Every twine used for electric wiring is marked with records like twine gauge, ampacity, most voltage, and most temperature. However a standard coloration code is used to perceive one-of-a-kind styles of conductors which are utilized in electrical wiring.
Relying at the segment of the energy supply, unique wire color are used for specific voltages. In case of a single segment power deliver, there are three wires one every for line, neutral and shielding floor.
With the help of electrical wire color, they can be without difficulty and thoroughly recognized. there are a few protection measurements which can be to be followed at the same time as dealing with electrical wiring and the wire colors will help in enforcing those protection measurements as a unmarried code is accompanied in that specific jurisdiction.

In three phase power deliver, the combination of black, pink and blue wires for electricity conductors are used for a hundred and twenty/240v ac whereas the aggregate of brown, orange and yellow wires for energy conductors are used for 277/480 v ac.
In case of unmarried phase strength deliver, black twine is used as the road cord and in case of 220v deliver, pink cord is used because the secondary line conductor.
