Frequently Asked Questions
Common questions about NEMA NEMA 7-20P cords and connectors
The NEMA 7-20P is a NEMA connector rated 20 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 7-20R.
The 20 A 277 V NEMA 7-20P 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 20 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 7-20P 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 7-20R female receptacle (socket-outlet or cord connector). It carries 20 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 20 A.
No. NEMA connectors are keyed by voltage, current, phase and grounding, so the NEMA 7-20P mates only within its own 20 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.
