Which color is designated for grounding conductors?

Red
Black
Green
White

The correct answer is: Green

The color designated for grounding conductors is green. This standard is established to promote safety and avoid confusion within electrical systems. Grounding conductors are crucial because they provide a safe path for electrical current to return to the ground in case of a fault, preventing electric shock or fire hazards. Using a specific color, such as green, for grounding conductors helps electricians and others working with electrical systems easily identify these wires. This clear visual differentiation ensures that safety protocols are followed and reduces the chance of accidental mishaps during installation or maintenance. The use of green for grounding is recognized in various electrical codes and standards, including the National Electrical Code (NEC) in the United States, which reinforces this practice across many applications in electrical engineering and installation.
