Electrical Wiring Color Codes Important
There are two color codes available in the United States for different voltages For 1/8/240 V single phase, the live cable is lack or red, the neutral cable is white colored while the protective earth can be green, bare or striped green and yellow in color Cletis said wasnt' talking about those circuits just 8 and 480 single phase Click to expand If there's just 8, you can use whatever color you want If you have just 480 you can use whatever color you want If you have both, then you need toPhase 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 highleg connection, wires should be marked orange for that phase Highleg connections are typically uncommon in newer installations
Gray or with 2 white stripes;Please follow the National Electric Codes ie NEC wiring color codes or other local area color codes For 1V, 8V & 240V, 1phase and 3phase circuits, we have used the NEC general practice wiring color codes as follows Blue = Hot 1 or Line 1 A 8V 3 Phase Power Panel provides 3 power circuit types (1V 1 Phase, 8V 1 Phase, 8V 3 Phase) in 7 circuit configurations based on Circuit Breaker (CB) Type (1 Pole, 2 Pole, 3 Pole) and Position (1, 2, 3, etc) as shown below Single Phase 1V – 1 Pole Circuit Breaker 1V 1 Phase (Phase A, Neutral) 1V 1 Phase (Phase B, Neutral)
I think the color markings would be blk/ rd/ org Before the code required the High Leg to be marked Orange it was always marked Blue I have never seen a High Leg marked Red around here We have a lot of Open Delta 3 phase services around here The power Co can get away with running 2 primary phases to a 3 phase location, use 2 pots and hook them up in an open delta configThe main service coming into the building will be 277/480 volts 3phase 4wire Wye This voltage can be broken down in the building very simply with a 3phase step down transformer A 25 kva, 1/8 3phase 4wire Wye transformer can be used to furnish all the 1 volts needed in the small office and warehouse
