A grounded conductor larger than 6 AWG must be identified using which of the following methods?

A grounded conductor larger than 6 AWG must be identified as either a bare conductor or one that has a continuous white or gray finish. This identification is crucial for safety and clarity in electrical installations. By using these color designations, individuals working with or near electrical systems can quickly recognize the conductor's purpose and avoid potential hazards.

The reason bare conductors or those finished in white or gray are specified is to ensure clear and consistent identification across various installations. It helps distinguish grounded conductors from other types of conductors, which may be insulated with different colors representing different functions or voltages.

The other identification methods, like colored tape wrap or any insulation color, may not provide the specific and uniform standard required for larger grounded conductors. Continuous green or yellow markings are typically reserved for grounding conductors, not specifically for identifying grounded conductors larger than 6 AWG. Therefore, adhering to the bare conductor or continuous white or gray finish ensures both compliance with safety standards and enhances operational clarity within electrical systems.
