Frequently Asked Questions
Common questions about NEMA NEMA 6-20R cords and connectors
The NEMA 6-20R is a NEMA connector rated 20 A at 250 V, 2-pole, 3-wire (grounded), for single-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 6-20P.
The 20 A 250 V NEMA 6-20R is typically used for 250 V equipment such as welders, plasma cutters, compressors, large air conditioners and industrial machines. Selecting the correct 20 A 250 V connector ensures the contacts and cable can carry the load without overheating and that the single-phase supply is connected with the proper grounding and polarity.
The NEMA 6-20R is the female receptacle (socket-outlet or cord connector) and accepts only the matching NEMA 6-20P male plug. It is rated 20 A at 250 V in a 2-pole, 3-wire (grounded) configuration, and it supplies power to the connected cord or equipment only when the correctly keyed 20 A plug is inserted.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA 6-20R mates only within its own 20 A 250 V family. 6-series connectors are keyed for 250 V and will not mate with 125 V 5-series connectors, preventing a dangerous voltage mismatch. As a 20 A T-slot receptacle, the NEMA 6-20R also accepts the lower-amperage NEMA 6-15P plug in addition to the NEMA 6-20P. 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 6-20R 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.
