Reasons to Install GFCI Outlets
Have you ever heard people talking about "GFCI outlets" and wondered what sort of gobbledegook is coming out of their mouths, let alone whether it's relevant to you? If so, you're not alone: many people are confused about what they are, how they work, and why they matter. We're here to straighten
Posted — UpdatedNormal electrical circuits remain operational in these situations, causing burns, shock, and death in some cases. GFCIs, however, cut off when they sense a ground fault. They are extremely sensitive and fast acting, reacting to promptly stop the flow of current as soon as they notice a disparity between the current flowing out of the hot pole and into the neutral pole.
GFCI protection can be provided in several ways. One is an actual electrical receptacle, AKA outlet. You may have seen a GFCI outlet without realizing it: it looks like a normal outlet, except that it has "test" and "reset" buttons. Depending on the model, the buttons may be colored, and the outlet may have an indicator light to show it's working.
Portable GFCI protection is also available in the form of specially equipped extension cords and modular plugs. You plug the GFCI plug into the wall, and then plug in the item you're using. Additionally, GFCI breakers can be wired directly into your breaker box.
Be aware that because of their complexity, GFCIs need to be regularly tested to make sure they are functioning. You can do this by pressing the "test" and then "reset" buttons. If the GFCI does not cut power when you hit "test," it is not working properly, and you need to contact an electrician to discuss the issue. An electrician is also needed if a GFCI is randomly cutting out, or if you notice strange noises or smells around an outlet.
