What color insulation typically indicates a ground wire in electrical wiring?

• A. Red
• B. Blue
• C. Green or bare copper
• D. Black

Answer: (C)

The color insulation that typically indicates a ground wire in electrical wiring is green or bare copper. This is in accordance with national and international wire color codes designed to ensure safety and standardization in electrical installations. Ground wires are crucial for safety, providing a path for electrical current to safely dissipate into the ground in the event of a fault. Using green insulation or bare copper helps distinguish these wires from others, reducing the risk of confusion during installation or maintenance. The clear identification of ground wires is essential for the safe operation of electrical systems, as it ensures that anyone working on or around the wiring can easily identify the ground connection, minimizing the risk of electrical shock or equipment damage.
