Why does my circuit breaker keep tripping?
One of the main reasons your home’s circuit breakers keep tripping is circuit overloading. This happens when you connect more devices throughout your household than the circuits can actually handle. These excessive electrical flows cause the system to overheat and shut down automatically.
Why does my breaker tripped?
A tripped circuit breaker can be the result of loose wiring. Common issues like the flickering of the lights are caused by faulty wiring. A homeowner should check for any loose wires, replacing them with the help of a professional if need be. You should also check each area of your home for any possible issues. This includes checking all appliances that are connected to the circuit.
Why does my ground surge happen?
Ground surges happen when an active electrical wire makes contact with a ground wire. These faults create excess current, overheating and causing a circuit breaker to shut down to prevent further damage or electrical fires automatically. Handling a ground surge is dangerous and requires the help of a licensed electrician to help determine the culprit of these issues.
What is a short circuit?
Short circuits are a huge fire hazard and should be taken into account immediately. Short circuits happen when an active electrical wire contacts a neutral wire. This is usually the result of undetected faults within a home’s wiring network. Short-circuiting produces massive amounts of heat, causing the circuit breaker to trip. This can even result in odd noises, sparks, and a burning smell.

However, the chances of circuit breaker failure can be minimized by equipping the electrical panel with a surge suppressor. While you can the minimize the chances of the above-failure with a surge suppressor, ...
Why do circuit breaker circuits shut off?
Branch circuit breakers are designed to shut off power to individual circuits if they overload by trying to draw more power than the wires can safely handle, and the main circuit breaker is much the same. The main breaker shuts off power to the entire house if the overall load demand grows too high or if there is another serious problem in the electrical system. Usually, these problems involve momentary power surges, but sometimes there may be system problems that will need to be diagnosed. It is fairly rare for the main circuit breaker to "trip," because usually, it is individual circuit breakers that trip long before there is a need for the main breaker to shut off.
What to do if a circuit breaker fails?
If an individual circuit breaker fails and loses its ability to trip as designed, it may actually be the main breaker that trips to provide the secondary safety shutoff. Again, there is a recommended procedure for resetting the main breaker: First, turn off all the individual circuit breakers controlling branch circuits.
How to turn on a circuit after resetting a breaker?
It's much safer to turn on individual circuits one at a time after resetting the main breaker. Reset the lever on the main breaker to the ON position.

How do circuit breakers receive power?
The individual circuit breakers for branch circuits will receive their power by connecting to one or both of these hot buss bars. Circuits for 120-volt circuits connect to one buss bar; circuits for 240-volt circuits connect to both hot buss bars.
What is the difference between a main circuit breaker and a breaker?
The Difference Between Breakers. The main circuit breaker is really no different than any other breaker, but it is designed to handle the large amperage load of the main feeder wires bringing electrical power to the house. For this reason, it will be by far the largest breaker in the box in terms of amperage rating.
What to do when resetting a breaker?
By doing this, you will protect yourself from any possible electrical flash or sparks. The chances of this happening are remote, but such episodes have been known to occur.
