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 ...
A branch type AFCI trips on 75 amperes of arcing current from the line wire to either the neutral or ground wire. A combination type adds series arcing detection to branch type performance. Combination type AFCIs trip on 5 amperes of series arcing. Dual-function AFCI GFCI (ground fault circuit interrupter) 110 volt receptacle circa 2016
An automatic trip is an action performed by some system, usually a safety instrumented system, programmable logic controller, or distributed control system, to put an industrial process into a safe state. It is triggered by some parameter going into a pre-determined unsafe state.
Older models of PASS devices required manual arming by firefighters prior to entering a dangerous environment. The unit was equipped with a key which, when removed, armed the unit. This key was left outside the hazard area with an entry control officer. When the unit activated, it could only be switched off by inserting this key.
A shunt-trip unit appears similar to a normal breaker and the moving actuators are ganged to a normal breaker mechanism to operate together in a similar way, but the shunt trip is a solenoid intended to be operated by an external constant-voltage signal, rather than a current, commonly the local mains voltage or DC. These are often used to cut ...
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.
A security alarm is a system designed to detect intrusions, such as unauthorized entry, into a building or other areas, such as a home or school. Security alarms protect against burglary ( theft ) or property damage , as well as against intruders.
Honeywell Gent, formerly Gents' of Leicester, is a British manufacturer of life safety equipment based in Leicester, England.Established by John Thomas Gent, the company is thought to have started in 1872 however it could have been trading as early as the 1860s. [1]
