Frequently Asked Questions
Common questions about NEMA NEMA L6-20R cords and connectors
The NEMA L6-20R is a NEMA locking connector rated 20 A at 250 V, 2-pole, 3-wire (grounded), for single-phase circuits. The L-prefix indicates a twist-locking connector that must be inserted and rotated to secure it, preventing accidental disconnection under vibration. The trailing R identifies it as a female receptacle; it pairs only with the matching NEMA L6-20P.
The 20 A 250 V NEMA L6-20R is typically used for locking 250 V power for welders, stage lighting, motors and industrial equipment subject to movement or vibration. Selecting the correct 20 A 250 V locking connector ensures the contacts and cable can carry the load without overheating and that the single-phase supply is connected with the proper grounding and polarity.
The NEMA L6-20R is the locking female receptacle (socket-outlet or cord connector) and accepts only the matching NEMA L6-20P male plug. It is rated 20 A at 250 V in a 2-pole, 3-wire (grounded) configuration, and it supplies power to the connected cord or equipment only when the correctly keyed 20 A plug is inserted.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA L6-20R mates only within its own 20 A 250 V family. The L6 is the twist-lock 250 V counterpart of the straight-blade 6-series and cannot mate with 125 V L5 connectors; voltage and blade keying differ. When two configurations must be joined, use a properly rated, UL-listed adapter or cord set, and never exceed the lowest current rating in the chain.
Yes. We manufacture UL/cUL and ETL listed NEMA L6-20R cord sets, rewireable plugs and receptacles, and molded connectors using RoHS, REACH, PAHS and Proposition 65 compliant cable, with custom lengths, wire gauges, jacket colors, strain relief and labeling. MOQ is typically 200-1000 pieces, samples ship in 7-15 days and bulk production takes 15-20 working days.
