Which GFCI Do I Use and Where?

The purpose of ground fault circuit interrupter (GFCI) devices is to protect against electrical-related injuries. They do this by monitoring electric currents and preventing surges, shocks, and fires. GFCIs come in various forms that are compatible with several types of spaces for ultimate protection. Familiarizing yourself with common GFCI applications is the best way to get the most efficient protection for your location.

GFCI devices come in three main types: receptacles, circuit breakers, and portable systems.

GFCI receptacles appear as a regular duplex outlet. They have their own built-in breaker panel and feature a test and reset button. GFCI duplex receptacles are a common choice for wet or damp locations, and some also have additional USB ports. Their versatility and added protection make them the most common type of GFCI implementation in homes and commercial buildings.

GFCI circuit breakers offer protection across an entire electrical system from the breaker panel itself. They are best for more extensive electrical systems, or applications where individual receptacles are impractical. If you have a lot of larger appliances, GFCI breakers might be the more practical choice to avoid circuit overload.

Portable GFCI devices, available in various forms, provide on-the-go GFCI protection in areas without built-in safeguards. They are ideal for outdoor applications that use electrical power tools like mowers, drills, and other lawn tools.

GFCI circuit breakers play a crucial role in detecting ground faults within an area. They ensure the incoming and outgoing current in a circuit remains balanced through neutral wiring. If the GFCI breaker detects a ground fault, it swiftly acts by cutting off power to the circuit, and thus the whole wiring system. This prevents electrocution and fires on any of the connected appliances on the circuit.

GFCI receptacles actively protect individual outlets and allow neutral wiring for single or multiple locations. When a ground fault occurs, a GFCI receptacle will detect the imbalanced current and turn off the power to that outlet and any outlets following it in the connection. The red reset button on these receptacles simplifies the reset process after a ground fault event.

Comparatively, GFCI breakers cost more than individual GFCI receptacles. However, if you intend to buy multiple receptacles, the total cost can outweigh the expense of one breaker. It comes down to assessing your electrical needs and deciding which option is more cost-effective.

The cost of GFCI circuit breakers is usually around $40 or $50. However, individual GFCI receptacles can range anywhere from $7 to $25 per outlet. Installation costs, ranging from $50 to $200, depend on factors like expertise level and the number of outlets.

If you only need a small number of outlets, then buying the individual receptacles will be sufficient. But if your electrical system is more substantial, then purchasing one breaker might be the more efficient method. GFCI circuit breakers also provide a higher level of protection for their price.
