There is only 2 forms of Ground fault protection. A breaker or a recptacle (stadard plugs and outlets). Both are obvious to the naked eye. A recptacle will have a test and reset button that will turn it on and off. This is a sensor that constantly monitors the diffence of potential between the HOT wire and the grounded conductor . If this gets to and unacceptable limit It will trip. The breaker will have a test and reset button next to the switch. The complicated part is that 1 GFI outlet can protect multiple outlets. When it is hooked up it has an option to Downstream other outlets. Theese outlets are then monitored by the same sensor in parralel with the first. The best way is to push the test button and check for outlets that shut of with the GFI. Code requires a GFI protected outlets to have a sticker on it stating that fact. A breaker wll protect the entire circiut from ground faults provided it is hooked up correctly.

In relation to electric what does the term fault protection mean?
Protective devices - relays, CT,PT, isolators, circuit breakers are used for fault protection. Fault protection means If there is a fault in the circuit, the circuit must be cut off before any damage occurs due to fault.
Which electrical protective device is designed to detect a difference in current location in circuit wires?
A) Outlet plug B) Ground-Fault Circuit Interrupter (GFCI) C) Electricity Read Monitor D) Current Path Detector
What is the GFCI?
A "GFCI" is a ground fault circuit interrupter. For more information see the link below.
What does GFCI stand for?
Definicion of Ground fault Circuit Interrupter.
What does the letters GFCI stand for?
Ground-fault circuit interrupter.
Does a ground fault interrupter need to be grounded?
Yes. It is measuring leakage current to ground.
The device used to deenergize circuits automatically when a very small ground-fault flows is the?
Ground Fault Circuit Interrupter (GFCI).
How the earth leakege detectors work?
If you are referring to the "ground fault interrupter", then it works on the principal of what goes in must come out. Current is measured going into the device. As long as the same amount of current returns through the neutral wire, (everything is equal), then the ground fault interrupter remains intact and passes current. If there is more current going into the device than is coming back, it means some of the current is leaking to ground or shorting to ground (possibly through a human body). When this happens, the ground fault interrupter kicks out and cuts the voltage going into the device. You have to manually reset the ground interrupter to make it work again. This way, the ground fault interrupter helps prevent serious injury or death to the possible human that is getting shocked.
What does the term GFCI receptacle stands for?
The term GFCI stands for Ground Fault Circuit Interrupter.
Which circuit breaker use to prevent against electric shock?
GFCI = Ground Fault Circuit Interrupter.
The device used to deenergize circuits automatically when a very small ground fault current flows is the?
A ground fault circuit interrupter is the device used to de-energize the circuit.
What minimum current will activate a ground fault circuit interrupter?
30 mAmp rating devices are commercially available.
How does a ground fault circuit interrupter act like small circuit breaker?
A ground fault circuit interrupter or rcd trips when the is leakage current to ground In no fault condition the active and neutral conductor emf's cancel each other out in ground fault condition the emf's become unbalanced resulting in a small voltage being inducted into a toroidal coil which activates a internal trip relay resulting in disconnection of supply domestic rcd's are generaly set to trip at 30ma to ground
