NEMA 7-30R 277V receptacle

This NEMA 7-30R female socket is rated for 30 amps at 277 volts AC. It is a rewireable connector intended for older equipment that uses this specific locking configuration. The ETL-certified device suits industrial welders and dryers requiring a heavy-duty power inlet.

Extra strain-relief fittings

Two additional strain-relief bushings are supplied so the cord and socket join securely. The housing is moulded from nylon rated UL 94-V0 and meets RoHS and REACH substance restrictions. Terminals are marked X, Y, Z for line, W for grounded and G for grounding conductors.

Questions about this item

Will the plug shell cover or metal pins need replacement after repeated wiring?

The plug shell cover uses Nylon UL 94-V0 rated material and the metal pins are pure copper; both are built for repeated rewireable use and no scheduled replacement is indicated.

What is the maximum continuous current the receptacle can handle with 11 or 12 AWG cord?

The rating drops to 25 amps at 277 volts when using 11 or 12 AWG cord, so sustained loads above that level will hit the limit first.

How much heat does the receptacle generate during all-day operation at full load?

The housing meets UL 94-V0 flame rating and the terminals are pure copper, which minimises resistive heating; no specific temperature-rise figure is published.
