GFCI stands for 'ground fault current interruptor'. These are used near Plumbing in houses and on exterior electrical outlets and can be built into extension cords and appliances such as hair dryers. The GFCI breaks the circuit if ~20 milliamps returns through ground instead of the neutral. (A standard two-prong plug has a hot and a neutral.) If the current returns through ground, that is a ground fault and you are usually providing the path. Any current through you higher than about 30 ma is likely to cause your heart to go into ventricular fibrillation and the result is your death. The fuse or circuit breaker in the circuit is protecting the wiring, the GFCI protects you.

Need to find a gfci pool outlet?

Do you need to find the outlet at a hardware store, electrical store or around your pool area? At your pool area - GFCI's can sometimes be found around the pool equipment pad. Sometimes they are located just off the deep end of the pool at the edge of the deck straight back from the pool light if your pool has a light. However these fixtures do not have any access to an outlet. It is usually just a GFCI fixture. GFCI's can sometimes be found in shrubbery surrounding the pool. You just have to hunt for it in those locations. And there are the instances where no GFCI is provided. There may also be a GFCI in the circuit breaker box but this one will not have an outlet. What is your need for an outlet? If you have a pool light that does not have a GFCI in the system you then need to call a qualified swimming pool electrician or a qualified pool tech to install one. There are special requirements for this application.K


How do you determine if an outlet is after or before the gfci?

GFCI receptacle has the ability to protect all receptacles down stream from the device. One way to see what is on the circuit after the GFCI is to trip (test) the device. Every thing that is connected downstream will shut off and there will be no voltage present to test. Any outlets ahead or upstream of the device on the same circuit will not be effected. <<>> Trip the gici. If the outlet goes out it's after, if not, it's before.

When would it be a better idea in a residence to install a GFCI breaker instead of an GFCI outlet?

GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.
