An electrical distribution device which converts incoming electrical power into several smaller circuits and provides overload protection in the form of circuit breakers or fuses.
In a building, the center of the electrical distribution system.
A wall mounted device that delivers electricity from a supply source to loads in light commercial, commercial and industrial applications.
A wall-mounted electrical power distribution device for use in commercial and industrial applications. It provides circuit control and overcurrent protection for light, heat or power circuits. NEC defines it as a single panel or group of panel units designed for assembly in the form of a single panel; including buses, 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 or partition and accessible only from the front.
The center for controlling electrical circuits.
a lighting or power panelboard, distribution panel, splitter, motor control centre (MCC), transfer switches, fire alarm panels, control cabinet (lighting or power), or switchboard of 750 volts or less. Disconnect switches (fusible or non-fusible), used for local isolation of equipment, will not be charged out as an additional panel; all other disconnect switches will be charged as an additional panelboard.
A single panelboard or group of panel units designed for assembly in the form of a single panel including buses and with or without switches or automatic overcurrent protective devices, or both, for the control of light, heat, or power in a cabinet or enclosure placed in or against a wall or partition and accessible only from the front; also called a Switchboard.
