| Cabling
|
The twisting together of two or more insulated conductors to form a cable. |
| Capacitance |
The ability of a dielectric material between conductors to store electricity when a difference of potential exists between the conductors. The unit of measurement is the farad, which is the capacitance value that will store a charge of one coulomb when a one-volt potential difference exists between the conductors. In AC, on farad is the capacitance value that will permit one ampere of current when the voltage across the capacitor changes at a rate of one volt per second. |
Circuit (Electric) |
The complete path of an electrical current. When the continuity is broken, it is called an open circuit; when continuity is maintained, it is called a closed circuit. |
| Clamp |
Permanent deformation of the insulation due to mechanical force or pressure (not due to heat softening). |
| Cold Flow |
A standard system for designating wire diameter. Also referred to as the Brown and Sharpe (B&S) wire gauge. |
| Color Code |
A system for circuit identifaction through use of solid colors and contrasting tracers. |
| Compound |
An insulating or jacketing material made by mixing two or more ingredients. |
| Concentricity |
In a wire or cable, the measurement of the location of the center of the conductor with respect to the geometric center of the surrounding insulation. |
| Conductor |
An insulated wire suitable for carrying electrical current. |
| Contacts |
The parts of the connector that actually carry the electrical current, and are touched together or spearated to control the flow. |
| Continuity Check |
A test to determine whether electrical current flows continuously throughout the length of a single wire or individual wires in a cable. |
| Cord |
A flexible insulated wire. |
| Corona |
Ionization of air surrounding a conductor caused by the influence of high voltage. Causes deteriorization of insulation materials. |
| Crazing |
The minute cracks on the surface of plastic materials. |
| CSA |
Abbreviation for Canadian Standards Assocation, a non-profit, independent organization that operates a listing service for electrical and electronic materials and equipment. The Canadian counterpart of the Underwriters Laboratories. |
Current Carrying
Capacity |
The maximum current an insulated conductor can safely carry without exceeding its unsulation and jacket temperature limitations. |
