Electrical cabinets and enclosures protect and organize switchgear, controls, terminals and wiring. Material, ingress protection, heat removal, internal separation, cable entry and maintainability must be selected from the equipment and environment, not appearance. For related planning, see the distribution panels…

An electrical low voltage distribution board receives power from an upstream source and divides it into protected outgoing circuits. Depending on size and standard, the equipment may be called a panelboard, distribution board, switchboard, main low voltage distribution board or…

A 125V DC distribution panel distributes branch circuits from defined positive and negative DC rails. The panel rating, feeder, return conductor, grounding, breaker family, available fault current and enclosure must all be verified. “125 V” describes the nominal circuit voltage;…

A calculator for power factor supplies reactive power close to an inductive load, reducing the reactive current drawn from the utility. Correctly applied, a capacitor bank can lower current, release transformer and cable capacity, reduce losses, and help avoid utility…

A 120V AC distribution panel distributes single-phase branch circuits from a defined line-to-neutral or line-to-line source. The panel rating, feeder, neutral, grounding, breaker family, available fault current and enclosure must all be verified. “120 V” describes the nominal circuit voltage;…
