NOTE 1 It is assumed that power distribution equipment covered by the scope of this standard is interconnected to the "outlet" of a "branch circuit" as defined in Section 0 of the CE Code, Part I, and Article 100 of the NEC. In the case of cord-connected equipment, the outlet is the receptacle associated with the building wiring. In the case of permanently connected equipment, the outlet is the interface between the branch circuit conductors associated with the building wiring and the input terminals, pressure connectors, or leads associated with the power distribution equipment covered in whole or part by this standard.

NOTE 2 The following are common definitions of the hardware with related functions that require additional investigation to the appropriate Canadian and U.S. standards:

– Industrial Control Panel: An assembly of two or more components consisting of one of the following:
- power circuit components only, such as motor controllers, overload relays, fused disconnect switches, and circuit breakers;
- control circuit components only, such as pushbuttons, pilot lights, selector switches, timers, switches, control relays; or
- a combination of power and control circuit components.

These components, with associated wiring and terminals, are mounted on or contained within an enclosure or mounted on a subpanel. The industrial control panel does not include the controlled equipment.

– Panelboard: a single panel or group of panel units designed for assembly in the form of a single panel, including buses and automatic overcurrent devices, and equipped with or without switches for the control of light, heat, or power circuits; designed to be placed in a cabinet or cutout box placed in or against a wall, partition, or other support; and accessible only from the front.

– Switchboard: a large single panel, frame, or assembly of panels on which are mounted, on the face, back, or both, switches, overcurrent and other protective devices, buses, and usually instruments.

Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets.

– Transfer switch: an automatic or nonautomatic device for transferring one or more load conductor connections from one power source to another.

– Uninterruptible Power Supply: a power supply used to provide alternating current power to a load for some period of time in the event of a power failure.
