  2. Distribution board - Wikipedia

    en.wikipedia.org/wiki/Distribution_board

    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.

  3. Wiring diagram - Wikipedia

    en.wikipedia.org/wiki/Wiring_diagram

    Architectural style wiring diagram, with lamps and switches shown symbolically in their physical locations on the plan view of the building. Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown ...

  4. Fuse cutout - Wikipedia

    en.wikipedia.org/wiki/Fuse_cutout

    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 ...

  5. Home wiring - Wikipedia

    en.wikipedia.org/wiki/Home_wiring

    Single-phase ~230 V/40 A/9 kW fuse box for apartment rewiring. Each appliance and each room are highlighted into autonomous circuits - this apartment has 14 individual circuits. A relay is used to control the light fixtures in a large room. In new home construction, wiring for all electrical services can be installed before the walls are finished.

  6. Fuse (electrical) - Wikipedia

    en.wikipedia.org/wiki/Fuse_(electrical)

    In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.

  7. Electrical wiring in the United Kingdom - Wikipedia

    en.wikipedia.org/wiki/Electrical_wiring_in_the...

    Such an old fusebox will contain a main switch and a set of fuses, possibly of the re-wireable kind. A more modern consumer unit will contain at a minimum a main switch and an individual miniature circuit breaker (MCB) for each final circuit. Fuses and MCBs are overcurrent devices providing overload, short-circuit and earth fault protection.

  8. Ring circuit - Wikipedia

    en.wikipedia.org/wiki/Ring_circuit

    Diagram of a possible configuration of ring final circuit. Consumer unit is at bottom left. 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.

  9. Residual-current device - Wikipedia

    en.wikipedia.org/wiki/Residual-current_device

    A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
