Glossary of Terms

Industrial Control Panel - An assembly of a systematic and standard arrangement of two or more components such as motor controllers, overload relays, fused disconnect switches, fuses, and circuit breakers and related control devices such as pushbutton stations, selector switches, timers, switches, and control relays with associated wiring, terminal blocks, pilot lights and similar components.

Interrupting Rating - The highest current at rated voltage that a device is intended to interrupt under standard test conditions.

Short-Circuit Current Rating – The prospective symmetrical fault current at a nominal voltage to which an apparatus or system is able to be connected without sustaining damage exceeding the defined acceptance criteria

Control Circuit – A circuit that carries the electric signals directing the performance of a controller, and which does not carry the main power circuit. A control circuit is, in most cases, limited to 15 amp.

Power Circuit – Conductors and components of supply, branch, and feeder circuits, supplying main line power to loads such as heaters, motors, lighting, receptacles, power transformers, and appliances.
