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.


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.


Is it NEC code to have a water fountain on a GFCI protection?

Yes. NEC 2005 440.21


Why and when would you use a GFCI breaker within a older home with a groun?

You need a GFCI outlet at any location that is within 6' of a water source. You also need a GFCI outlet in a room with a concrete floor, any garage, and any location outside the home or under the home in the crawl space. A GFCI outlet protects you from electrical shock near water or moisture. You can protect more than one outlet with 1 GFCI outlet. Connect the incoming power to the LINE side of the GFCI outlet and all the other outlets getting power from that outlet to the LOAD side of the GFCI outlet. That way they will all be protected by 1 GFCI. A GFCI breaker is used to protect an entire circuit and not just individual receptacles. It is often cheaper to use GFCI receptacles than a breaker, especially if "piggy-backed" such as described above. It is also more convenient to reset a GFCI receptacle than to reset a breaker. But your question is "why." From this I suspect you may be misunderstanding the difference between a breaker and GFCI protection. To keep things simple let me say that a GFCI does not work on the same principles as a standard breaker. It provides a much safer protection than a standard breaker. Even with a ground you need GFCI protection as listed above.


Can a gfci go bad?

Most definitely. GFCI receptacles have a test buton, and should be tested regularly. you can also buy inexpensive plug-in testers at most home centers and electric supply houses.

What device senses short circuits and stops electrical flow when ground fault occur?

It is a Ground Fault Circuit Interrupter or GFCI. It can either be equipped in your electric panel as a GFCI breaker, or in a GFCI outlet which also lets you extend the GFCI protection to other outlets "down the line" from the GFCI outlet.

Can you use a GFCI plug into a GFCI outlet?

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

Plugging an electric heater into a GFI outlet caused the lights and other outlets to go out but didn't trip the circuit breaker why?

A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.


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)


Where does a GFCI go?

GFCI protection is required for most outdoor receptacles, bathroom , garage wall outlets, kitchen, and all receptacles in crawl space.


Why won't the GFCI trip the panel box when shorted?

A GFCI is not an overcurrent protection device. It only protects people from electrical shock. However, if you were to create a perfect hot to neutral short the GFCI would not trip and the panel breaker would.


What does a GFCI protect you from?

An electric shock under a fault condition where you happen to be the ground conductor.

Do dishwashers require GFCI protection?

Is the outlet located near a water source, if so, yes.
