Blue and Yellow colour wires are also used in connecting live wires. These wires are used in hot wiring and three-phase connections. Yellow wires are used in switch wiring and connected to fans, tube lights, and other electrical appliances.
What is black wire?
Black wires are neutral wires in the electric circuit that carries the unbalanced load or unused current back to the electric panel. Black wires are not meant to be connected with other wires except black wires.
What is green wire?
Green Wires. Green electrical wires are used for grounding. They provide a safe pathway for current to travel to the ground in case of any fault occurrence. Green wires are not intended to use for lights and fans. They are attached to appliances like AC, TV, microwaves and geysers to provide earthing in an electrical circuit.
Why do electricians use colors?
The colours allow electricians or electrical workers to identify and work with wires without any danger. While dealing with electrical wires, one should follow some safety measures and the colour codes of wires will help in installing correctly.
Why do we need to know the wiring colour?
As electricity plays a vital role in our daily lives so, everyone should have minimum knowledge about wire colours and wire installations. The electrical wiring colour codes have created to ensure safety and convenience. The colours allow electricians or electrical workers to identify and work with wires without any danger.
Do electrical wire colors matter?
Electrical wire colours do matter when performing electrical works or any wiring installations in residential, commercial and industrial buildings. As electricity plays a vital role in our daily lives so, everyone should have minimum knowledge about wire colours and wire installations.
What color wires are used for three phase?
Even there are different color codes for AC and DC wires. For example, in Canada, you can find Red, black and blue wires for three-phase, whereas, in Australia, it is Yellow, blue and black.
What color is the NEC standard?
NEC mandates the color codes for neutral and protective ground as grey and yellow-green respectively. NEC does not instruct any requirements for other conductors.
What colors are used for a three phase supply?

A brief history of wiring color codes
It took until 1928 for wire color coding to make its debut. The National Electrical Code® (NEC) was the first to reference it, and today continues to set the standards for the electrical industry. Following a uniform color code makes it easier to assess electrical wiring, and ensure safety among licensed professionals and homeowners alike.
The NEC wire color coding standards
Though there are international wire color codes, the U.S. follows the National Electrical Code ® (NEC). The code is identified as NFPA 70 ® because the NEC is sponsored by the National Fire Protection Association. Though not a federal law (states can choose to adopt it), it is approved by the American National Standards Institute (ANSI).
