About NEMA Plugs, Sockets, and Receptacles

Ground-Monitoring Turn-Lock Plugs and Sockets

Check the status of a ground connection—a green light signals that connectors have power and are safely grounded. A red light indicates power only. The lights are visible from any angle for quick identification. A quarter turn locks connectors in place to remain secure in high-vibration applications and prevent accidental disconnection.
