NEMA L6-20R Twist Lock Receptacle

This receptacle provides a secure 20 amp 250 volt connection for industrial equipment and generators. It is designed for users who need to repair or build heavy-duty extension cords and power cables in commercial or workshop settings.

ETL Certification and Rewireable Design

The unit complies with UL498 and CSA C22.2#42 standards and carries an ETL listing for safety assurance. Its split screw-fixed housing accepts 10 to 18 AWG three-conductor cables, allowing damaged cord ends to be replaced without discarding the entire cable length.

UL94-V0 Nylon Housing and Copper Contacts

The fire-resistant nylon body and solid copper terminals resist heat and maintain low resistance under continuous rated loads. The twist-lock mechanism mates exclusively with NEMA L6-20P plugs to prevent accidental disconnection, while clearly marked X, Y, and G terminals simplify standardized wiring for high-voltage applications.

Questions about this item

Will the screw terminals on this L6-20R need re-torquing after extended use?

The split screw-fixed housing uses solid copper terminals with low resistance and effective heat dissipation, designed to sustain stable performance under continuous rated load without routine re-torquing.

What is the continuous current limit before the 250 V rating is derated?

The receptacle is rated 20 A at 250 V (maximum 5000 W); with 10–12 AWG conductors it carries the full 20 A, with 13–14 AWG it is limited to 18 A, and with 15–16 AWG to 13 A.

Does the UL94-V0 nylon housing stay cool enough for all-day generator runs?

The vertical-rib anti-slip nylon housing is UL94-V0 fire-resistant, and the solid copper contacts provide effective heat dissipation to maintain stable performance under continuous rated load.
