If provided, the AC grounding conductor pigtails must be what color?

The grounding conductor pigtails for AC systems are appropriately designated as green or green with a yellow stripe. This color coding is critical for identifying grounding conductors in electrical installations, as it helps ensure safety and compliance with standards set forth by the American Boat and Yacht Council (ABYC) and the National Electrical Code (NEC).

Grounding conductors are vital for preventing electrical shock and ensuring proper circuit operation. By following this color code, technicians and inspectors can quickly identify grounding wires during installation, maintenance, and troubleshooting, reducing the risk of errors and enhancing overall safety.

The other options, such as red, black, blue, and yellow or brown, are typically associated with different functions in electrical systems, such as hot conductors or specific circuits, but they do not conform to the conventions for grounding conductors. Adhering to the recognized standards is essential for maintaining safe and reliable electrical systems in marine environments.
