Any mechanical device, including switches, can malfunction. You have to be careful wiring up a single pole switch, to make sure it is in the live (positive) line, not in the return (neutral) line.

∙ 15y agoYes, any number of pole breaker is a protective device. The job of a breaker is to protect the wire that is feeding the load from becoming overloaded. This overload protection is provided by a built in thermal trip. Also the breaker has the ability to disconnect the load from a short circuit by using its built in magnetic trip.

Can breaker be bad and still show voltage?
A breaker that still shows full voltage after it has tripped is definitely bad.
The electrical Breaker will not reset?
To reset a breaker move the handle completely to the off position. If it had tripped you will feel a little resistance as it goes to the off position. If this doesn't restore the power the breaker is either bad and in need of replacement, or there is a persistent fault in the circuit causing the breaker to immediately re-trip. Breakers are safety devices.
Can circuit breaker be bad even getting little electricity?
Anything can go bad. A breaker is a mechanical device and can fail for many different reasons.
One of the 120 volt legs in the main breaker has lost power?
check power coming into the breaker if both leads are hot it's a bad breaker
What would cause a short periodic low hum to come from a circuit breaker?
A bad circuit breaker. Replace it.
What does the superstition 'Don't split the pole' mean?
The superstition means that if two people are walking together and come to a pole, if one goes one way around the pole and the other goes the other way around the pole, it will bring bad luck. Both should go the same way around the pole together to avoid the bad luck.
What can cause house electricity to cut on and off?
Loose supply lines on the supply line from the pwr pole connections. Bad main breaker in fuse panel Rare! but loose screw on wire feed in main breaker connection.
How can you tell if a breaker a bad?
Swap it with another like breaker.
How can you tell if a circuit breaker is bad?
Swap it with another like breaker.

How do I repair a Passenger side window that won't operate and the motor is still good on a 97 maxima?
if the the motor is good you need to check the circuit breaker because the circuit breaker might be the problem. window doesnt go bad my dude the motor goes bad check it again
What does the phrase blowing through a pole mean in the pole vault event in the sport of track and field?
It means there is too much energy put in and the pole goes past vertical ( ideal ) position. This isn't a bad thing, it just means you need a pole that is taller or stiffer
Double pole 40Amp breaker on a 240volt disconnet that keeps tripping now why it didn't before?
You didn't say what, if anything was on the circuit. If everything is unplugged from the circuit or disconnected from the circuit and breaker still trips then you have a bad breaker or faulty wiring. If you remove all devices from the circuit and it doesn't trip, you need to find out which device causes the breaker to trip by plugging one device in at a time. If the disconnect controls a single device like an air conditioner you would have to turn the power off at the main panel and then physically remove the wires connecting the Air Conditioner to the disconnect. Then turn the power back on and see if the disconnect still trips. Again if it does you have a bad breaker or a short somewhere in the box. If it doesn't trip you have a bad motor whose windings are likely shorted or some other condition that is drawing more than 40 Amps.
How do you know when a single pole switch is bad?
The first clue would be,having voltage at the terminal of the switch, when the switch is turned on,the circuit does not energize.
Can a bad fuse cause a single window from rolling back up?
No. If it goes down but not up, it most likely is a bad switch.
Why does a new AC in a new house throw the outside circuit breaker once a week?
If the breaker only trips once a week you may have a bad breaker or the breaker may not be large enough for your A/C unit. You should also have an electrician look for any loose connections from the unit to the breaker panel. (It is not uncommon to have a bad breaker)
