An electrical safety device that instantly shuts down a circuit if leakage occurs, greatly reduces the risk of electrical shock. These devices commonly are built into outlets and usually are required by code for outdoor receptacles.
A device that instantly breaks the circuit when a short develops. Required for outlets that are used in bathrooms, kitchens, outdoors or wherever electrical equipment might come into contact with water.
A safety device that senses any shock hazard and shuts down a circuit or receptacle. Home Improvement Encyclopedia
Electrical device that safely cuts the electrical power in the event of a short circuit or excess current going to ground. Prevents electrocution accidents.
A device which automatically opens the circuit when it senses a current leak to ground. Designed to prevent personal injury when electrical equipment is operated, it is particularly helpful in a damp or wet environment.
Provides the best available protection against severe shock and electrocution. A GFCI device will de-energize a circuit when it senses a difference in the amount of electricity passing through the device and returning through the device, or a "leak" of current from the circuit.
A safety circuit breaker that compares the amount of current entering a receptacle on the hot wire with the amount leaving on the white wire. If there is a discrepancy of 0.005 volt, the GFCI breaks the circuit in 1/40 of a second. Usually required by code in bathrooms, kitchens and outdoor areas that are subject to dampness.
A device intended for the protection of personnel that functions to de- energize a circuit or portion thereof within an established period of time. It is activated when a current difference between the neutral and hot conductors exceeds some predetermined value that is less than that required to operate the over current protective device of the supply circuit. The current difference is usually caused by a current to ground.
Also called a GFCI - A device intended to protect people. It interrupts (de-energizes) the electrical circuit whenever it detects the presence of excess electrical current going to ground (usually 1/40th of a second and 5/1000th of an ampere).
A device that monitors and detects ground faults in a the circuit, functioning to de-energize the circuit or part of a circuit where a fault exists.
