Electrical Wire Color Codes Wiring Colors Chart Electrical Wiring 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. The mandatory colors for power wiring in national electric codes (nec) are green, bare or green yellow (yellow strip or band on green) for protective ground “pg” and white (alternatively grey) for neutral wire. any other colors expected the above mentioned can be used for live (line or hot) wires.
Electrical Wiring Color Code Standards Neutral – gray wire. ground – green, green with yellow stripe, or bare wire. when powering higher voltage devices, be sure you are labeling wires and cables accurately and add safety signs, where needed. this identification can be used during a lockout tagout, should the equipment need to be de energized. Ac wire colors for 120 208 240 volts. these are commonly found in home and office settings. phase 1 black phase 2 red phase 3 blue neutral white ground green, green with yellow stripe, or bare wire. if one phase of your wiring is at a higher voltage than others, using a high leg connection, wires should be marked orange for that phase. 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. United states: in the united states, the standard color code for electrical wiring is typically black, red, blue, white, green, and bare copper. black is used for hot wires, red for second hot wires, blue for neutrals, white for grounded wires, green for grounding, and bare copper for grounding as well. united kingdom: in the united kingdom.

United states: in the united states, the standard color code for electrical wiring is typically black, red, blue, white, green, and bare copper. black is used for hot wires, red for second hot wires, blue for neutrals, white for grounded wires, green for grounding, and bare copper for grounding as well. united kingdom: in the united kingdom. The most commonly used color codes in wiring diagrams are: black: used for power or hot wires. red: typically used as a secondary hot wire or for switch legs. blue: commonly used for travelers in three way switch wiring. green: represents grounding and is used for grounding wires. white or gray: used for neutral wires and grounded conductors. Yellow. canada: canadian wiring is governed by the cec (canadian electric code). see table below. the protective ground is green or green with yellow stripe. the neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. three phase lines are red, black, and blue.
