What method is permitted to identify equipment grounding conductors of sizes 4 AWG and larger?

• A. Labeling with a tag
• B. Color coding the insulation
• C. Stripping the insulation
• D. Using a separate wire

Answer: (C)

When it comes to identifying equipment grounding conductors that are 4 AWG and larger, stripping the insulation is an acceptable method. This practice allows for a clear and unambiguous way to recognize the conductor. By removing a section of the insulation, the ground wire becomes easily identifiable in the context of other conductors, minimizing the chances of any mix-up during installation, maintenance, or inspections. The requirement to identify larger conductors is crucial because these sizes are commonly involved in critical safety practices, and any misunderstanding could lead to significant safety hazards. Stripped insulation provides a practical approach without needing additional materials or colors, making it efficient and effective.
