GFCI protection (ground fault circuit interrupter) is required for many receptacles or receptacles throughout the home and in outdoor locations.
This protection can be provided by a GFCI circuit breaker/breaker or by GFCI receptacles/receptacles. Advantages and disadvantages, depending on the installation.
Protection of entire branch circuits of individual receptacles / receptacles.
GFCI breakers/breakers are simple:
install one in the service panel (circuit breaker box) and add GFCI protection to the entire branch circuit, including wiring and all devices connected to the circuit. In cases where AFCI protection is also required (increasingly common), there are dual function GFCI / AFCI circuit breakers that can be used.
GFCI receptacles / receptacles
Single location protection offers GFCI protection only in one receptacle, while multi-location wiring protects the first GFCI receptacle and all receptacles downstream (including standard receptacles) in the same circuit. However, it does not protect the part of the circuit that lies between it and the main service panel, that is, the branch cable before the GFCI.
GFCI receptacles/receptacles must be accessible
When a GFCI breaker / Breaker trips, you must go to the service panel to reset it.
Generally, resetting a receptacle is more convenient than going to the service panel to reset a breaker/breaker, but remember that if you connect a circuit to protect multiple locations from a single GFCI receptacle, that receptacle controls the entire flow to down. Any wiring problem below can cause the receptacle or receptacle to the trip, and you will have to find the main GFCI receptacle to reset the entire protected part of the circuit.
Efficiency in the installation.
For example, if you need GFCI protection for only one or two receptacles, for example, for a bathroom or laundry room, it probably makes more sense to simply install the GFCI receptacles or receptacles in those places. Also, if you are a DIY expert and not familiar with working in a service panel, adding a receptacle is a simpler and safer job than replacing a circuit breaker will be easy for you.
In other situations, the circuit breakers or protections on the GFCI type board have more practicality.
GFCI receptacles have bodies much larger than standard receptacles, so in some cases, the physical space inside the wall box can affect your choice. With standard-sized boxes, there may not be enough room to add a GFCI receptacle securely, which makes a GFCI breaker or breaker the best choice. The cost can also be a factor in the decision.
