In normal home wiring the black and white supply the circuit voltage. The green conductor connects to the green screw. The black conductor connects to the brass coloured screw and the white conductor connects to the silver coloured screw. There are additional terminals on the receptacle that connect to the down stream side of the circuit. By making these connections on the GFI receptacle all downstream normal duplex receptacles are also protected.

How do you wire a ground fault switch?
To replace the wire ground fault switch, you need to switch off electric power from the source. After switching it off you can use the screwdriver to open screw and remove the faulty switch and replace it with a good one. <<>> There is no such a device as a ground fault switch. There is a ground fault breaker and a ground fault receptacle.
What are the common wiring in a receptacle?
Black wire is HOT, white wire is NEUTRAL and bare or green wire is GROUND. The black wire goes to brass colored screw, the white wire goes to silver colored screw and the bare wire goes to green screw that is connected to the metal "frame" of the receptacle.
Should a 3 wire 250 volt drier be grounded?
Yes, most definitely. Provisions for the ground wire in the dryer receptacle should be used. The feeder cable's ground wire is first grounded to the receptacle's junction box ground screw and then taken to the receptacle's ground terminal. The dryer plug configuration will match up to the dryers four wire plug in cable. When the plug is connected into the dryer receptacle the ground terminals of both devices will match and the ground wire will be continuous from the voltage source at the distribution panel and complete the circuit at the dryer. This low impedance electrical path will conduct any ground fault that could occur at the dryer and trip the feeder breaker of the dryer circuit, there by removing the fault current from the dryer circuit.
How do you extend the electric outlet at the basement?
Parallel connect the new receptacle to a receptacle in the existing circuit. Black (hot) existing to black (new), white existing to white (new), ground existing to ground (new). Make the ground wire coming into the new receptacle box longer so that it can be looped around the ground screw located in the receptacle box first and then connect to the receptacle without having a break in the wire.
How do you install a 12v power receptacle on your motorcycle?
Run a fused power line from the receptacle to either the battery for constant Hot or to the fuse box for an ignition controlled receptacle and ground the receptacle either by mounting on a metal surface or run a ground wire from the body of the receptacle to a good chasis ground
How do you connect a ground wire for a light fixture?
The very first thing you do is shut off the breaker to this circuit. Now if you mean in a receptacle or switch box, the incoming cable ground wire, first connects to the box ground screw and then it is twisted with the outgoing ground wire and a wire nut is screwed on the ends of the wire to hold the wires together. In the case of a receptacle the same procedure is applied except there is a short piece of ground wire also twisted to the incoming and outgoing wires. This is called a pigtail and it goes to the green ground screw on the duplex receptacle
How do you wire a 3 wire European oven white black green to a US receptacle with 4 wires white black red and bare?
Connect the white wire from the European oven to the white wire in the US receptacle. Connect the black wire from the European oven to the black wire in the US receptacle. Connect the green wire from the European oven to the bare wire in the US receptacle. The green wire serves as the ground wire since you don't have a separate ground wire in the US receptacle.
What is a silver screw in a new wall receptacle for?
The screw is actually only silver in color and it is where the neutral wire(s) get connected to, (white wire). the gold colored screw gets connected to the positive(black or red) wire(s). Green screw is for ground wire.
What do you do with the green wire from a light if the receptacle doesn't have one?
Green typically represents a ground so you would connect to the bare wire at receptacle or look for a green headed screw.
What is the the purpose of the ground wire on an appliance?
If there happens to be a fault on that appliance the ground wire is the faults path back to ground.
Your electric stove has a 3 prong plug your new stove has a 4 prong stove you bought a new 4 prong outlet but on your old outlet it oly has 3 wires no ground wire how do you ground it?
Look in the back of the range receptacle box that is in the wall. The three wires coming in should have a bare ground wire in the cable set. It wasn't brought to the receptacle because there was no place for it on the three wire receptacle If you find it back there under a screw terminal just add another short piece of wire under the screw and then connect the other end of the short wire to the new ground terminal on the new four position receptacle The wire should be equal in size to the size of the wire that exists around the ground terminal now. If the house is so old that the range cable did not have a ground wire in it the code allows a separate green ground #10 wire to be taken from the breaker panel box to the existing range receptacle This wire is to be bonded on each end. At the panel end to the ground buss and at the receptacle end around the ground screw at the back of the box unbroken and then to the new four position receptacle ground lug.
Will a ground fault interrupter work at any outlet with only 2 wires?
Yes. GFCI receptacles do not rely on a ground conductor to work. They sense any difference between current flowing in the hot wire and current returning in the neutral wire. Under normal circumstances, these two currents will be exactly the same. If there is a difference, then some of the current is flowing from the hot to somewhere else, possibly through a person to ground. This causes the GFCI to trip. The National Electric code even permits an old 2-wire receptacle with no ground wire to be replaced with a GFCI 3-prong receptacle. No ground wire is used, and the GFCI must be labeled "No Equipment Ground". See NEC Article 406.3(D)(3)(b) and (c). This is the only legal way to install a 3-prong receptacle in place of a 2-prong without running a new ground wire.
