Why is the GFCI buzzing when you turn on the Breaker?
There's a few small parts inside a GFCI and also a small coil of cable. Electricity in an AC circuit can be considered to vibrate in the cables, this produces unnoticeable harmonics (vibrations/noise). However when a coil (cablewrapped around and around) has AC Current flowing through it these harmonics are increased and become noticeable (canbe heard).The noise coming out of your device is not a safety issue, it is not indicative of a fault with your electricity, however it is annoying.I shall now give a couple of reasons why it may be unavoidable.Resonance depends on many things... Materials the board and GFCI are mounted to being one. the overall measurements and position of the GFCI in relation to the materials around it being another. It might be that the board itself is spreading the sound wave.It may even be the tiniest spec of dust inside the GFCI itself, or that the GFCI'smounting bracket is a tiny bit loose.You may find you can slide The GFCI to one side or another, space permitting, inside your board (youmay have to remove a black plate from the front panel), and by just moving it to one side it may stop the noise all together.A rather unorthodox method of stopping this noise (dueto dust and other internal causes), is to give the GFCI a sharp rap on the front with a solid Item not a heavy item example:Don't use a hammer, also try not to hit the switches). something like a spoon or the handle of a screw driver should do the trick.(Source: Qualified electrician)Otherwise, your looking at maybe calling out an electrician to see if he can find where the sound is specifically coming from, and to put a piece of dampening material into your board.If in doubt, get an electrician out.
How do you install an electric pool pump I've already hooked up the wiring and it's been working fine for three month's. Then the breaker tripped now it keeps tripping when I try to turn pump back on?
=== === Any socket outlets or wiring to pumps, etc must be protected by a GFCI, not only by the main circuit breaker on the house AC power supply panel.Sounds like there is water somewhere in the circuit and that is causing the GFCI to keep tripping every time you press the RESET button. The GFCI is doing its job to protect you and your family from electrocution.Turn off all power at the main panel and then check all wiring, junction boxes, outlets, etc. in the circuit for water. Every part of the circuit must be allowed to dry thoroughly before the GFCI will allow you to reset it. Then be sure to protect any connections in the circuit from getting any water spray or splashes in future.Really this work should be done by a licensed electrician who will know exactly where to check and what to do to make your electric pool pump - and any socket outlets in the same circuit - safe to use in future.Is the distance from the panel to the pool very far or long, A ground fault breaker is looking for a difference in potential the longer the distance the more sensitive they become. What you may have to do is put a ground fault outlet by the pump and put the wiring in a regular breaker. IF YOU ARE 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 would happen if you tried to operate a dc permanent magnet motor from an ac supply?
Apart from a lot of loud humming, the motor would not turn, it would take a lot of current and, if the circuit breaker did not trip to cut the supply of current, it would probably overheat or might even catch on fire.
The transistor acts like a diode and?
Yes, the transistor acts like a diode. That is, essentially, what it does. What it also does, and what give it its added value and ability to amplify, is that the base current causes the collector-emitter "diode" junction to vary in its turn-on characteristic. With this ability, you can control a large current with a small current, and a small delta-current in the base causes a larger delta-current in the collector, the ratio being hFe, hence the term "gain".

Why would a GFCI outlet be buzzing or sparking even after nothing is connected to it?
Some GFIs have an audible alarm and buzz when they trip. Answer I have found that a GFI that has been painted over or corroded stuck will cause a buzz when it is overloaded and trying to trip. The problem is when it is painted over and seized open it cannot trip and causes a buzz. I would first start by having the GFI that is closest to the problem switch replaced then check the switch again. If you have any other questions please feel free to email tom@evecasino.com
When the test button is pressed on a gfci outlet it sparks and trips two breakers in the main panel What could be the problem?
The test button should only trip the GFCI. The fact that it is tripping two breakers indicates that somehow both breakers are feeding your GFCI circuit. I have seen this when there was a wiring error and two circuits were joined in an outlet that was connected to a breaker and through the GFCI outlet. To troubleshoot determine which outlets are effected when both breakers are off. Pull outlet from box and if there are two feeds remove one from outlet and run a toner on wire left on outlet to panel and one off outlet to panel. The GFCI could block the toner so if one side of the outlet does not tone back to panel check at GFCI. There must be two paths to your electric panel for the two breakers to trip and the GFCI may be faulty as well. Another way to check is to have the GFCI reset and both breakers on. Check each outlet that you have identified as being on GFCI noting that they can be in different rooms. With all outlets working turn off one of the tripped breakers. See if any outlets so off. If not turn off the other breaker and turn on the first breaker. If power is still present then the outlets are being fed by both breakers.
Can you install an electrical switch before a gfci?
Yes! you can install an switch a head of a GFCI receptacle. This installation is common in some applications to turn on an outside receptacle to control Christmas lights.
How do you test and reset a GFCI receptacle?
GFCI (Ground Fault Circuit Interruptor) A GFCI receptacle can be tested with the built-in test button, which will cause a small ground fault, tripping a properly working device. GFCI receptacles should be tested monthly. GFCI receptacles can also be tested with a plug-in type GFCI tester. This tester has a GFCI trip button on it which accomplishes the same thing as the built-in test button. Your local inspector will usually test with this method. If your receptacle is tripped, it should reset by pressing in the reset button. If it doesn't, the device is wired incorrectly, has a faulty load plugged into it, or is simply in need of replacement. ---- 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.
How do you reset the gauge cluster on 1999 dodge neon?
Turn the car to the on position. Hit trip reset button until it say trip. Now turn the key to off. Hold the trip button and turn to on. Release trip button after the needles reset.
Why does a light turn when you place black to black and white to ground wire?
