Frequently Asked Questions
Common questions about NEMA NEMA SS2-50R cords and connectors
The NEMA SS2-50R is a NEMA locking connector rated 50 A at 125/250 V, 3-pole, 4-wire (grounded), for split-phase circuits. The SS (shore ship) connector uses a threaded twist-locking ring that is tightened after insertion to prevent accidental disconnection and seal the connection on boats and RVs. The trailing R identifies it as a female receptacle; it pairs only with the matching NEMA SS2-50P.
The 50 A 125/250 V NEMA SS2-50R is typically used for 50 A shore power for large yachts and 50 A RV/motorhome service, delivering two 125 V legs and 250 V across four wires. Selecting the correct 50 A 125/250 V locking connector ensures the contacts and cable can carry the load without overheating and that the split-phase supply is connected with the proper grounding and polarity.
The NEMA SS2-50R is the locking female receptacle (socket-outlet or cord connector) and accepts only the matching NEMA SS2-50P male plug. It is rated 50 A at 125/250 V in a 3-pole, 4-wire (grounded) 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 SS2-50R mates only within its own 50 A 125/250 V family. The SS2-50 twist-lock marine connector is the 50 A 125/250 V standard; it is mechanically different from the straight-blade NEMA 14-50 even though both are 50 A 125/250 V. 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 SS2-50R 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.
