Do you need a gfci outlet if you have a gfci breaker?

Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.


How do you wire an outdoor timer into a GFCI outlet?

I assume you are hard wiring it and not plugging it in. The power coming into the GFCI outlet connects to the line side of the GFCI outlet. If you want the outdoor timer protected by the GFCI then connect the wire going to the timer to the load side of the outlet. If you do not want the timer protected then connect it to the line side. On the back of the GFCI if you look closely you will see Line & Load marked on the back.


If I have 20 amp GFCI receptacle and would like to add another receptacle to the GFCI Does the new plug also need to be 20 amps?

Yes.


Can you use a GFCI plug into a GFCI outlet?

Yes you can. Lots of blow dryers have GFCI protection built in.


What happens when you plug a GFCI protected extension cord into an outlet that is GFCI protected?

In a word NO, that will not cause either GFCI to trip. The correct term is GFCI (Ground Fault Circuit Interrupter)


When there is a lot of rain the outside GFCI trips even though it is covered?

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


How do you install multiple GFCI receptacles?

A GFCI receptacle can extend its protection to regular receptacles connected to the output side of the GFCI. Each actual GFCI receptacle should be directly connected to a breaker in electric panel.


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.


Can a circuit with a GFCI be shared at the box?

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.


What is the trip time for a GFCI?

The trip time for a GFCI is from 15 to 30 milliseconds.


How many amps does gfci trip at?

GFCI receptacle are designed to trip on 5 milliamps.


If the test switch is bad on a gfci will the breaker still work?

If the test switch is faulty then there is no convenient way to determine if the GFCI is functioning, and technically, if the test switch is faulty, then as it is a part of the GFCI, the GFCI is faulty and should be replaced.
