Frequently Asked Questions
Common questions about NEMA NEMA 7-50P cords and connectors
The NEMA 7-50P is a NEMA connector rated 50 A at 277 V, 2-pole, 3-wire (grounded), for single-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 7-50R.
The 50 A 277 V NEMA 7-50P is typically used for 277 V commercial and industrial lighting circuits commonly found in North American warehouses, retail and office buildings fed from 480Y/277 V systems. Selecting the correct 50 A 277 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 7-50P 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 7-50R female receptacle (socket-outlet or cord connector). It carries 50 A at 277 V in a 2-pole, 3-wire (grounded) 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 7-50P mates only within its own 50 A 277 V family. The 277 V 7-series is specific to 480Y/277 V commercial lighting and cannot be interchanged with 125 V, 250 V or 480 V 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.
