Where would you find or use an earth leak circuit-breaker?
Proper name is GFCI (ground fault circuit interrupter). It could be a breaker or receptacle. It's used for wet location circuits, like bathrooms, kitchens, hot tubs, outdoor
Arc-fault circuit interrupter trouble shootting?
The test is, push the button, if the breaker trips, tested ok, if not,the breaker is bad,(rare) or if it does not reset, somewhere in the house, hot is connecting to neutral. Bad outlet or even light fixture. Arc-fault are used in bedrooms. Codes in most areas. These are in case the kids stick a fork into an outlet. Ground fault is used near water.
How does a ground fault circuit interrupter shuts down a circuit?
A ground fault circuit breaker detects leakage current between the hot wire coming off the breaker and the neutral/ground since the neutral is bonded to the ground in the panel, if it senses a current of 6 milliamps or more it will trip. Note: no sharing of the neutral for a circuit on a ground fault breaker If a few milliamps from the hot (black) wire do not return on the neutral (white) wire, then a GFCI assumes that current it traveling harmfully elsewhere through your body. So it disconnects. A GFCI can monitor 15,000 milliamps. But if only 5 go missing, then a GFCI trips.
What is ground fault protection?
GFI's (Ground Fault Interruptors) measure the difference between the hot conductor current and the neutral current. In a normal (no fault) circuit, every single milliamp of current flowing out of the hot should return through the neutral. In other words, the two currents should be equal. If there is a ground fault, at least some of the current flows from the hot. through the fault path, to ground. In this case the neutral current is less than the hot current by however much is flowing to ground. The GFI senses this difference and trips, opening the circuit. GFI's are designed to protect equipment from damage and trip at around 30 ma. of differential current. GFCI receptacles (Ground Fault Circuit Interruptors) like the ones you might find in your bathroom, and GFCI circuit breakers are designed to protect people, and trip much lower, around 5 ma.
What is ground fault in the NEC book?
A ground fault is where there is unexpected current on ground. It represents an imbalance between (hot) current supplied and (neutral, or opposing hot) current returned. That imbalance, by Thevanin's current law, must mean there is current on ground.Usually, a ground fault represents a malfunction or short in the load. Sometimes, it represents a cross tie or interchange of ground and neutral. In any case, a ground fault must be corrected, because it represents an unsafe condition, and because the NEC requires such correction.Some times this is a bit tricky to see, since neutral and ground are tied together at the distribution panel and at the service transformer. Since the NEC, however, requires isolation between ground and neutral except at the panel, detecting ground fault is somewhat straightforward, usually measured with a differential current transformer, comparing hot and neutral or opposing hot.I do not have a copy of the NEC in front of me. This is an intellectual answer, but I believe it to be consistent with the NEC's formal definition of a ground fault. Please, anyone with the formal definition, feel free to refine this answer.
How a 240 V GFCI breaker works without a neutral ran to the equipment?
A 240V GFCI breaker monitors the difference in current between the hot wires, providing ground-fault protection without needing a neutral wire. It compares the current on both hot wires and trips if an imbalance is detected, indicating a ground fault. This system does not rely on a neutral wire to detect faults and protect against electrical shocks.

What is A ground-fault circuit interrupter?
== == If the current in an ac power circuit is not balanced between hot and neutral, possibly meaning some of the current is going through a human being to ground, a GFCI breaker or receptacle will break the circuit to keep the person from being electrocuted.
How do you change one breaker on a 3 wire that feeds two regular circuit breakers to a single arc fault circuit breaker - or do you have to change both breakers to arc fault so each has a neutral?
In order to properly convert a circuit to an arc fault circuit breaker, both the hot and neutral wires must be connected to the arc fault breaker. This means that you would need to change both breakers to arc fault breakers, as each would require its own connection to the neutral wire to function effectively and meet safety standards.
Why tap in your house gives shock when it is touched or used?
Your water system is not grounded. Turn the main breaker in your distribution panel to off and ground the water system. If a "hot" wire has come into contact with the plumbing, when you turn the electrical panel main breaker back on a breaker will trip. This will give you the circuit that is at fault and a place to start looking for the short circuit.
Why is the ground wire hot at all outlet boxes on a particular circuit?
Most likely the ground (green) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! Possibly you meant the neutral wire not the ground wire, in that case most likely the neutral (white) wire is mistakenly connected to hot instead of the hot wire (black) at the breaker panel! In either case check all three wires in the breaker panel for that circuit to make sure they are all correctly connected! Black is hot, White is neutral, Green (or uninsulated in some cases) is ground.
Why not hook ground to neutral since they are hooked on same spot in breaker box why not in outlet box.?
The "hot" wire and the neutral wire both carry current (the same amount, in fact) when a load is connected to complete the circuit. The ground wire never carries current except when a fault-to-ground situation occurs. Yes, neutral and ground wires should both be at ground potential, but NO they should not be connected at the outlet.
When a GFCI senses a fault the ground-fault current can originate from what either the hot or neutral wire on the line side of the GFCI either the hot or neutral wire on the load side of the GFCI?
Yes, a ground-fault current can originate from either the hot or neutral wire on the line side of the GFCI, or from either the hot or neutral wire on the load side of the GFCI. This is because the GFCI monitors the difference in current between the hot and neutral conductors, tripping when an imbalance is detected.

How does a three pronged plug help you from getting electrocuted?
The ground prong connects to the metal case of the appliance so that if there should be an internal wiring fault that connects the "Hot" side of the house voltage that it will immediately short to ground, which will let a large amount of current to flow and cause the breaker to trip; rather than float and let a person touch the case and become the ground and get a shock.
