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.
Can a new breaker be bad?
Certainly. No manufacturing process is perfect.
My circuit breaker keeps popping I have replace the 2-prong outlet with a 4-outlets and why is it still popping?
A breaker trips when there is too much current. If you unplug everything on the circuit and the breaker still trips then you have a wiring problem or a bad breaker. From your description it is not possible to be certain if the problem started when you installed new outlet or previously. You have to describe your problem in better detail to get a good answer. When you have a circuit that trips the corresponding breaker, you need to go through each outlet on the circuit and rule it out as the problem. This can be done by pulling each outlet, from the wall and systematically remove wires from outlets while power is off and determining when problem goes away.
Why does the heater on your AC will only turn off when you switch the breaker off and will only turn on when you turn the breaker on?
a bad thermostat or miswire of the low voltage wiring or a bad heating relay stuck in the heating mode.
What is tripping relay?
You need to remove everything connected to the breaker and see if it still trips. If it does it is in the wiring or possibly a bad breaker. Disconnect load from breaker and see if it still trips. If so replace the breaker. If it still trips and is not the breaker then you will have to start pulling each outlet from wall and checking after disconnecting each outlet.
How do you determine if a breaker switch is bad?
You replace the breaker to see if that fixes the problem. There simply is no other practical approach. There exists testing equipment that will do this but it is much too expensive for general use.
1997 Lincoln town car lights flicker you replaced light switch lights still still go out must be a relay or circuit breaker where is the circuit breaker located?
Bad ground.

Swap it with another like breaker.
How can you tell if a circuit breaker is bad?

I have a 2003 Pontiac sunfire my headlights stoped working i replaced the bulbs and still nothing what could be making them not work?
Bad switch? Bad relay/ Breaker tripped?
What could be wrong if you put an alternator on van but it's still stalling?
bad voltage regulator is a possibility
The lights on your 02 crown vic went out what could it be and how can you fix it?
Check bulbs Check fuses Bad light switch? Bad voltage regulator causing alternator to spike blowing out bulbs? Headlight circuit breaker? Headlight relay?
If no power is being delivered to a specific circuit when the breaker is on is the breaker bad?
Look very closely at the breaker, it could be in the tripped position. Compare the position of the handle in relationship with the other breaker handles. If it seems a little bit out of align move the handle to the full off position. You should hear the breaker reset if it was tripped. Move the breaker to the full on position, this should restore the circuit. If the breaker trips off instantaneously when moved to the on position, check what caused the fault and remove it from the circuit.(LIFE SAFETY WARNING! [disclaimer]Electricity is dangerous!You can be injured or killed!Improper installations can cause fire, injury and death!Troubleshooting is the height of the electrician's art...The only reason there is "not enough voltage" somewhere is because there is a partially open connection providing resistance and a location to allow a voltage drop [bad splice, bad switch, bad breaker, broken wire, burned splice, ...].It is the knowledge of how electricity works, and of the methods and materials used to create a functional wiring system, that enables a skilled troubleshooter to locate the problem and repair it.Where should the "voltage" be, and how does it get there?When you understand that, you will understand what is keeping it from getting where it should be...You can only answer this question by taking a voltage reading, using a voltage tester, from the neutral bar to the output terminal of the breaker itself!This exposes you to dangerous voltages in an open panel!TURN THE POWER OFF!Call a licensed electrician!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.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure 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.
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)
Why would my 3 prong outlet for the electric range stop supplying 220v and only has 110v now?
It's either a faulty breaker, a poor connection, or a bad outlet. Make certain that you still have 220 at the breaker panel. Then test the output of the breaker in question. Finally, if all of the above test out Okay, verify the voltage at the outlet with the outlet pulled out of the box. If you haven't done these things before, contact a qualified electrician to do this for you. Understand that electricity can be dangerous and there is a very real possibility of electrocution.
