How should pigtails, specifically for AC grounding conductors, be configured?

Grounding conductors are essential for ensuring safety in electrical systems, and the color coding helps to identify these conductors for proper installation and maintenance. The correct configuration for pigtails used specifically for AC grounding conductors is indicated by the green color or green with a yellow stripe.

Green is universally associated with grounding in electrical installations. This standardization is crucial because it helps technicians and electricians quickly recognize grounding conductors, reducing the risk of error during maintenance or installation work. The addition of yellow stripes does not change the conductor's purpose as a grounding element; it merely adds a visual indicator as an extra layer of identification in certain installations.

In essence, using the correct color coding for grounding conductors enhances safety and compliance with electrical codes, allowing individuals working with these systems to easily distinguish between various types of wiring, especially in complex AC installations.
