Which color wire is typically used for grounding in electrical systems?

• A. Black
• B. Green
• C. White
• D. Red

Answer: (B)

In electrical systems, the color green is universally recognized for grounding wires. Grounding wires are crucial as they provide a path for electric current to safely dissipate into the earth in the event of a fault, ensuring safety for both the electrical system and any individuals who might come into contact with it. Using green for grounding helps to maintain consistency and avoid confusion during the installations and repairs of electrical systems. This color-coding is followed in most wiring practices and codes, making it important for electricians and anyone involved in electrical work to identify the grounding wire quickly and accurately. The other colors listed have specific purposes: black is typically used for hot wires, white is used for neutral wires, and red can be used for secondary hot wires in circuits. By understanding these color designations, those working with electrical systems can ensure safer and more efficient installations.
