Red and black are the two separate 120V hot legs of a 240V 60Hz supply, green is the ground. White is the neutral. (US color coding.) === === === === === === === === Red is the 230V 50Hz hot, black is the neutral, green is the earth or ground.
Note: Those colours became obsolete for use in the UK for all new wiring installations done since 2006. The new colours are: Brown is the 230V hot, blue is the neutral, green/yellow is the earth or ground.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
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 electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.

∙ 13y agoWire colors simply allow people to easily identify routing.
Red and black are commonly used in DC circuitry.
Red wires typically signify the positive side of a circuit.
Black wires typically signify the negative side.
But they can mean whatever the engineer wants them to.
But wires are simply wires, they all act pretty much the same.
Insulation comes in different colors, composition and temperatures. That's a story for a different discussion.

∙ 10y agoGenerally the black wire would be a current carrying conductor for one phase, red a current carrying conductor for a second (split) phase and green for ground.
This would be a two-phase (residential split-phase) device (stabilizer?) with safety ground. Neutral is not needed for two phase power.

You have three colours of wire in your bathroom red black and green yellow what do they mean?
3 colors? red black green and yellow? i count 4... red is your active, or live wire. black is return, or negative wire. green is your earthing wire and yellow is more than likely a control, for a switch, possibly a heating fan or towel railing?
I see only a red and a green wire coming out from ceiling box. What are they and how do you connect them to a ceiling light?
Normally red or black is the hot wire and green is the ground. However someone may have used the green wire as the neutral wire which is normally white. Just connect the black wire from the light to the red wire and the white wire from the light to the green wire and see if it works. If not you have to pull the wires out of the ceiling box and see how they wired it.
Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
Why is there only red black and white wire ceiling and no green?
Each color means a different thing and there are green ones, they are just not as common There should be a bare wire along with the red, black and green wires in the ceiling. It is possible that it was cut off short or tied up to the box somewhere. this is the same as the green wire.
What is significance of red black and green wire in three pin plug?
I am guessing this is a 220-240 Volt plug. There is 220-240 V between Black and Red and the Green is ground.
Can green wire be used in place of black or red wire?
No. Green should always signify the ground wire.
What are the four roots of a technology tree?
red wire, blue wire, green wire and the black wire.

What wire color is ground on a 4 wire 220 volt cord The I know the green is and what red black or white?
Depending on the configuration of the cord cap, the green wire is ground, the white wire is the neutral and red and black wires are the 220 volt source.
Light switch has 4 wire colors red and white and green and black which is the hot wire?
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.

What is the car radio wiring schematic for a 2003 Kia Rio?
In a 2003 Kia Rio, the battery constant 12v+ wire is yellow/blue, the accessory switched 12v+ wire is brown/red, the ground wire is black, and the illumination wire is blue/black. For the front speakers, the left front speaker wire (+) is white/red, the left front speaker wire (-) is white/green, the right front speaker wire (+) is yellow/red, and the right front speaker wire (-) is yellow/blue. For the rear speakers, the left rear speaker wire (+) is red/green, the left rear speaker wire (-) is red/black, the right rear speaker wire (+) is green/red, and the right rear speaker wire (-) is green/yellow.
Can a 220-4 wire cord be reduced to 3 wire?
When flexible cords are talked about the ground wire is in the conductor count. A four wire cord will have black, red, white, and green coloured wires in the flexible cable set. A three wire cord will have a black, white and green coloured wires in the cable set. To use a four wire cord to carry 220 volts just use the black, red and green wires. Connect to the cord ends. Black and red to the outside blade terminal screws and the green wire to the green ground screw. To use a three wire cord to carry 220 volts just use all of the wires. Black and white to the outside blade terminal screws and the green wire to the green ground screw.
