There may be a few glitches in the electric system in your home that have occurred so frequently you do not even notice them any more. You may figure the problem is normal and have learned to work around it. However, the electricity In your home should work consistently, with no glitches, to be safe. Don't overlook the following issues that need an electrician to repair.
Tripping Circuit Breakers
Having a circuit breaker trip when you plug in a few extension cords or power strips is a warning that you are overloading the system. Once you reduce the load on the system, it will stop the problem. However, if the circuit is switching off when you have nothing extra plugged into it, you need to contact someone to check it out. When the wiring was installed in your home, the outlets and what they could hold were all figured out so that the correct breaker could be used. If normal use is causing the breaker to trip, there are probably problems with the wiring.
Flickering or Dimming Lights
Flickering and/or dimming lights could be caused by loose light bulbs. However, if you have tightened all the bulbs and they are still flickering, it is best to call in a professional. The problem could be other, large appliances on the same circuit, a problem with the fixture itself, or something wrong with the wiring. If there is too much on the circuit the electrician can install another one to take up the slack. If it is the fixture, it can be replaced. If it is the wiring, the electrician will fix or replace that.
Outlets that Do Not Work
You may not worry about a single outlet that doesn't work and just plug everything into a different one. However, a nonworking outlet usually only occurs when there is something wrong with the wiring. It could be that pests got into the walls and chewed through the wires. This is a fire hazard and needs to be fixed as soon as possible.
While you may not worry if the lights flicker a bit when you turn on the dryer or care that the outlet behind your dresser doesn't work, it is important that you find out why these glitches are occurring. Letting any type of electric problem go unchecked could cause voltage surges that destroy anything plugged into the same circuit, or even worse, a fire. Contact a professional electrician for electrical repair as soon as possible.