You don't say "turn off" or turn on". Light should be connected black to black and white to white and ground to ground. If you connect white to ground it will work, but you are then using the ground wire for an unintended purpose. Neutral is bonded to Ground at the panel. Current on ground wire could cause ground loops and may cause GFCI to trip if you have them in your house.
What is the proper way to test a receptacle?
The simplest way to test a receptacle is to use a plug-in type receptacle tester. This tester indicates either proper operation or common miswirings of the receptacle. If the receptacle is a GFCI, there is a special type of plug-in tester that has a GFCI trip button on top. This tester indicates the same things as the other one. In addition, you can press the test button to create a small ground fault, which will trip a properly operating GFCI. ---- IF YOU'RE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do any work yourself, always turn off the power at 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.
The GFCI outlet's reset button does not pop out when the test button is pressed it is already out and when I try to press it in it will not catch although it does have power?
This indicates either you have an active ground fault or the GFCI is bad. To check this out turn off power at breaker and remove GFCI outlet from wall box. Determine if it is powering other non-GFCI outlets. (It will have both input and output wires. If there are output wires remove them and check the outlet again with power and see if it resets. If it does you have a ground fault down the line somewhere. If it still doesn't work you likely have a bad GFCI.
Can you plug a GFCI plug into an extension cord?
If this question is asking if, by using a GFCI, you can protect some equipment controlled by an existing switch, the answer is Yes. My first guess would be that you probably don't need to. A switch that is controlling lighting in an area with a GFCI, such as a bathroom, should - if it was installed correctly - already be controlling a proper lighting fixture. By this I mean if the fixture is above the shower it will be of a type that is safety-listed 'for use in wet locations'. That type of light fixture does not need to be protected by a GFCI since it is designed for use around water. How to feed a switch from a GFCI: Without GFCI protecting the switch: Connect a hot (usually black) wire from the "LINE" side of the GFCI (which will be marked) to one brass screw of the switch. (Assumption is single pole switch.) Connect another hot wire from the other brass screw of the switch to the light fixture or load's hot wire. Connect a neutral (white or gray) from the LINE side of the GFCI all the way to the load neutral without stopping anywhere. Connect all grounds. To GFCI protect the switch: The procedure is the same except you will use the hot and neutral from the "LOAD" side of the GFCI. This will cause the GFCI to interrupt power should a ground fault occur on the switched load. 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 do you install a new range receptacle?
A new outlet (running new wire) or replacing an old one (wires already there)? Shut off the Power to that Receptical, diconnect the receptical, and reconnect the New receptical using the Wires from the one you replaced. Then turn the power back on and Test it with a Tester!
Reset service interval Golf 4?
* Turn on ignition. * Hold down Right trip button and continue to do so whilst turning off ignition. * Still with Right trip button held down turn ignition back on. * Release Right trip button. * With ignition still on turn Left trip button to the Right and release. * Turn off ignition.
Can you put a GFCI into a circuit with an existing GFCI and what will happen if the two GFCIs are in a series circuit?
Note: The latest types of Ground Fault Circuit Interruptor (GFCI) are also called Residual Current Devices (RCDs)."Can you put a GFCI into a circuit with a GFCI?" is probably the same question as "What if two GFCI are in series in a circuit?" and the answer is that one GFCI will most likely trip earlier than the other to break the circuit. Which one will trip first depends on the actual difference in sensitivity between the two GFCIs. Leakage currents are measured in mA (1 mA = 1 thousandth of an Ampere) and GFCIs are designed to trip at a certain leakage current with a tolerance of say + or - 3%. So if the basic trip current was 20 milliamps one GFCI might trip at 19.4 mA and the other at 20.6 mA and they would both be within the design specification. The one that trips at 19.4 mA would be expected to trip first. This question requires answering by a VERY knowledgeable electrician, or an electrical engineer. I am neither, but until the right answer comes along, I will attempt to provide some information which hopefully will allow a better understanding of the issues involved. A GFCI [ground fault circuit interrupter] is much different from, although similar to, a circuit breaker. The DIFFERENCE is WHAT they are designed to detect and react to. The purpose of a fuse or circuit breaker is to detect excess or MASSIVE current flow [ie. a SHORT CIRCUIT, a direct short to ground], and then very quickly turn off the electrical current to the circuit, in order TO PREVENT a FIRE. This is the only thing the breaker is designed and intended to do. This limited capability will not prevent a person from being electrocuted when a fault occurs within an electrical device, if the current flow happens to be low. Voltage and current faults which can kill a person usually will not be detected by a circuit breaker. A ground fault circuit interrupter [GFCI], on the other hand, is designed to, and will, detect those low level currents which can kill a person, BUT which are not great enough to trip a breaker. When a GFCI detects potentially dangerous current it, like a breaker, trips in order to open the circuit. Now as to WHY, when you placed two GFCIs in series [one in the breaker panel feeding one in an electrical receptacle], the first GFCI tripped when the second GFCI is "tested." When you press the TEST BUTTON on a GFCI it puts a high resistance load on the circuit, which simulates a "small" ground fault, and I think both GFCIs "see" the same fault and react as designed and intended. Again, a true professional should "bless" my comments, but I think that there is no danger or hazard in placing two GFCIs in series. On the contrary, I think there is redundant capability in the pairing, with the first GFCI functioning with, and as a backup to, the second. I suggest you contact your local electrial inspection department regarding what the code(s) say about this issue, and also call the tech support people at the 800 number on the packaging for the GFCIs. Another source of information is a local electrical engineer, if you know someone who can help you make contact. Until a more informed answer comes along, I hope this helps you to understand the issues involved. 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.
