What Are GFCI Devices and What Do They Do?

GFCI outlets are a critical electrical safety feature required in kitchens, bathrooms, and outdoor areas. This guide explains what GFCI devices are, how they work, and why they are essential for protecting against electrical shock.

A GFCI (Ground Fault Circuit Interrupter) is designed to protect people from electric shock. Many older homes here in Rhode Island and across New England lack proper GFCI protection. Updating these devices is one of the most effective safety improvements available.

How does a GFCI work?

A GFCI monitors electrical current in real time. If it detects an imbalance between outgoing and returning current, it shuts off power immediately (sometimes referred to as “tripping the circuit”). This prevents electricity from passing through unintended paths, including water or a person.

There are two types:

  • GFCI outlets at the point of use 
  • GFCI breakers protecting entire circuits 

Both serve the same purpose.

Where are GFCIs required to be installed?

GFCIs are required in areas where moisture increases risk, such as kitchens, bathrooms, garages, basements, and outdoor locations.

If the GFCI trips, does that mean I have an electrical problem? How do I know the GFCI is working properly?

Occasional tripping can be normal. Frequent tripping usually indicates a problem that needs evaluation.

You should test your GFCI outlets every so often to be sure they are working properly. Testing is simple. Pressing “TEST” should shut off power. Pressing “RESET” restores it. If it fails, replacement may be necessary.

If your GFCI outlets or device is not working properly, or if you don’t have them installed where they should be, get in touch with us at Atlantic Electrical Contractors. We can fix or install these critical devices to ensure you and your family are protected.
