Reset the circuit breaker for a few minutes before unplugging and plugging items to determine what might have overloaded the circuit or caused the trip. Often, however, an overloaded circuit occurs simply because too many things are plugged into the circuit.
If a circuit trips because it has been overloaded, you can try disconnecting something from the circuit, and using another circuit for the electrical power instead. To help determine what caused the problem, unplug all the items on the circuit before resetting the breaker.
After it has reset and rested for a few minutes, turn on or plug in items, one at a time, to determine what may have caused the overload. If circuit overloads continue to happen in your home on a regular basis, you may need to install a new dedicated circuit and outlet for the area to handle the amperage load. To prevent circuit overloads, put large appliances and home systems like your HVAC on their own, dedicated circuits.
A short circuit happens when a hot, or active, electrical wire and a neutral wire touch, causing a large amount of current to flow and overload the circuit. A short circuit should always cause a breaker to trip or a fuse to blow and may also cause sparks, popping sounds and possibly some smoke. It may also be caused by issues like loose connections, a slipped wire or even from damage caused by animals chewing on wires.
A short circuit can be caused by a faulty electrical switch, receptacle, fixture, appliance, plug or cord. You can try to trace the short circuit, yourself or call a qualified electrician for help. A ground fault can happen when a hot or active wire makes contact with the ground wire, a grounded portion of the junction box or a grounded area of an appliance Hot wires are usually black, neutral wires are usually white, and ground wires are usually green.
When contact is made between a hot and ground wire large amounts of current go through the circuit breaker which can cause it to trip.
Ground faults usually happen when equipment is damaged or defective and can pose danger since live electrical parts may no longer be adequately protected from unintended contact. Keep in mind that circuit breakers and fuses are actually safety devices for our protection when electrical malfunctions occur.
Although, it may be frustrating when a circuit breaker trips or when a fuse blows, this action has actually served to protect us and our property. Never repair electrical cords or equipment unless qualified and authorized. Have a qualified electrician inspect electrical equipment that has gotten wet before energizing it. If working in damp locations, inspect electric cords and equipment to ensure that they are in good condition and free of defects, and use a ground fault circuit interrupter GFCI.
The danger of a short circuit is in the potential for high levels of electricity to heat up the wiring or components of a fixture or appliance and cause a fire. In areas like kitchens and bathrooms, or outdoors areas, where the floor is likely to be damp, the danger is much more pronounced. So, if you think you might have a ground fault, you should get it repaired immediately to prevent injury to you or your family. This is no job for the casual home handyman, either. If you have a home warranty with systems coverage, you can submit a request for service.
Sure, you can just reset the circuit breaker each time it trips, or you can figure out the cause of the problem so you can fix it once and for all! If the power has gone off in a certain area of your home rather than a whole-house power loss, the problem may be a tripped circuit breaker. Electrical circuits of your home are protected by either circuit breakers or fuses. All homeowners should know the location of their electrical panel or fuse box, and the opening should be easily accessible and not blocked by shelving, storage, or furniture.
This will save you time and effort if a circuit or fuse trips again. If there are two breakers or fuses for one area, such as the kitchen, take care to detail which part of the kitchen each of the two switches controls. If a circuit breaker trips because it has exceeded its maximum amperage, the switch handle will have moved between the on and off position and may show a red area alerting you that it has tripped. To reset a tripped circuit breaker, turn off the breaker by moving the switch or handle to the off position, and then turn it back on.
Rest the circuit breaker for a few minutes before unplugging and plugging items to determine what might have overloaded the circuit or caused the trip. If a circuit trips because it has been overloaded, you can try disconnecting something from the circuit and using another circuit for the electrical power instead. To help determine what caused the problem, unplug all the items on the circuit before resetting the breaker.

A short circuit happens when a hot or active electrical wire and a neutral wire touch, causing a large amount of current to flow and overload the circuit. In the case of circuit breakers, the immediate answer is to find the breaker that has tripped and reset the lever to the ON position.
When a fuse blows , a metal filament inside the fuse has burned through, meaning that you'll need to replace the fuse with a new one. But in order to avoid having it happen again, it is also important that you understand why the breaker has tripped or the fuse has blown.
In rare cases, the breaker may be damaged and will need to be replaced by a professional. But in most cases, the breaker or fuse is just doing its job when it pops. Circuit breakers are designed to trip and fuses are designed to blow and turn off the power when any of four dangerous situations occur.
An overloaded electrical circuit is the most common reason for a circuit breaker tripping. It occurs when a circuit is attempting to draw a greater electrical load than it is intended to carry. When too many appliances or light fixtures are operating at the same time, the internal sensing mechanism in the circuit breaker heats up, and the breaker "trips," usually by means of a spring-loaded component within the breaker.
This breaks the continuous pathway of the breaker and renders the circuit inactive. The circuit remains dead until the breaker lever is reset to the ON position, which also re-arms the internal spring mechanism. The circuit breaker or fuse is sized to match the load-carrying capacity of the wires in that circuit.
Hence, the breaker or fuse is intended to trip or blow before the circuit wires can heat to a dangerous level. When a circuit breaker regularly trips or a fuse repeatedly blows, it is a sign that you are making excessive demands on the circuit and need to move some appliances and devices to other circuits.
Or, it may indicate that your house has too few circuits and is in need of a service upgrade. Usually when a circuit is overloaded, the breaker takes seconds to trip due to a time delay feature internal to the breaker. A short circuit is a more serious reason for a breaker tripping. A "hard short" is caused when the hot wire black touches a neutral wire white , the bare Ground or Bond wire, or the case of a metal box.
In terms of the physics involved, a short circuit allows for a sudden unimpeded flow of electricity due to lowered resistance, and this sudden increase in current flow within the breaker causes the tripping mechanism to activate.
But sometimes a short circuit occurs not because of the circuit wiring at all, but because of a wiring problem in an appliance or device plugged into an outlet along the circuit.
Short circuits, therefore, can be a bit difficult to diagnose and fix and may call for the help of a professional electrician. The presence of a short circuit can be indicated when a circuit breaker trips again instantly after you reset it. A particular type of short circuit, a " ground-fault ," occurs if a hot wire comes in contact with a ground wire or a metal wall box or touches metal framing members.
