An 8 AWG insulated grounded conductor shall be identified by which of the following means?

The identification of an 8 AWG insulated grounded conductor is critical for ensuring proper electrical safety and compliance with wiring standards. The standards for identifying grounded conductors allow for several options: a continuous white outer finish, a continuous gray outer finish, or three continuous white or gray stripes.

These identification methods are designed to make the recognition of grounded conductors clear and intuitive for anyone working with or around electrical systems. A continuous white outer finish is the most common designation for grounded conductors in the National Electrical Code (NEC), but the option for a gray finish or the striped pattern provides needed flexibility for situations in which white might not be practical due to other design considerations.

Thus, because all three identification methods are valid and compliant with the guidelines, referring to the option that includes all of these means correctly encompasses the range of acceptable identification practices for an 8 AWG insulated grounded conductor. This ensures clarity and safety in electrical installations.
