What is the color code for 120 208v 3-phase?
AC Power (120/208/240 Volts) Phase 1 – Phase 1 wiring should be black. Phase 2 – Phase 2 wiring should be red. Phase 3 – Phase 3 wiring should be blue. Neutral – Neutral wiring should be white.
What color wires are 208?
International Wiring Color Codes The USA has their own wiring colors for electrical circuits, black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC.
What is the color code for 120 volt?
While the NEC does not contain a required color code for voltage marking, the industry standard is 208/120V (A) black, (B) red, (C) blue and grounded/neutral white; 480/277V (A) brown, (B) orange, (C) yellow and grounded/neutral gray.
What are the 3 phase Colours?
For three-phase cables the phase colours are brown, black and grey, instead of red, yellow and blue, respectively, and the neutral colour is now blue instead of black. Again the protective conductor is identified by the colour combination green-and-yellow.
What is the wiring color code?
US AC power circuit wiring color codes 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.
What color is hot wire in a 120 volt circuit?
black wire
Hot: The black wire is the hot wire, which provides a 120 VAC current source. Neutral: The white wire is called the neutral wire. It provides the return path for the current provided by the hot wire.
What color is neutral wire 120V?
Black, Red and Blue are used for hot wires and White is used as the neutral wire in a 120/208 V circuit. Brown, Orange and Yellow are used as hot wires and gray is used as the neutral wire in a 277/480 V.
What are the phases of a 120 208 volt circuit?
In commercial 120/208 volt electrical systems, there are three phases – A, B, and C. Each phase is one of three colors – black, red, or blue. Phase A is circuit 1 and 2 (black), Phase B is circuit 3 and 4 (red), Phase C is circuit 5 and 6 (blue). It then starts over with the phases.
What are the colors of 240 volt wire?
120/208/240 Volt AC Wire Colors. 1 Phase 1 – Black. 2 Phase 2 – Red. 3 Phase 3 – Blue. 4 Neutral – White. 5 Ground – Green, Green with Yellow Stripe, or Bare Wire.
Can I use 120/208 appliances on a 120/240 volt system?
Appliances and equipment rated for 120/208 volts but not 120/240 volts may generally not be used on a 120/240 volt system or on a system that measures 110/220 volts. (Some analysis would need to be done to see if a particular item would work.) Electrical: Available in 120/208 single phase, 120/220 single phase, or 120/240 single phase.
What is the standard color of 480 volt wire?
277/480 Volt Wire Color Standards Phase 1 – Phase 1 wiring should be brown. Phase 2 – Phase 2 wiring should be orange. Phase 3 – Phase 3 wiring should be yellow. Neutral – Neutral wires should be grey. Ground – Ground wiring should be green, or green with a yellow stripe.
