GFCI=Ground Fault Circuit Interrupter
It's an electronic circuit breaker that compares the current on two wires. If the current is NOT equal, the breaker trips and does so quickly enough to prevent electrocution in the event of a "ground fault".
A GFCI can detect ground faults on the specific circuit it is connected to. If multiple outlets are on the same circuit protected by a single GFCI outlet, the GFCI can protect all of them. However, if the outlets are on different circuits or not downstream from the GFCI, they would need their own GFCI protection.
It is recommended to have GFCI protection for all electrical outlets in a garage to help reduce the risk of electric shocks. This would typically involve installing a GFCI outlet at the beginning of the circuit to protect the rest of the outlets downstream.
No, if the test switch on a GFCI is faulty, it can prevent the breaker from working correctly. The test switch is an essential component for checking the functionality of the GFCI, so if it's bad, it could impact the overall operation of the device.
GFCI receptacles are designed to trip at around 5 milliamps (0.005 amps) of current leakage to ground. When the GFCI detects this level of imbalance, it quickly shuts off the power to prevent electric shock.
You can determine if an outlet is after a GFCI by pressing the "test" button on the GFCI outlet. If the GFCI trips and cuts off power to the outlet, then that outlet is downstream from the GFCI. If power is not cut off, then that outlet is upstream from the GFCI.
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
No, but they will have a coaxial INPUT.
Yes, it is recommended to have both GFCI outlets and a GFCI breaker installed for maximum electrical safety in your home.
Yes you can. Lots of blow dryers have GFCI protection built in.
my gfci trips when my christmas lights r on and it rains is the gfci bad or is this normal of a perfectly working gfci
Your GFCI may not be resetting due to a faulty connection, a tripped circuit, or a malfunctioning GFCI outlet. It is important to check the wiring, test the outlet, and possibly replace the GFCI if needed.
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.
The GFCI reset button may not stay in if there is a fault in the electrical circuit or if the GFCI itself is faulty. It is important to have a qualified electrician inspect and repair the GFCI to ensure safety.
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
Yes, the GFCI green light indicator is on.

The GFCI reset button may not push in if there is a fault in the electrical circuit or if the GFCI itself is damaged. It is important to troubleshoot the issue and potentially replace the GFCI if necessary to ensure electrical safety.
