120/208/240 Volt AC Wire Colors
These systems are common in home and office environments.>
Phase 1 - Black
Phase 2 - Red
Phase 3 - Blue
Neutral - White
Ground - Green, Green with Yellow Stripe, or Bare Wire
If the wiring system has one phase at a higher voltage than the others, using a “high-leg” connection, that phase’s wires should be marked with orange. (This is required in NEC article 110.15.) However, these high-leg delta systems are uncommon with newer installations.
