GFCI circuitry often checks for a difference in current between the ground and neutral?

A GFCI monitors the current in the ungrounded (hot) conductor and the grounded (neutral) conductor. If there is more than 6mA of current difference between the two the GFCI will open the circuit.

Difference between ground and neutral?
As i know,neutral is the return path of current & ground is for any leakage current
What is a ground fault?
difference in current between hot and neutral conductors
Gfci circuitry checks for differences in current between the?
...hot and neutral conductors. (Sounds a lot like a homework question. If so, spend a little more time reading the textbook!)
What is the difference between amphoteric and neutral compounds?
difference between amphoteric solutions and neutral solutions
Will an arc fault breaker work without a ground?
Yes a GFCI will work without a ground wire. A GFCI looks for a current differential between current in on the "hot" wire and current return on the neutral wire. Since current is the same throughout the circuit, no difference, no trip. If the load grounds out or shorts out, the current then takes the path of least resistance through the ground and not the neutral. This creates a difference between the "hot" and return neutral current and the device trips the circuit open.
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.
How does a GTE Sylvania GFCI circuit breaker 1 pole 15 a work?
A GFCI breaker monitors the imbalance of current between the ungrounded (hot) and grounded (neutral) conductor of a given circuit. With the exception of small amounts of leak-age, the current returning to the power supply in a typical 2-wire circuit will be equal to the current leaving the power supply. If the difference between the current leaving and returning through the current transformer of the GFCI exceeds 5 mA (61 mA), the solid-state circuitry opens the switching contacts and de-energizes the circuit. Touch the neutral or hot and you change this current which will trip the breaker.
What is the reason of the existence of a potential difference between the neutral point of the generator and the neutral point of the receiver?
Ground loop current, which is undesirable and every effort should be made to eliminate it.
What is the reading ground to neutral?
Ideally ground and neutral should be at the same potential, but as there is current in the neutral wire and no current (normally) in the ground wire there can be a difference. I have personally measured over 25 VAC on the neutral relative to ground in some systems.
What is difference between ground and neutral?
A neutral is an active conductor in the circuit. It is grounded at the source but that's for another discussion. The ground exists to ensure the proper operation of over current devices like fuses and breakers in the event of a fault.
What is the difference in mass between a neutral deuterium atom and a neutral tritium atom?
1.6749x10-24
What is difference between the mcb and rcb?
MCB stands for miniature circuit breaker , which provides protection against over current. the setting is not adjustable. RCB stands for residual circuit breaker which provides protection against earth fault as well as over current. It monitors the current difference between phase and neutral and if the difference is more than rated value say 200 milli amps it will trip.
