Frequently Asked Questions
Common questions about NEMA NEMA L15-20P cords and connectors
The NEMA L15-20P is a NEMA locking connector rated 20 A at 250 V three-phase, 3-pole, 4-wire (grounded, no neutral), for three-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 L15-20R.
The 20 A 250 V three-phase NEMA L15-20P is typically used for locking three-phase 250 V industrial equipment, motors, portable distribution and stage power. Selecting the correct 20 A 250 V three-phase locking connector ensures the contacts and cable can carry the load without overheating and that the three-phase supply is connected with the proper grounding and polarity.
The NEMA L15-20P 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 L15-20R female receptacle (socket-outlet or cord connector). It carries 20 A at 250 V three-phase in a 3-pole, 4-wire (grounded, no 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 L15-20P mates only within its own 20 A 250 V three-phase family. The L15 carries three phases plus ground at 250 V and cannot mate with single-phase L6-250 V or other three-phase voltage families. 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 L15-20P 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.
