen loads.
Capacitance
A measure of the electrical charge of a capacitor consisting of two plates separated by an insulating material.
Capacitance meter
A device for locating moisture within a roof system by measuring the ratio of the change to the potential difference between two conducting elements that are separated by a non-conductor.
Capacitive reactance
Opposition of a capacitor, measured in ohms, to changes in voltage.
Capacitor
An electrical device that adjusts the leading current of an applied alternating current to balance the lag of the circuit to provide a high power factor.
Capacitor start/run
Capacitor start/run is a feature that allows a power capacitor to store electricity and provide an extra boost of power when needed. The result being that the tool draws fewer amps under heavy loads.
Capacity
The load that a power generation unit or other electrical apparatus or heating unit is rated by the manufacture to be able to meet or supply.
Capacity factor
The ratio of the average load on (or power output of) a generating unit or system to the capacity rating of the unit or system over a specified period of time.
Capacity of parties
Legal competence of parties to be held responsible for the terms of a contract or agreement. Underage or mentally incompetent people do not have legal capacity.
