Electrical FAQs

Q: Why do the lights dim when I turn my TV, amplifier, or computer on?

A: The reason lights may dim when certain appliances are turned on is because the wire in that circuit now has to share its area with more current. The "in rush" current that is generated by turning something on can sometimes overwhelm a circuit, causing the lights to dim. The National Electrical Code requires a minimum of 14 gauge wiring for general purpose circuits. This wire is too small to handle in rush current. Therefore, Triniti Electric uses 12 gauge wiring when necessary, eliminating this problem.

Q: What is the difference between GFCI (ground fault circuit interrupter) and AFC (arc fault circuit interrupter)?

A: GFCI receptacles and breakers turn themselves off in the event of a ground fault. Meaning that if a path to ground exists other than the designed grounding system,(i.e. a person submerged in water, or holding a copper pipe) the circuit will turn off. An AFCI receptacle or breaker turns itself off in the event of an arc. Like if a person were to drive a nail into a wall damaging the wire inside of that wall. This type of protection prevents fires and is required by code in certain applications.

Q: What if all the plugs in my house have only two slots instead of three?

A: Before revisions of the code, a separate ground was not required in most applications. Now, a separate ground is required by code. (the third slot in plugs) It is also much safer to have this type of plug. The plugs that have two slots can be changed out with new plugs with three holes, but a ground will not be present. The correct fix for this is to bring a seperate ground wire to the plug and change the plug out to a new style plug.

Q: Should I attempt to work on simple electrical changes in my house or office myself?

A: Absolutely not! Except if you are sure of how to do it safely, and within current code regulations. If you are not confident with these things, you should call someone who is. Electricity is a complex beast who is easily controlled, but only if you know what you're doing. It is better that you don't take a chance!
