More information is needed as to what device you are connecting to what power supply. The only two identifiable wires are the white and green. In North America the white colour is used for the circuit's neutral and the green is used for grounding of devices.
You will have to check to make sure. Normally, with 4 wires, the black and red are both power for 220. White for neutral and bare for ground. If you are only using one leg of it, you would use the black, white, bare ones and cap the red one. Someone may have used the 4 strand because they had it or 220 was planned but not done or both the red and black are hot. You should be able to tell in the panel. Do the red and black both connect to separate breakers or to one or is the red not connected?
4 wire household wiring is black, red, (hot wires) white (neutral) and bare or green (ground wire). You say 3 wires. Is it 120v or 240v. If its 240v which is more common just use the two hots and the ground and cap off the neutral wire.
To hook up a GFCI receptacle with three wires, you would typically connect the black wire to the "hot" terminal, the white wire to the "neutral" terminal, and the bare/green wire to the "ground" terminal on the GFCI receptacle. Make sure to follow the manufacturer's instructions and turn off power to the circuit before starting any electrical work.
Sort of confusing are you using 14-3 just for the receptacle with 14-2 to the breaker or the other way around. Either way doesn't matter since you only need 2 wires and a ground for the outlets. The 14-3 should have Red, Black, White and bare wires. 14-2 should have Black, White and bare. All you need are Black, White and Bare. Forget about the red one. Hook the two outlets together with short jumper wires about 6 inches long. Looking at the outlet with the ground facing down, the bare wire goes on the bottom green terminal. The white wire goes on the left side of the outlet. The black goes on the right side of the outlet. Take the 6 inch jumper wire and go from the left side of one outlet to the left side of the second outlet. White to white, black to black, bare to bare. Connect the wires coming from the breaker to the other terminals on one of the outlets. Power comes in to one outlet and then to the second. If the wires are capped in the breaker box, you only need to connect the Black White and bare ones. Do this with the power off.
To hook up an overhead light in the kitchen to a two-way switch, you will need to run a 3-wire cable between the light fixture and the two switches. Connect the black wire of the cable to the light fixture, the white wire to the neutral wires, and the red wire to the two switches. At the switches, connect the red wire to the common terminals and the black and white wires to the traveler terminals.
The black and white cables, or possibly black and red, are analog audio. Green is one of the three component video wires, bundled together as red green and blue. Without knowing what components you have we have no idea where you should connect these, or if it is even possible with the gear you have.
Black wire to gold screw, white wire to silver screw, ground to green screw. If you are using a GFIC outlet then the hot wires coming in hook to the Line side of the GFIC receptacle and the wires going out to other receptacles hook to the load side.
The forth wire is to ground the body of the dryer. The cord should have red, black, white, and green wires. Red and black are hot, the white is neutral, and green is ground. The red, white, black in that order or reversed, black white, red, should go in a row where they connect to the dryer with the green one probably above it. If the center neutral lug has a bond to the chassis remove it. You have a dedicated wire to replace it now.
To hook up a light fixture, first turn off the power at the circuit breaker. Remove the old fixture and disconnect the wires. Connect the new fixture's wires to the corresponding wires in the electrical box, usually black to black, white to white, and green or copper to the ground wire. Secure the fixture in place and turn the power back on to test the light. If you're unsure, consult a professional electrician for help.
The GREEN and BLACK is a non stereo hook-up cable. Use the Green for VIDEO and the Black for the LEFT channel of AUDIO.
Easy as one,two and three. There are four primary wires coming from you service panel.(provided you have three phase service) you can check by looking at the weather head on the roof. if it has three wires you have single phase but if it has four then you have three phase. the hot wires will be black,red and brown. the neutral will be white or green. the welder should have a manual that will give you the lead phase wire(most likely black to black) the other two hot wires can hook to any other hot wire. The neutral goes to the white or green and posts to the panel. If the welder has a switching power supply then you must have a three phase converter.
You may not have a ground wire in your older housewiring. Hook it somewhere to the metal plate that holds the fan to the box.
I have a 1966 mustang 6 cylinder i put a auto matic trans in a later year not sure of year. I need to hook up the back up lights their are two black/red wires coming out of the floor board and four wires out the side of the transmission the colors are orange?/lwhite orange/white white/or yellow and black/white which one or lmore than one do i hook to the black and red wires coming out of the floor board. thanks tab ashford
well, Sandy hook elementary school colors are green & white
To hook up a GFCI outlet correctly, first turn off the power to the circuit. Remove the old outlet and connect the wires to the corresponding terminals on the GFCI outlet - black to brass, white to silver, and green/bare to green. Make sure the wires are securely connected and then install the GFCI outlet into the electrical box. Turn the power back on and test the outlet to ensure it is working properly.
each needs a separate 20 amp feed
