Agricultural Mechanics 2 EOPA Practice Test

In standard electrical color coding, which color indicates ground?

White Black Copper Green

Correct Answer:

Copper

Explanation:

Ground is indicated by green (often green-yellow) in standard electrical color coding. This color is reserved for the equipment grounding conductor to signal a safety path for fault current. White is neutral, and black is hot/live. Copper is a common grounding material, especially when bare, but color coding uses green to identify ground. So green is the correct color.
