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.

WILL sink work without the vacuum breaker?
Yes.
What is different Circuit Breker And Isolater?
I think that the questioner is asking what is the difference between an isolator and a circuit breaker.A circuit breaker is a switching device designed to interrupt a fault current.An isolator is not intended to break a live circuit but, rather, to provide a visible separation between a circuit component and live conductors.For example, isolators (or 'disconnectors' in US parlance) are located on either side of a high-voltage circuit breaker. If the circuit breaker requires maintenance, then the procedure is to:a. trip the circuit breaker.b. open the isolators on each side of the circuit breaker, so there is a visible gap between the circuit breaker and the 'hot' conductors.c. apply temporary earths (grounds) between each isolator and the circuit breaker.d. complete a 'permit to work' card.e. begin work.
How do you find out the reason why the motor trips the Ground Fault Circuit Interrupter when starting?
GFI Breakers are designed to an entire system of Receptacle's. they work by tripping any time there is an over load in the system , shorts and quick changes in current. make sure there isn't anything on other receptacle's. still occurs, put the load on it's own breaker..
What will happen if you ground the grounded conductor or neutral at every device?
The ground wire is an important safety wire on an electrical appliance and to work properly it must not be one of the current-carrying wires. That is because under fault conditions there could be transient spikes of voltage on the neutral wire, carried along the supply path, but the earth wire is earthed at the property so this is less likely. Also in many cases the neutral is earthed at the supply transformer and there might be a small voltage between the neutral and earth in the house.
How can a circuit breaker be made to work after it has opened?

WILL sink work without the vacuum breaker?
Yes.
What device senses short circuits and stops electrical flow when ground fault occur?
A Ground Fault Circuit Interrupter (GFCI) is designed to sense short circuits and stop electrical flow when ground faults occur. They work by quickly disconnecting power to prevent electric shocks and protect against fires.
What is a ark fault circuit breaker?
An arc fault circuit breaker is a type of electrical safety device that helps detect and mitigate the risk of electrical arcing in a circuit. It is designed to protect against fires caused by arcing faults, which can occur when there is a loose connection or damaged wire in the circuit. The arc fault circuit breaker will trip and disconnect power when it detects abnormal arcing, preventing potential fire hazards.
What should you do if a circuit breaker feels spongy and won't reset?
If a circuit breaker feels spongy and won't reset, it may be damaged and should be replaced by a qualified electrician. Do not attempt to force the breaker to reset as this can be dangerous. It is important to address the issue promptly to prevent any electrical hazards.
Will a 14-2 gage wire work for a 240 volt 15 amp breaker?
No. You will need a 14/3 with Ground.
I wired into the 20A washer breaker for additional outlet plug for a 15A air compresser but when the washer is turned on the breaker is thrown why and the compressor is not on?
Could be anything at fault. Unplug the compressor and try using your washer. If it works, then you have a fault with your compressor. If it still doesn't work, do what should have been done in the first place: call an electrician.
What happens if only half the outlets work on run the main breaker?
assuming you have reset all of the other circuit breakers as well, look for a ground fault interrupt outled (GFI). It will have a small red and black button in the middle. It will probably be near water, in bathroom kitchen or garage. Reset it and the other outlets should work again.
How does the creep meter work?
A creep meter is a wire stretched across a fault to measure the horizontal movement from the ground.
How does a creep meter work?
A Creep Meter uses a wire stretched across a fault to measure horizontal movement of the ground.
How does a creep-meter work?
A Creep Meter uses a wire stretched across a fault to measure horizontal movement of the ground.
Where do I ground if there is No ground coming out of the box?
The question doesn't say what "the box" refers-to: is it a wall box for a socket outlet or is it for a switch - or is it actually the main circuit breaker panel for the building or apartment?You can add a safety ground wire to any wall box - to connect appliances back to the ground on main breaker panel - only if there is a main grounding wire installed at your main breaker panel.You can't add a safety ground wire to any wall box, to connect appliances back to the main breaker panel, if you don't already have a ground wire installed at your main breaker panel. If that is the case, your wiring must be at least 50 years old. It is time to consult with an electrician...As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
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.
