  • ETL listed for safety compliance with UL 498 and CSA 22.2 standards
  • Twist-lock design prevents accidental disconnection from mating L7-30P plug
  • Rated 30 A at 277 V for 10 AWG cord and 25 A for 11-12 AWG cord
  • Terminals marked X, Y, Z, W, G for clear wiring identification
  • Industrial-grade construction with heavy-duty conducting materials for durable performance

Industrial locking socket for 277 V generators

The LORDWORLD NEMA L7-30R is a new ETL-listed female connector rated 30 A at 277 V AC. Its twist-lock design mates only with a matching NEMA L7-30P plug, and the rotated T-shaped blade prevents accidental insertion into incompatible locking outlets. Terminal markings X, Y, Z, W and G guide correct wiring for line, grounded and grounding conductors.

Cord capacity and ampacity limits

The connector accepts 10 AWG three-conductor cord at the full 30 A 277 V rating and 11 or 12 AWG cord at 25 A 277 V. A long list of service-grade cable types from SJT through STOOW and SJEOOW is supported. Installers must match conductor size to the intended load; the device does not increase capacity beyond the cord rating.

Replaces worn twist-lock inlets on industrial gear

This socket serves as a direct field replacement for damaged or aged NEMA L7-30R inlets on generators, distribution boxes or temporary-power panels. The upgrade is worthwhile when the original housing is cracked, contacts are pitted or the locking cam no longer holds securely. It is not suited for applications requiring a different voltage, amperage or blade configuration.

Questions about this item

Will this L7-30R socket accept the 10 AWG cable I already use with my generator?

Yes, it is rated for 30 A at 277 V with 10 AWG cord and also supports 11 AWG and 12 AWG at 25 A.

How can I verify the socket is wired correctly after installation?

The terminals are marked X, Y, Z for line, W for grounded and G for grounding; a twist-lock engagement with an L7-30P plug confirms mechanical lock.

Does the package include a mating L7-30P plug or must I buy it separately?

Only the female socket is supplied; a compatible NEMA L7-30P plug must be purchased separately.
