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.
Double-stack rail transport is a form of intermodal freight transport in which railroad cars carry two layers of intermodal containers. Invented in the United States in 1984, it is now being used for nearly seventy percent of United States intermodal shipments.
Double stack may refer to: Double-stack rail transport — trains with two layers of containers. A guitar amplifier configuration; Dual IP stack implementation, in ...
Fusebox, or variants, may refer to: Fuse box, or distribution board, in electric wiring; FuseBox, a brand of distribution boards and related products;
These circuit breakers contain so-called arc chutes, a stack of mutually insulated parallel metal plates that divide and cool the arc. By splitting the arc into smaller arcs the arc is cooled down while the arc voltage is increased and serves as an additional impedance that limits the current through the circuit breaker.
−6% of 230 V, meaning anything between 216.2 and 253.0 V is acceptable; and furthermore because prior to the introduction of this standard the previous standard had been 240 V, or more specifically 240 V ±6% (225.6–254.4 V), which almost perfectly falls within the new standard, so distributors lacked sufficient motivation to change the ...
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.
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 ...
