What are the standard color codes for hot conductors on a typical 120/240V circuit?

Explanation:
In U.S. residential wiring, two hot legs come from a 120/240V supply, and they are color-coded to distinguish their roles. The two hot conductors are black and red, each carrying 120V relative to neutral, and 240V between them. The neutral conductor is white, returning current from 120V loads. Green or bare conductors are used for grounding, not as hot or neutral. So the standard pairing for hot conductors on a typical 120/240V circuit is black and red as hot, with white as neutral.
