Electrical Services FAQ in Richmond, TX
Why does my light Flickers?
Lights flicker for a variety of different reasons. In some instances it can be normal, in others a simple thing to correct, and in a few cases indicative of a serious problem. It is important to understand why flickering might be occurring so that you can take the proper course of action to resolve the issue. Remember, a flickering light could be harmless, but it could also be the first symptom of a serious wiring issue, one which could be expensive or a fire risk. For this reason, property owners need to stay on top of this problem before it gets worse. The above are just suggestions. Remember, dealing with a faulty wiring issue, or changing a light fitting or switch, can be dangerous. If you are unsure what to do, it is always recommended to hire an electrician to assess the problem for you.
Why do I need a GFCI?
Ground-Fault-Circuit-Interrupting receptacles—the outlets with the push buttons—are designed to protect people and animals from electric shock.
They’re also known as GFIs or simply “ground-fault. GFCIs measure incoming current vs. outgoing current, and are designed to trip if the smallest fraction (around 4-8 milliamps, or thousands of an amp) are going out through some other path, whether through a person, a piece of equipment, or faulty wiring.
Why do my light bulbs burn out so quickly?
One reason bulbs can burn out quickly is if the voltage applied to them is higher than the expected voltage (120V in The USA). Wiring problems and bad transformers can cause the voltage to be out of spec. Another reason is if there is a loose connection somewhere, and the light flickers (causing unnecessary heating/cooling cycles). A third reason is if the light is in a confined space, and overheats.
In order to check the line voltage, you will need to use a voltmeter. The Kill-A-Watt is a very safe product to use to check the line voltage. Note that you should try a few different outlets, since there are generally two different phases of power (not really phases, but opposite polarities, 180 degrees apart) going into a typical house, and you need to check both of them.
