SKU CH-5JS9-H77ZG

A locking female connector rated 30 A at 277 V, ETL listed and compatible with 10–12 AWG cord

  • ETL listed for verified safety compliance
  • Twist-lock design prevents accidental disconnection
  • Rated 30 A at 277 V for industrial power
  • Accepts 10–12 AWG cords for flexible wiring
  • Clear X, Y, Z, G, W terminal markings simplify installation

Industrial locking connector

The LORDWORLD NEMA L7-30R is a twist-lock female socket rated for 30 amps at 277 volts AC. It carries an ETL listing that confirms compliance with UL 498 and CSA C22.2#42 standards. The connector is built for industrial generator and power-distribution use.

Wiring and cable compatibility

Terminals are marked X, Y, Z for line conductors, W for the grounded conductor and G for grounding. The device accepts 12 AWG through 10 AWG three-conductor cords across a wide range of jacket types including SJT, ST and SJO families. A rotated T-shaped blade prevents accidental mating with non-L7-30P plugs.

Suited for high-voltage locking applications

This part fits installers who need a 277 V locking receptacle for generator hook-ups or panel rewiring. It is not for buyers who need a straight-blade connector, a lower voltage rating, a male plug, or a device rated above 30 amps.

Questions about this item

What is the maximum continuous current this NEMA L7-30R socket can carry before the conductor becomes the limiting factor?

The connector is rated for 30 A at 277 V with 10 AWG cord and 25 A at 277 V with 12 or 11 AWG cord, so the cord gauge sets the sustained-current limit.

How much heat can build up inside the housing when the plug runs at full load all day?

The ETL-listed device meets UL 498 and CSA C22.2 No. 42 temperature-rise requirements, so heat stays within the limits those standards define for a 30 A 277 V locking socket.

Which cord gauges and jacket types must I already have to wire this connector?

It accepts 12 AWG, 11 AWG or 10 AWG three-conductor cords in SJT, SJTW, SJTR, SJTW-R, SJTO, SJTOW, SJTOOW, ST, STW, STOW, STOOW, SJE, SJEW, SJEO, SJEOW, SJEOOW, SJ, SHJ, SJO, SJOO, SJOW or SJOOW jackets.
