Which color is typically used to indicate a grounded conductor?

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

Answer: (C)

The color that is typically used to indicate a grounded conductor is white or grey. In electrical wiring practices, particularly within the context of the National Electrical Code (NEC), white or grey is designated for use as the neutral wire, which is a grounded conductor. The neutral wire carries current away from the load and returns it to the electrical panel, ensuring a complete circuit. The importance of identifying the neutral wire cannot be overstated, as it helps to ensure safety and proper functioning of electrical systems. Grounded conductors are essential for preventing electrical shock and protecting equipment from overheating or malfunctioning due to faults. Understanding this color coding is crucial for anyone working in the field of electrical installation or maintenance, including those with a Texas Residential Appliance Installer License. Other colors are assigned specific uses in electrical systems: for instance, black and red are typically used for hot wires, which carry current to appliances, while green is designated exclusively for grounding conductors. Such distinctions help maintain safety standards and ensure proper connections are made during installation.
