What is the standard color for an equipment grounding conductor?

• A. Red
• B. Blue
• C. Green or green with a yellow stripe
• D. Black

Answer: (C)

Grounding conductors use green, or green with a yellow stripe, to signal they are the equipment grounding path. This color coding helps electricians quickly identify the wire whose role is to carry fault current safely back to the earth so protective devices can trip and prevent shock. Other colors are used for live or neutral conductors (hot wires are typically black, red, or blue; neutral is white or gray), so green or green/yellow stands out as the dedicated grounding color. If you see bare copper, that can also serve as a grounding path, but when insulation is present, the standard color is green or green with a yellow stripe to indicate grounding.
