Summary: Electrical wire colors for most typical home electrical wiring. The chart below includes UK electrical wire, EU electrical wire, Australia electrical wire, New Zealand electrical wire, South Africa electrical wire, Canada electrical wire and United States electrical wire.
The Electrical Wire Identification System
To enable wires to be easily and safely identified all common wiring safety codes follow a structured color scheme for the insulation of electrical wire.
There are local rules and exceptions that exist based upon the exact application.
Many older wire installations may vary in color codes, and color may fade or change with heat and age of insulation.
such as Extension cords, power (line) cords and lamp cords
