Frequently Asked Questions
Common questions about NEMA NEMA 15-50R cords and connectors
The NEMA 15-50R 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 R identifies it as a female receptacle; it pairs only with the matching NEMA 15-50P.
The 50 A 250 V three-phase NEMA 15-50R 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 15-50R is the female receptacle (socket-outlet or cord connector) and accepts only the matching NEMA 15-50P male plug. It is rated 50 A at 250 V three-phase in a 3-pole, 4-wire (grounded, no neutral) configuration, and it supplies power to the connected cord or equipment only when the correctly keyed 50 A plug is inserted.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA 15-50R 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 15-50R 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.
