Screw driver accidentally touched ground wire while screwing a hot black wire in the light switch box. The power went out but the circuit breaker did not trip. Can you tell me how to fix it?
If you didn't burn the wire off then the breaker did trip. Sometimes a tripped breaker is hard to see. Go down the whole panel switching each individual breaker off and then on again. This should rectify the problem. A word from the wise, I have been an electrician for 42 years and always shut the power off before working on equipment.
What function does a circuit serve in your home?
it runs electricity to different rooms and regulates it. Has a max capacity and when reaches it it will trip or break. then you go to the Breaker and switch it back.
Can a circuit breaker go bad just by turning it off and on?
A breaker is a mechanical device and certainly would wear some with manual on and off usage, but it should be minimal and should not cause a problem unless it were defective. There are many commercial applications where the breaker is used for daily on/off use for lighting and other functions. The breaker can fail by having a mechanical part malfunction or perhaps arcing between contacts that would corrode or fuse mechanical contacts.
What makes a circuit breaker go bad?
A circuit breaker can go bad from being tripped too many times. Many people don't understand that the tripping of a circuit breaker indicates a problem that needs to be corrected. They usually just reset the circuit breaker, leading to a very common second (or third, or fourth) trip. Circuit breakers tripping are for the prevention of fire due to excessive heat in the circuit. They're not supposed to be tripped repeatedly. This can wear the breaker out. Believe it or not, I've also seen circuit breakers fail to re-energize after being turned off. I speculate this was actually caused by the breaker never having been cycled (it was a main breaker), and the time elapsed since it was installed. Electrical equipment doesn't last forever. It's the same as anything else.
Is it safe to go from 12-3 wire to a 14-2 wire in the middle of a switch leg?
No. The wire size is dependent on the circuit protection. If the circuit uses a 20 amp breaker you need to run 12 AWG wire on all devices connected to that circuit.
Do some electrical breakers when they are tripped go into the off position instead of the normal tripped position I have a cutler hammer breaker that tripped but is in the off position?
Yes, some electrical breakers can move to the off position when they trip. This is a safety feature to indicate that the circuit is no longer functional. To reset the breaker, switch it back to the on position, then to the off position before resetting it to on. If the breaker continues to trip, there may be an underlying issue in the circuit that needs to be addressed.
Why is the power off on on breaker when it is not flipped off?
Turning the breaker on allows the power to flow through to the outlets, lights, and appliances on that circuit, so yes power goes to and through a turned on breaker. If the breaker is off, but the main power is on, power still get to the breaker, usually from the bus bar that runs down the middle of the back of the breaker box.
Why do the windshield wipers go on and off 1996 Dodge Grand Caravan?
The wiper motor has a switch inside of it. When they are turned off and the wipers go to the down position it trips the switch in the motor that tells the computer they are in the down position. If that switch in the motor is faulty, the wipers are repositioning until the switch is tripped to the off position. THE FIX.... Replace the wiper motor.
If a shunt trip occurs does breaker go to off or trip position?
When a shunt trip occurs, the breaker typically goes to the "trip" position, which indicates that the circuit has been interrupted and the contacts are open. This allows for quick identification of the issue and isolation of the circuit for safety reasons.
If your circuit breaker popped and will not go back what should you do?
first be sure to reset the breaker handle to the off position. When a breaker trips the handle goes to a neutral position. After resetting the handle turn it tothe on position. If it trips again there is a short in the circuit. Find out which outlets are not workingand unplug anything that is currently plugged in to the outlets. Reset the breaker and turn it to the on position,if it trips again call a qualified electrician.
How do you reset breaker?
Go out to your breaker box (usually in the garage or in the basement), open the cover and look down at all the switches. One or more of them has been switched off. Flip it back to its on position.
When does the APU door open light go off for KC-10?
approx 60 sec after start switch is in the off position
What is wrong with your air conditioner if the fan is blowing but the compressor is not working?
It is possible that the circuit breaker for the compressor unit is thrown (switched to "off"). Go outside to the compressor unit and follow the big cable up to the circuit breaker panel on the wall. If it is off, throw the switch to "on." If that is not the problem, something is probably wrong with the compressor unit. Turn off the breaker panel and call a repairman.
When you open the switch what happen to the bulb?
If the switch is in the off position, the circuit will be broken and the electric current can't flow to the bulb, so the bulb will not light up.
Why does the bulb go out when you open the switch?
It is time to change the switch for a new one. Switches only last so long being turned on and off on a daily basis. Their mechanical parts get worn and the internal blades that open and close the circuit get loose. Time for a new one. Shut the power off at the breaker and exchange the wire positions one at a time to exactly the same position on the new switch.
How would you turn off the main circuit breaker?
This is relatively easy if you are careful. However, you could kill yourself if you are not careful. Safety gear such as insulated rubber gloves, eye protection and rubber sole shoes all provide a margin of safety. Also have someone standing by to drag you away from a live circuit if you happen to get in trouble. Tie a rope to your belt for example. Now turn off breaker you are replacing. remove front panel of electric panel taking care not to touch anything inside panel. Once the panel is removed you expose live surfaces and wires. Make sure breaker is off. If in doubt check output with a volt meter. Put one hand behind your back and with a screwdriver in your other hand unscrew the screw holding in the black wire. Pull the black wire away from the breaker and make sure you don't touch it to any live black wires or the hot buss bar. Usually the breaker will pull out from the side away from the center of the electric panel. Usually there is a "c-shaped" clamp that clamps onto a retaining bar and another clamp on the hot buss bar. Lift breaker away from box. Insert new breaker and reconnect hot. Make sure breaker is off while re-inserting hot wire.
How do you get key to turn to lock position will turn on engine but cant go to lock key stuck car off in 2007 Kia Spectra?
Make sure that the sterring colum is not in a bind all so see if you have a switch release on the side of the sterring colum and depress and turn the switch to off position make sure the switch has a release lever on the side of the sterring colum if so depress it and turn off the switch
