Helpful Tips

01.What does GFCI mean?

GFCI stands for Ground Fault Circuit Interrupter, it's an electrical device that protects by detecting potentially hazardous ground faults and quickly disconnecting power from the circuit. GFCI's should be installed in the kitchen, bathroom, garage and outside outlets.

02.What should I do if a receptacle or light switch does not seem to be working?

IF your outlet does not seem to work, insure that it's not on a switch. If the receptacle is not on a switch reset the GFCI or circuit breaker at the main panel. If a light is plugged into the outlet check to insure the bulb has not burned out. If none of these solve your issue then we recommend calling a licensed electrician to evaluate your situation.

03.What are the Red and Black buttons on the front of my GFCI outlet?

The black button is a test button, when pressed it deactivates the outlet and any outlets fed from it. This indicates the GFCI is working properly. The red button is the Reset - when depressed it reactivates the outlet in the event of deactivation resulting from a fault.

04.How do I reset my breaker when it has tripped off?

First, disconnect or shut off any additional devices that may have caused the breaker to overload and trip. Breakers are mechanical devices and must be turned all the way off before turning back on. Turn the breaker back on. If this fails to reset the breaker, there may be a more serious problem, Call Harrelson Electrical (800) 732-0585 or visit our Contact Harrelson Electrical page right away to schedule an appointment.

05.I want to install a ceiling fan where there is currently a light fixture, can I do this?

Yes, in most cases but there are several things you should consider first. It is imperative that the fixture box is properly rated and supported for a ceiling fan. Also is the wiring that is currently run to the fixture box correct for the ceiling fan? Will you need to have an additional switch installed so that you can control the lights independently of the ceiling fan? Harrelson Electrical can help you with this installation and make sure that everything is rated correctly. .

06.How do I know when an electrical outlet has become unsafe or should be replaced?

There are several indications that an electrical outlet has become unsafe or should be replaced. First if an electrical plug can no longer hold tightly in the outlet, second if part of the outlet is broken or chipped and finally if it's warm to the touch.

07.One of my circuit breakers keeps tripping; can I have the next highest circuit installed?

No, The breaker size/rating is determined by the size of the wiring. If there is an overload and the breaker does not trip because it is oversized/overrated, then the wiring on that circuit can easily start a fire in your home.

08.Why is there no power to a circuit and/or multiple lights are dead in my house?

Check the circuit breaker to see if it is tripped. To properly reset any breaker, first turn it off (this will be a stiff click). Then turn it back on. Sometimes when a breaker trips, it does not necessarily move the breaker switch to the off position. It must be switched off and back on to reset the tripped breaker.
