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".
4 fluorescent lights won't come on and 2 other fixtures do what causes this?
A. no power to the fixture that won't turn on. B bad electrical connection. c. burned out fluorescent lamps d. bad lamp holders e. bad ballast f. etc.
How do you determine if a GFCI is bad?
To determine if a GFCI is bad, you can press the "test" button on the device. If the reset button does not pop out or if the power does not turn off, the GFCI may be faulty and should be replaced.
How do you install a GFCI breaker?
To install a GFCI breaker, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the circuit breaker you want to replace with the GFCI breaker. Disconnect the wires from the existing breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
How to install a GFCI breaker in a circuit?
To install a GFCI breaker in a circuit, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the circuit breaker that needs to be replaced with the GFCI breaker. Disconnect the wires from the existing breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover.

To wire a GFCI breaker, first turn off the power to the circuit. Then, connect the hot wire to the breaker's terminal, the neutral wire to the neutral bar, and the ground wire to the ground bar. Finally, turn the power back on and test the GFCI breaker to ensure it is working properly.
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 sparking and tripping of two breakers in the main panel could indicate a wiring or grounding issue within the GFCI outlet. It's important to have a qualified electrician inspect and repair the outlet to prevent any potential hazards or damage.
