A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Examples are one design made by MK which has a T-shaped earth pin, and the Walsall Gauge 13 A plug, which has each pin rotated 90°, the latter being in use on parts of the London Underground for 110 V AC supply, [88] [full citation needed] and also in some British Rail [clarification needed] offices for filtered computer supplies.

A house plan [1] is a set of construction or working drawings (sometimes called blueprints) that define all the construction specifications of a residential house such as the dimensions, materials, layouts, installation methods and techniques.
The ring starts at the consumer unit (also known as fuse box, distribution board, or breaker box), visits each socket in turn, and then returns to the consumer unit. The ring is fed from a fuse or circuit breaker in the consumer unit. Ring circuits are commonly used in British wiring with socket-outlets taking fused plugs to BS 1363. Because ...
In electrical distribution, a fuse cutout or cut-out fuse (often referred to as a cutout) is a combination of a fuse and a switch, used in primary overhead feeder lines and taps to protect distribution transformers from current surges and overloads. An overcurrent caused by a fault in the transformer or customer circuit will cause the fuse to ...
A typical one-line diagram with annotated power flows. Red boxes represent circuit breakers, grey lines represent three-phase bus and interconnecting conductors, the orange circle represents an electric generator, the green spiral is an inductor, and the three overlapping blue circles represent a double-wound transformer with a tertiary winding.
Good design practices may segregate, for example, low level measurement or signal cables from trays carrying high power branch circuits, to prevent induction of noise into sensitive circuits. Since wires run in conduits or underground cannot dissipate heat as easily as in open air, and since adjacent circuits contribute induced currents, wiring ...
