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.
A fuse can clear a fault within a quarter cycle of the fault current, while a circuit breaker may take around half to one cycle to clear the fault. The response time of a fuse can be as fast as 0.002 seconds, whereas a circuit breaker typically responds in the range of 0.02 to 0.05 seconds.
An electrical junction box (also known as a "jbox") is an enclosure housing electrical connections. [1] Junction boxes protect the electrical connections from the weather , as well as protecting people from accidental electric shocks .
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent).
In 1908, the company was renamed Detroit Fuse and Manufacturing. Horton, an 1895 electrical engineering graduate of the University of Michigan , was credited with the invention of the safety switch, which encased high voltage switches and started the company's main line of business of circuit breakers and encased control panels.

Bare busbars are common, but many types are now manufactured with an insulating cover on the bars, leaving only connection points exposed. In a modern switchboard, the operator is protected from electrical injury by metal-enclosed circuit breakers, switches, and fuses. There may also be instruments and controls for the supply of electricity to ...
Zinsco would remain with copper in both their panels and breakers until the third major copper shortage in the early 1960s, when they would switch to an aluminum bus. In 1963, Zinsco introduced the R-38 twin breaker, which was the only twin circuit breaker that also made contact on both bus-bars for 240 volts in a single breaker space.
An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations to prevent shock. It consists of either a current sensing mechanism, or a voltage sensing mechanism. Such a protection mechanism may be found in the form of distribution board modules, standalone devices, and special sockets (aka receptacles ).
