Ground fault circuit interrupter (GFCI) outlets detect irregularities in an electrical current and automatically shut off power to the receptacle to protect people from electrical shock. A building contractor will automatically install these during new construction or home renovations because they are essential safety devices. However, if your home is older, you may not have them. The following guide outlines some more information about GFCI receptacles, including where they should be installed and why you need to update your panels to include them.

How Do GFCIs Work? 

GFCI outlets have two three-pronged plugs, as well as a “test” and “reset” button. Usually, electricity flows uniformly throughout a property. However, if a ground fault occurs, the GFCI receptacle detects this irregularity and shuts off the power to the unit. 

Electrical wires allow currents to travel from the source to the load in a continuous cycle. Most new systems include grounding rods that direct stray currents into the earth. A ground fault occurs during a surge or another issue, causing the electricity to take an unplanned path to reach the ground, such as through a person touching the outlet. Water exposure, conductive dusts, and worn insulation can trigger these dangerous situations.

For instance, if you plug in a hairdryer, the GFCI receptacle will assess the amount of power exiting the outlet. If you accidentally drop the appliance into the bathtub, the GFCI unit will detect the interrupted current and shut off the electricity to protect you from getting shocked. The receptacles work in milliseconds and can save lives. Once it’s safe to turn the outlet back on, you can push the “reset” button. They are also often tripped if the bathroom is especially steamy from a shower and moisture seeps into the plugs.

Where Should a Building Contractor Install Them? 

A building contractor will install GFCI receptacles in areas where electrical circuits, or devices plugged into them, could accidentally get wet. The receptacles are usually found in bathrooms, garages, kitchens, unfinished basements, and laundry or utility rooms. You might even want to install them in outdoor areas, such as sheds, workshops, greenhouses, and pool areas where electricity is used.

You can also ask your building contractor to upgrade old outlets to reduce the risk of injuries and fires. This also ensures the property is up to code, according to the standards set forth by the National Electrical Code.
