Frequently Asked Questions
Common questions about NEMA NEMA L6-20P cords and connectors
The NEMA L6-20P 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 P identifies it as a male plug; it pairs only with the matching NEMA L6-20R.
The 20 A 250 V NEMA L6-20P 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 L6-20P is the locking male plug, typically fitted on the end of a power cord or equipment inlet lead, and it only mates with a matching NEMA L6-20R female receptacle (socket-outlet or cord connector). It carries 20 A at 250 V in a 2-pole, 3-wire (grounded) configuration, so the outlet, wiring and overcurrent protection must all be rated for at least 20 A.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA L6-20P 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 L6-20P 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.
