What color wire is used for grounding according to LA City code?

• A. Red
• B. Blue
• C. Green
• D. Yellow

Answer: (C)

Grounding is a critical component of electrical systems, ensuring safety by providing a path for electrical current to flow safely to the ground in the event of a fault. According to the Los Angeles City code, and generally in electrical wiring standards, the color green is used for grounding wires. This standardized color coding helps electricians and technicians easily identify and perform safe connections during installations and repairs.

By using green for grounding, it reduces the risk of confusion with other wires, thus improving the overall safety and reliability of electrical systems. Other colors, such as red, blue, and yellow, are designated for different purposes, such as power conductors or signal wires, which further distinguishes their respective roles in an electrical circuit.
