GFCI (Ground Fault Circuit Interruptor)

InstallingA GFCI device is installed in the following manner: The hot and neutral from the power source (coming from the breaker) are connected to the "LINE" terminals (hot to brass screw and neutral to silver screw).

The hot and neutral of any receptacles that are to be protected by this GFCI (if any) are connected to the "LOAD" terminals.

The ground (if present) is connected to the GREEN grounding screw of the device.

If no ground is present, the device shall be marked "NO EQUIPMENT GROUND", and no grounding wire shall be connected to any receptacles protected downstream.

Professional OpinionGFCI receptacles may be installed on circuits protected by a GFCI breaker, but the devices may interfere with each other and cause nuisance tripping. I would advise against this. I would also advise against protecting anything from the LOAD terminals, and would instead install a separate GFCI at each receptacle location. This makes finding a tripped GFCI simple.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized

GFCI (Ground Fault Circuit Interruptor)

A GFCI receptacle is designed to prevent electrical shock. This device constantly monitors the current flow in the hot and neutral conductors.

The current in the hot and neutral conductors should match. If the current flow doesn't match, the device disconnects itself and any receptacles it protects from the electrical source.

Because the device does not actually check the ground current, it can be installed without a ground wire. A GFCI wired in this manner, or any receptacles protected by it, is required to be marked "NO EQUIPMENT GROUND" and is an allowable method of changing two-wire ungrounded receptacles to three-wire grounding receptacles.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work AND

always use an electricians test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

A GFCI outlet is designed to protect the homeowner from electrocution near water. You must have a GFCI installed at any outlet that is within 6' of a water source. You connect the incoming power supply to the LINE side of the outlet and all the other regular outlets you wish to protect to the LOAD side of the outlet. This way you do not have to install a GFCI at all the outlets on that circuit. That one GFCI will protect multiple outlets on the same circuit.

a gfi works like a breaker box in an outlet. often used in bathrooms and kitchens. it gives you the option to cut off power to outlet.

Are there 220 volt gfci circuit breakers?

Yes, Electrical supply stores usually carry them


How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?

While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.


Can you use a 220 breaker in place of 110 breaker on 110 service?

Answer for USA, Canada and countries running a 60 Hz supply service.Breakers are rated in amperage and by the amount of poles that they have. Your classification of a 220 breaker is described in electrical terminology as a two pole breaker.Choosing the amperage of the two pole breaker depends upon the 220 volt load that it feeds.Two pole breakers for 220 volt loads.Single pole breakers for 120 volt loads.If the service is only 120 volt then every other bus bar in the panel will be energized. If the panel is a 120/240, then every bus bar in the panel will be energized.This is how and why a 240 volt load requires a two pole breaker.To the answer, yes you an use a two pole breaker in a 120 volt service but only one side of the breaker will have voltage on it depending on where it is situated in the panel board.


Are electric cook tops 110 volt or 220 volt?

Mine was 220 and I suppose they all are.


Will a 220 volt 50 Hertz refrigerator work on 220 volt 60 Hertz?

No because the pump motor will run too fast and the lifetime of the fridge will be severely reduced.

How do you test a 220 volt breaker?

You will need a multimeter to check a 220 volt breaker. You should unplug appliances that go to that particular breaker. Use the multimeter at the breaker to check the voltage. If it shows 220, then the breaker is okay. If it doesn't, then the breaker is no good.

How do you hook up a water heater with red black and white wires?

Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
