Electrical Wiring Colour Code Home Wiring Diagram Canada wiring colours, as regulated by the canadian electrical code (cec), are quite similar to the national electrical code (nec) in the united states. you don’t need to be a rocket scientist – or an electrician – to know and understand, that the specific colouring of the electrical wires in your home means something. Electrical wire colour code. the colour of a wire tells you the best use for it. white wires are usually neutral wires, green or bare wires are ground wires, and any other color is usually hot (carrying a current). in existing wiring jobs, white wires may also be marked with black or red to indicate that it’s now a hot wire.

House Wiring Color Code Rounding out the electrical wire color code are orange, brown, pink and violet. in u.s. homes, orange is most commonly used like a red wire, particularly in a 240 volt circuit where two hot wires are needed. you might see orange wires in the fire alarm circuit as well. pink and violet are less prevalent but can be used as travelers or switch. Wire color codes are black, red, white, bare copper, green, white or gray, and blue or yellow. white, gray, bare copper, and green are the only wire colors that the nec mandates must indicate a specific purpose. white or gray must be used for neutral conductors. bare copper or green wires must be used as ground wires. The wire color code is helpful in preventing errors and assesing and remembering existing wiring. most importantly, color coding adds an element of safety when connecting wires. electrical wires can be hot, neutral, or ground, and has a corresponding color to denote this. the most common colors you'll find in home wiring include black, red. Line (l) = black or red. neutral (n) = white. protective earth (pe) = green, green yellow striped. fixed cable. the wire color codes from this category are 3 phase color charts, all of the cable behind the wall, in the wall, or on the wall. 120, 208, 240 v line voltage wire color code: three phase, line 1 (l1) = black.
