Frequently Asked Questions
Common questions about NEMA NEMA L23-20P cords and connectors
The NEMA L23-20P is a NEMA locking connector rated 20 A at 347/600 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 L23-20R.
The 20 A 347/600 V three-phase wye NEMA L23-20P is typically used for locking 600 V-class wye distribution needing a neutral for 347 V line-to-neutral lighting or controls in heavy industrial facilities. Selecting the correct 20 A 347/600 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 L23-20P 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 L23-20R female receptacle (socket-outlet or cord connector). It carries 20 A at 347/600 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 L23-20P mates only within its own 20 A 347/600 V three-phase wye family. The 5-wire L23 is keyed for 347/600 V and will not mate with the 4-wire L20 or lower-voltage L21/L22 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 L23-20P 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.
