Will a GFCI outlet trip when the current is reduced or shut off?

The GFCI is measuring leakage current to ground, so if no current is flowing it won't trip.

How do you determine if an outlet is after or before the gfci?
GFCI receptacle has the ability to protect all receptacles down stream from the device. One way to see what is on the circuit after the GFCI is to trip (test) the device. Every thing that is connected downstream will shut off and there will be no voltage present to test. Any outlets ahead or upstream of the device on the same circuit will not be effected. <<>> Trip the gici. If the outlet goes out it's after, if not, it's before.
What does a GFCI measure?
A Ground Fault Circuit Interrupter (GFCI) measures the amount of current flowing from hot to neutral. If there is an imbalance it will trip and shut of power. It can detect and imbalance of as little as 4 milliamps. It reacts in 1/30 th of a second.
Can you remove an outlet or hard wired fixture from a circuit for troubleshooting a GFCI I that won't reset?
Shut the GFCI off at the panel breaker. You can remove the down stream load right at the GFCI. Then reapply the power and keeping your fingers clear of the wire terminals, trip the GFCI and reset it. If it stays reset the trouble is down stream from the GFCI. To trouble shoot down stream remove all plugged in devices and try a reset. If still no reset remove the hot wire in the hard wired fixture and try for a reset. If still no reset buy a new GFCI.
What causes a GFCI outlet to trip the dryer is hooked to a GFCI outlet and it keeps tripping you reset it and it works again then it trips again any suggestions?
The key to this situation is to establish whether it is the receptacle or the ( I am presuming a hair dryer and not a clothes dryer). If you have another dryer plug it into the receptacle and see if it also trips. If you don't have another dryer any appliance will do, fry pan or toaster for example. If the receptacle does not trip then the cause is the hair dryer. If the GFCI trips then it should be replaced. The operation of a GFCI is current in "hot" leg should equal current in the return neutral. Replacement can be done yourself. Shut the circuit off at the electrical panel to kill the electrical circuit and install the new one exactly as the old one was wired. P.S. Clothes dryers do not need to be connected to a GFCI breaker. <<>> Your gfci is trying to tell you that in all probability the dryer is too much of a load for the circuit. Call a good electrician!
When do you need a GFCI breaker?
Answer for USA, Canada and countries running a 60 Hz supply service.GFCI receptacles are required by the US National Electrical Code in locations where water and electricity are likely to come into contact, such as in kitchens, bathrooms, garages, and outdoors. For dwellings (places where people live) the exact places GFCI protection is required are listed in Article 210.8 of the US National Electrical Code 2008:(1) bathrooms(2) garages(3) outdoors(4) crawl spaces(5) unfinished basements(6) kitchens(7) laundry, utility, and wet bar sinks(8) boathousesAs 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.IF YOU'RE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.
What are advantages of gfci circuit breakers?
Advantage #1 - Shock Prevention The most obvious advantage of a GFCI outlet is that it prevents shocks and electrocution. A GFCI outlet has a built-in sensor that monitors the inflow and outflow of electricity from an appliance. For example, if a live wire inside an appliance is in contact with the metallic surface of the appliance, then, you will receive a shock if you touch this appliance. However, if the appliance is plugged into a GFCI outlet, then the GFCI will notice the change in electrical flow occurring as result of the loose wire, and it will immediately shut down the power. Thus, GFCI outlets are necessary for shock prevention. Although they are slightly more expensive than regular power outlets, this massive advantage makes them well worth the additional cost.Advantage #2 - Fire PreventionThe primary function of a GFCI outlet is to detect ground faults. Since ground faults, which occur when the flow of the electrical current leaves a circuit, can cause electrical fires, it is safe to say that one of the advantages of installing a GFCI outlet is the prevention of fires. Although electrical fuses do offer basic protection against electrical fires, when they are combined with a GFCI outlet, you never have to worry about an electrical fire harming your home or workplace.Advantage #3 - Prevention of Damage of Appliances Sometimes, over a period of time, as insulation breaks down, a certain amount of electric current begins to leak into household appliances or other electronic items. If the outer body of the equipment is not made of metal, you may not get a shock, but this constant leakage of current will damage the equipment. In fact, this leakage of electricity is one of the most common reasons why computer hard disk drives fail. With a GFCI outlet, you do not need to worry about this happening. This is because the instant the GFCI circuit detects a leak, it will shut down the circuit. This can help prevent expensive equipment and appliances from getting damaged due to electrical leaks.

What is distribution box?
An ELCB (Earth Leakage Circuit Breaker) distribution box is a type of electrical box that is used for electrical GFCI (Ground Fault Circuit Interrupter) outlets. This is the type of outlet that requires a three-prong plug in, one wire of which is grounded. GFCI outlets are set up so that if there is a circuit overload, the outlet is shut off until it is reset, manually.

What is the terminology GFI?
GFI (or GFCI) is an acronym for Ground Fault (Circuit) Interruptor. Essentially, it is a current sensor. A GFI outlet or breaker monitors the current flowing through both the hot and neutral wires. If there is a difference between them, that means electricity is leaving the normal circuit and is flowing through something else (probably you). The GFI watches for this difference and shuts off power to the circuit if an imbalance is detected. This is why a GFI is mandatory for pools, bathrooms, etc.. If you happen to become a conductor because you are wet, the GFI will detect the current flowing through you and shut the power off. A normal breaker will only shut off if your body happens to overload it, which is unlikely.

If you have a 240V outlet for a window AC unit can you connect a switch to shut the outlet off?
Yes, just make sure it is a 220 volt switch.
The dc output of a controlled rectifier is controlled by?
A: An SCR does not produce DC per say but rather is the result of rectification. THE GATE will turn on the SCR when there is enough current available on the SCR. The SCR will not however shut of when the gate potential is reduced or removed. the two way to shut off an SCR is by removing the gate potential AND reducing holding current OR inverting the potential on the anode
Does your PC really turn off when you shut it down?
No. Not until you unplug it from the wall outlet, anyway.
