The area of a circle with a diameter of one mil (1/1000 inch), used to describe the cross-sectional area of a conductor. One cmil equals approximately 0.0000008 square inches.

The greatest root-mean-square (effective) difference of potential between any two conductors of the circuit.

Circuit-Switchers are multipurpose switching and protection devices. Often used for switching and protection of transformers, single and back-to-back shunt capacitor banks, reactors, lines, and cables. They can close, carry, and interrupt fault currents a

The highest circuit voltage to earth on which a circuit of a transducer may be used and which determines its voltage test.

A device that can be used to manually open or close a circuit, and to automatically open a circuit at a predetermined level of over current without damage to itself.
