Frequently Asked Questions
Common questions about NEMA NEMA L22-20P cords and connectors
The NEMA L22-20P is a NEMA locking connector rated 20 A at 277/480 V three-phase wye, 4-pole, 5-wire (grounded, with neutral), for three-phase wye 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 L22-20R.
The 20 A 277/480 V three-phase wye NEMA L22-20P is typically used for locking 480 V wye distribution needing a neutral for 277 V line-to-neutral lighting or controls alongside three-phase loads. Selecting the correct 20 A 277/480 V three-phase wye locking connector ensures the contacts and cable can carry the load without overheating and that the three-phase wye supply is connected with the proper grounding and polarity.
The NEMA L22-20P 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 L22-20R female receptacle (socket-outlet or cord connector). It carries 20 A at 277/480 V three-phase wye in a 4-pole, 5-wire (grounded, with neutral) 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 L22-20P mates only within its own 20 A 277/480 V three-phase wye family. The 5-wire L22 includes a neutral and cannot mate with the 4-wire L19 or with 208 V L21 connectors. 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 L22-20P 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.
