Frequently Asked Questions
Common questions about NEMA NEMA 15-50P cords and connectors
The NEMA 15-50P is a NEMA connector rated 50 A at 250 V three-phase, 3-pole, 4-wire (grounded, no neutral), for three-phase circuits. It uses the standard NEMA non-locking straight-blade configuration. The trailing P identifies it as a male plug; it pairs only with the matching NEMA 15-50R.
The 50 A 250 V three-phase NEMA 15-50P is typically used for three-phase 250 V industrial equipment, motors and machinery in North American facilities. Selecting the correct 50 A 250 V three-phase 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 15-50P is the male plug, typically fitted on the end of a power cord or equipment inlet lead, and it only mates with a matching NEMA 15-50R female receptacle (socket-outlet or cord connector). It carries 50 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 50 A.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA 15-50P mates only within its own 50 A 250 V three-phase family. The 15-series carries three phase conductors plus ground with no neutral and cannot mate with single-phase 5/6-series or other three-phase 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 15-50P 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.
