If a breaker isn't tripping, yet still feels quite warm, you probably are close to having too many appliances on its circuit. Breakers trip because of overloads (too many appliances), or shorts ( bare wires touching each other). These situations are quite dangerous and need to be corrected. If you can't find the problem, contact an electrician right away, and keep the circuit off.
<><><>
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.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 10y agoNo, a breaker is used to protect, the conductor that is connected to it, from over current. A conductor is rated for a specific amperage depending on its physical size. To prevent this over current, in a fault current, there has to be some protection for the conductor. This is done with either a fuse but in most cases a breaker is used.

It should never get so hot you can't touch it.

Circuit breakers are designed to operate within their correct tripping value at 50 degrees C above ambient air temperature. The size of the breakers frame has a bearing on how hot the breaker can operate. The larger the breaker the more surface area to dissipate the generated heat. The heat that is generated inside the breaker is from the contacts and the bi-metal trip. These are typically the hottest parts within the breaker. To answer the question, a circuit breaker will get hot on very hot days but as long as the breaker stays within the its parameters it will operate as it should.

What size circuit breaker is needed for a 300 watt bulb?
A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.
Where is the circuit breaker located on a 1967 Cadillac Fleetwood?
There is only one circuit breaker to my knowledge and it is for the power windows. I have a 1968 Fleetwood and it is very similar. What exactly is the problem?
Can start amps of 27 trip a 15 amp circuit breaker?
Of course! There may be a rare case where a spike of very short duration above 15 A won't trip the breaker, but in the case of a motor startup it should trip.
How does a circuit breaker operate?
A circuit breaker can be magnetic; the higher the current is the stronger the magnetic field will be, if the magnetic field gets strong enough it will pull open the circuit. A circuit breaker can also be thermal; as current travels through the circuit heat is generated (higher current = more heat), in the breaker there is two different kinds of metal bonded together, each will expand and contract at different rates, since they are bonded together they will bend and trip the circuit open. A circuit breaker can be a combination of magnetic and thermal.
What property would you be testing for if you are using a circuit breaker?
A circuit breaker is not a test instrument, it is a kind of switch that interrupts the supply when that is needed, but it is more than that because circuit breakers are specialised items, and examples exist that can interrupt currents of hundreds or thousands of amps at very high voltage.

Can a melted cup in a dishwasher blow a circuit breaker?
Its not very likely.

What is the difference of a Circuit Breaker from an Air Circuit breaker?
They are completely different. A moulded-case circuit breaker is a low- or medium-voltage device, whereas an air circuit breaker is a very large circuit breaker designed for use in high-voltage transmission/distribution substations.
If you're installing a circuit that will contain receptacles in an industrial area and the first receptacle is more than 50 feet (15.24 meters) from the load center you should?
Connect the circuit to the appropriate size circuit breaker to meet the required amperage of the circuit. Turn the breaker on and use the circuit. Unless the circuit is of a very high ampacity, plus 200 amps, don't worry about voltage drop over 50 feet.
Can start amps of 27 trip a 15 amp circuit breaker?
Of course! There may be a rare case where a spike of very short duration above 15 A won't trip the breaker, but in the case of a motor startup it should trip.
Why is it important that homes have circuit breakers?
Fuses and circuit breakers are meant to protect your home's wiring from the heat generated from fault-currents and over-currents. Over-currents happen when you exceed the amperage the fuse or breaker is rated for over a period of time (IE: drawing 20 amps on a 15 amp circuit breaker). When this occurs a fuse or circuit breaker will open the circuit so the wiring in your home will not be damaged. Over-currents happen when electricity finds a path, other than the one intended, to ground. When this happens there is very little resistance to slow the flow of electricity and the amperage through the circuit can exceed the fuse or circuit breakers rated capacity by several hundred times . These type of faults cause the fuse or circuit breaker to open the circuit very quickly.

What circuit breaker rating is commonly used for a radial circuit?
In the terms of voltage it should be in kV but when we are using the current term than it should be in kiloamperes or kA because the short circuit current level of the circuit breaker is very high.AnswerIt depends entirely on the voltage level and load currents you are talking about. It will be completely different for, say, a 132-kV system than for, say, a 230 V system. So, does your question apply to high-voltage systems or low-voltage systems?

Where is the reset button on an RCA 52 television?
If the surge protector burned up, try plugging the TV into the outlet directly. You should check your fuses or circuit breaker for the TV's outlet. Sometimes a breaker trips and doesn't flip over very far.
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.
