Ground fault circuit interrupters (GFCI) are a common sight in households across the U.S. While they've been a part of new construction code requirements since the early 1970s, many homeowners are unaware of their impressive benefits. Here's a closer look at their unique qualities and why electricians recommend them for homeowners.

A Guide to GFCI Outlets

What Are They? 

The purpose of GFCI outlets is to prevent fatal electrical shocks. Such receptacles monitor the electrical current constantly. If there's an interruption in the flow or an imbalance, the GFCI trips the circuit to cut off the power to the outlet.

Impressively, the units can detect and react to a change as small as five milliamps. As such, users are able to avoid lethal electrocution, which is why they're commonly placed next to sources of water, where the risk of shock is highest.

How Are They Different?

The capabilities of GFCI outlets far exceed that of standard variations. For one, traditional outlets don't eliminate the current when grounding occurs, which puts individuals at risk for electrical shock. However, standard receptacles can be protected by installing a GFCI system at the beginning of the branch circuit.

Visually, GFCI units are also easy to pick out as they feature both a "test" and "reset" button, allowing you to routinely check their functionality.

Which Areas Benefit From Them?

GFCI receptacles are ideal in any room where moisture is regularly present, including bathrooms, kitchens, and laundry rooms. They're also useful for boosting safety in garages and exterior outlets. As a result of building code requirements, newer homes should already have GFCI outlets in these areas. Owners of older homes, on the other hand, should consider working with an electrician to upgrade their outlets for enhanced protection.
