Electric live wire color.

This color of wire is used to transfer power to switches and outlets in all types of circuits. The purpose of the green wire is to provide a path to ground for a circuit s electric current if a live wire within the circuit happens to touch metal or some other conductive material. Canada ac power circuit wiring. The outer plastic sheathing or jacket and the inner color coded wires the sheathing binds the inner wires together and its outer markings indicate the number of wires and size of wire gauge within the sheathing.

Earth wire neutral wire live wire line 2 wire line 3 electrical wire. The neutral is white the hot live or active single phase wires are black and red in the case of a second active. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability with further restrictions on the. For three phase electricity supply circuits will use five wires.

Electrical wiring is an electrical installation of cabling and associated devices such as switches distribution boards sockets and light fittings in a structure. Three phase lines are red black and blue. Wiring is subject to safety standards for design and installation. In the event of a fault it could carry significant current so treat green wires cautiously.

This article details the following cable colour codes. Wiring colour codes for ac and dc power distribution circuits have changed on numerous occasions and vary depending on region. The color of the sheathing indicates recommended. Non metallic or nm 120 volt and 240 volt electrical cable come in two main parts.

Also black wires are often used as switch legs in circuits which is the connection linking a switch to the electrical load. The protective ground is green or green with yellow stripe.
