The ground ('earth'), because of its mass, is a reasonably-good conductor and is used as a 'reference' for a distribution transformer's neutral terminal. A ground fault ('earth fault') occurs when the line conductor from the distribution transformer makes accidental contact directly with the ground ('earth'). The resulting low-resistance earth path back to the transformer's neutral is such that the resulting ground-fault current('earth-fault current') will operate the transformer's overcurrent protection device (e.g. fuse).

What is the GFCI?
A "GFCI" is a ground fault circuit interrupter. For more information see the link below.
Which fault moves ground horizontally?
I am sure that the anwser is the San Andreas fault.
What is phase to ground fault?
There will a only one phase on home electricity.AnswerThere is no such thing as a phase-to-phase-to-ground fault'; the correct term is 'line-to-line-to-ground fault. It occurs when two or more line conductors make contact with each other and to ground; for example, when a JCB accidentally cuts through a three-phase cable.
A large crack in the ground is a?
A large crack in the ground is called a fault which is caused by and earthquake.
What neutral ground resistor?
Neutral Ground Resistor is using for minimizing the fault current of system. It is a resistor which connected between ground and neutral and increase the resisting path for fault current.
What is the GFCI?

How do you wire a ground fault switch?
To replace the wire ground fault switch, you need to switch off electric power from the source. After switching it off you can use the screwdriver to open screw and remove the faulty switch and replace it with a good one. <<>> There is no such a device as a ground fault switch. There is a ground fault breaker and a ground fault receptacle.
What do ground fault relays do?
Ground fault relays sense ground faults in the circuit and trigger a circuit breaker to trip off
What are the types of faults in ehv transmission lines?
The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault
What kind of screws are ground screws?
Ground screws are screws that have been ground into a fine paste in an industrial tumbling machine. They are extremely useful as a grout for tile. the term would apply to the green screw you find in electrical connections they are meant to connect the ground wire which is there to protect you in case of ground fault
Do you need a ground fault breaker for your hot tub?
Yes, the electrical code requires a ground fault breaker for your hot tub.
The device used to de-energize circuits automatically when a very small ground-fault current flow is the?
Ground fault interupter.
What is a difference between ground fault and earth fault?
They mean the same thing, a current to ground/earth that shouldn't exist in the circuit.
The device used to deenergize circuits automatically when a very small ground-fault flows is the?
Ground Fault Circuit Interrupter (GFCI).
What is meant by earth fault protection?
Earth fault protection is called ground fault protection in the US. It is a device that monitors the separation of the hot and ground wires in your house's electrical system. If it detects that the hot and ground have been connected with too low of resistance--like when you drop an appliance into water--it will disconnect the hot line so you won't get shocked. It's not intended to be used this way, but if you want an outlet you can switch on and off and you don't want to pull wire, install a ground fault protected outlet. If you push the "test" button the outlet will be switched off, and pressing the "reset" button turns it back on.
Which fault moves ground horizontally?
I am sure that the anwser is the San Andreas fault.
