Circuit Breaker Tripping Off?
A circuit breaker is designed to trip off when it detects too much power running through the wire it's protecting. There are three main reasons circuit breakers trip off:
1. There is a short circuit.
2. There is an overloaded circuit.
3. The circuit breaker is broken.
Short Circuits
Short circuits occur when two electrical wires accidentally touch each other. A short circuit will immediately cause one of your circuit breakers to trip off or one of your fuses to blow.
To fix a short circuit, ask yourself this question: "What was happening right before the short circuit?" If you had just plugged something into a receptacle (outlet) or turned on a light or an appliance, then this gives you a clue as to what caused the short.
If you just plugged in an iron, for instance, you can simply unplug the iron and then re-set the circuit breaker or replace the fuse. If everything is now OK, then your electrical system is fine - and it's time to get a new iron!
If, however, you can't find anything plugged in which is causing the problem, then it's time to call a good electrician to locate and repair your short circuit.
Overloaded Circuit
Overloaded circuits occur when too much power is running through an electrical wire. To protect the wire, the circuit breaker does its job by detecting the overload and tripping off. The solution to this problem is to remove some of the appliances that are connected to the overloaded wires. You may wish to add a new set of wires so that you can supply power to all your appliances. For this, you'll need a good electrician.
Broken Circuit Breaker
Sometimes circuit breakers just wear out and need to be replaced. A knowledgeable homeowner with electrical skills can do the job. Otherwise, hire a good electrician.
Resetting Circuit Breakers
The first thing to understand is that a circuit breaker can have tripped off even when it looks like it's in the "ON" position. This is because a circuit breaker will sometimes trip off internally, without the "ON/OFF" handle flipping to the "OFF" position.
This is what to do when you have a loss of power that you suspect may be caused by a tripped circuit breaker.
1. Shut down any computer equipment that may be affected by a loss of power.
2. Go to your circuit breaker panel and firmly flip the first breaker OFF and then back ON again.
3. Do the same thing with each circuit breaker until you have flipped all of the circuit breakers OFF and then back ON again.
4. Now check and see whether the power is back on.
5. If your power has been restored... you're done! If your power is still out, it's time to call an electrician.
Note: About 40% of all electrical power problems can be solved using the above technique. Good Luck!
What is a GFCI?
Answer: A GFCI or Ground Fault Circuit Interrupter is a special breaker or receptacle providing extraordinary protection from shock. The GFCI can tell if current as low as 5 milliamps is “leaking” out of a circuit to ground. If the GFCI senses this leakage it will de-energize the circuit. If this current is “leaking” through your body to ground because you have touched an energized piece of equipment you may feel a shock but it will be a very short duration before the circuit is turned off by the GFCI. These are the receptacles with the “test” and “reset” buttons found in many bathrooms and kitchens.
