Does a circuit breaker need to be replaced if it will not go back to the on position after it trips and is switched to off?
Not necessarily, you may have a genuine fault on the circuit that needs attention...
First thing to do is unplug and disconnect everything on that circuit and try again. If it then resets properly, one of the items you've disconnected is faulty.
With the trip reset (power on), plug in each item one by one and see if it trips again. Whatever you are plugging in when it trips is more than likely the faulty item.
The likely suspects are usually Washing Machines, Dish Washers, Kettles, cookers and Microwaves.
It could be fault, but better to be safe than sorry and check the circuit first.
If not entire sure what you are doing, get a qualified electrician to look at it.
If the trip does need replacing get a qualified electrician to do it!

yes it can because so many devices we have now don't shut off when you turn them off with the device switch. Be carful when doing this that you don't power off a refrigerator …or freezer though.
Yes a circuit breaker is a switch but it should not be used as a switch. The continuous turning off and on of a breaker weakens the internal mechanism and reduces the tripping… value of the breaker. There is in the marketplace breakers that are designed to be used as switches. These are usually used in large warehouses where the lights are turned on in the morning and shut off at night. Using these specifically designed breakers for switches does not wear out the tripping mechanism or reduce the tripping value. A circuit breaker can be used as a switch, although in most cases there are less expensive switches you can use.
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.
The tripping mechanism for most high-voltage circuit breakers is released through the use of a solenoid built into the circuit breaker. The supply to the tripping solenoid is …from a DC source located in the substation building. There are various types of protection relay that will energise the tripping circuit -e.g. an overcurrent relay will detect a fault current due to, say, a short circuit in the protected line; after a specified time delay, a pair of contacts inside the relay will close, and energise the trip solenoid, opening the circuit breaker, and disconnecting the faulted line.
A circuit breaker trips when the amount of electric current passing through it goes higher than its normal current rating. More detail The breaker trips to cut off the curre…nt flowing into in the circuit which the breaker is protecting. It is because of a fault - an electrical short in the wiring or in an appliance - that causes the circuit breaker to trip. If you - or an experienced person such as a licensed electrician - can find and fix the fault , then the breaker will not trip to cut off the current. 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. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
The operating handle will be found in mid throw. On smaller type electrical breakers there is a small trip indicator window and a red flag will be visible when the breaker has… tripped. On larger physical size breakers you will definitely see that the handle is not in the off or on position. To reset any size breaker move the handle to the full off position. You might hear a click but you will definitely feel the internal mechanism re-latch to the off position. This has reset the breaker, move the handle to the on position and normal electrical power will have been restored. If you get an instantaneous trip after a reset do not try and reset the breaker again. Find the cause of the short circuit and get it repaired. Constant and repetitive resetting will destroy the breaker and increase the temperature of the short circuit. If the short circuit is in a highly combustive area this is not good. Find the problem and get it repaired.
Why does your inside 4 outlet circuit randomly go off under no load only to come on again at random without tripping the breaker while outside lights on the same circuit stay on?
Answer When your house was wired the outlets were probably wired using the stab in terminals on the back of the outlets, these tend to cause trouble over t…ime.Turn off the power and rewire the outlets using the binding screw terminals.By chance if the outlets are wired on the binding screws, inspect all for loose joints.You may have to inspect every box and outlet on this circuit to find the problem. I once had a customer who was having a similar problem and it only showed up while playing the stereo very loud.We determined that the vibration was causing the stab in terminals to loose contact,we removed every outlet and switch and reconnected all by using the binding screws and the problem went away.Hope this helps.
A breaker can fail in several ways. It may not trip at the rated current, it may be always open, or it may be always closed. It is also possible for it to fail so that current… flows, but is restricted by internal resistance. If you can safely remove the breaker and have a volt/ohm meter you can troubleshoot basic functions of open and closed. Measure the ohms across the contacts with breaker on and off and make sure that there are 0 ohms when on and infinite ohms when off. Other than that just replace the breaker with a spare from the panel or temporarily substitute with a working breaker of the same rating in your box.
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping …under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.
A circuit breaker doesn't respond to excessive voltages, but to excessive currents (overcurrents). A miniature circuit breaker, the type you have at home, has a bimetallic s…trip and a coil, either of which will initiate a trip in response to excessive temperature (overload currents) or excessive magnetic flux density (short-circuit currents).
Answer . \nfirst 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 tot…he 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.
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.
A circuit breaker in the off position should not be pushed to the on position until the problem is what?
No. A circuit breaker is a switch, but a switch is not necessarily a circuit breaker. A "circuit breaker" is a device that will open the circuit when more current than it is d…esigned for flows through the circuit. This is an automatic function, and does not require manual manipulation (such as a person physically moving an on/off switch). Resetting is often a manual function. If taken in the context of a switch opening a circuit or making a break in the circuit then the question, Is a switch a circuit breaker, then the answer would be, yes, as the switch does break the circuit.
It probably doesn't matter. But a "disconnecting means", as the NEC calls it, is not intended to be operated while under load, which is when the equipment is running. It is in…tended to isolate the equipment so it can be serviced safely. A breaker by its very nature is intended to be operated under load. The larger the equipment, the more this matters.
It means that the person has to go and re set the breaker. If people understood that the tripping of the breaker is a safety device and by its tripping it might have just save…d them some money. By preventing a fault that a short circuit or an overload could cause might just have stopped a potential house fire.
