The measures were brought into legal effect by the Minister for Health with the COVID-19 (Temporary Measures ...
Consumer unit. Electrical switch. Earthing systems. v. t. e. 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 ). Its basic function is to interrupt current flow to protect equipment and to prevent fire.
The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter ( AFCI) or arc-fault detection device ( AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can ...

Residual-current device. Distribution board. Consumer unit. Electrical switch. Earthing systems. v. t. e. A residual-current device ( RCD ), residual-current circuit breaker ( RCCB) or ground fault circuit interrupter ( GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is ...
Stab-Lok is a brand name of electrical circuit breakers that were manufactured primarily by Federal Pacific Electric between 1950-1980. [1] [2] In June 1980, Reliance Electric, which had purchased FPE, reported to the United States Consumer Product Safety Commission that "many FPE circuit breakers did not fully comply with Underwriters ...
An earth-leakage circuit breaker ( ELCB) is a safety device used in electrical installations with high Earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use residual ...
