You may need to first switch it on before off.

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.
If a shunt trip occurs does breaker go to off or trip position?
the breaker goes to trip position
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?
Some breakers can trip totally off. If the breaker is continually turning off without a wiring issue, then the breaker could be going bad.
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.
What might cause power to go off and on in the second floor when nothing is on but not in the first floor and the breaker is not tripped?
Call an electrician quick- and switch off the breaker for that circuit. It sounds as if there is a loose connection somewhere, and possible fire hazard.
Why would Window AC unit and TV go out checked breakers all ok switched breaker on and off still nothing overhead light in room is working any idea?
If A/C unit and TV are on the same circuit it sounds like a breaker trip. If it is not evident which breaker tripped move all of the breakers off one at a time. Move completely to the off position. You should come across one that clicks when moved to the off position. This is the tripped breaker.
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.
Why did electricity along the line go out when switch was turned on?
Bad switch or a short and tripped the breaker.
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.
When does the APU door open light go off for KC-10?
approx 60 sec after start switch is in the off position
Is it difficult to differentiate a SPST switch from a SPDT switch?
No it is not hard to tell them apart. A Single Pole Single Throw switch will go directly from the on position to the off position breaking the circuit. This is the type of switch that is used in homes for lighting control. A Single Pole Double Throw switch will usually have a stop indent which is the off position mid way through the throw. This is the switch that is used for a transfer switch when using a stand by generator in the system. The full up (on) position is usually connected to utility power. The full down (on) position is usually connected to the stand by generator.
