Twist-lock connector body · 15A 250V NEMA L6-15R 2P3W safety grip · Cooper Wiring Devices CWL615C
15A 250V NEMA L6-15R locking connector body for 2-pole 3-wire applications. Industrial grade nylon construction with back wiring and a safety-grip body, sized for approximately 0.38 to 1.00 in cord OD (about 9.7 to 25.4 mm).
What this product is for
This locking connector body is used to terminate flexible cord on 250V 2-pole 3-wire equipment and extension leads that require a NEMA L6-15R connection. It is commonly selected for portable equipment, generators, HVAC service connections, and other industrial power applications where a twist-lock connection helps resist accidental unplugging.
Use for
Use for 15A, 250V locking cord-end connections with NEMA L6-15 plugs. Suitable for cord sizes using conductors from #16 to #12 AWG and cable outside diameters from approximately 0.38 to 1.00 in (9.7 to 25.4 mm).
Avoid for
Avoid using this connector where a straight-blade configuration is required, where the mating device is not NEMA L6-15, or where wet-location protection is required without a properly rated enclosure or cover.
Best for
Best for electricians and maintenance teams needing an industrial grade locking connector with a cord grip body for portable 250V loads. The twist-lock pattern helps reduce disconnects caused by vibration or cord movement.
Installed in
Typically installed on flexible power cords for shop equipment, compressors, pumps, HVAC service tools, and other 250V portable loads in commercial and industrial settings.
Why this product exists
This product provides a field-installable female locking cord end for L6-15 applications, giving a more secure connection than a non-locking cord cap. It also accommodates a practical cord range for service and equipment leads.
Compared with similar products
Compared with a standard straight-blade connector, an L6-15R locking connector is chosen when the plug must stay engaged during movement or vibration. Compared with higher-amperage locking devices, this 15A version is intended for lighter 250V branch-circuit loads and matching 15A configurations only.
