Industrial Locking Plug

The LORDWORLD NEMA L7-20P is a 20 amp, 277 volt male AC connector built for industrial generators and equipment. Its ETL listing confirms compliance with UL 498 and CSA C22.2 standards for safe installation. The twist-lock mechanism secures the connection against vibration or accidental disconnection. It suits electricians and technicians who need a dependable, rewireable cord end.

Cord Compatibility and Wiring

The plug accepts a wide range of three-conductor cords from 18 AWG up to 10 AWG, including SJT, ST, and SJO types. Ampacity varies with wire size: 20 amps on 12 or 10 AWG, 18 amps on 14 or 13 AWG, 13 amps on 16 or 15 AWG, and 10 amps on 17 or 18 AWG. Terminals are clearly marked X, Y, Z for lines, G for grounding, and W for the grounded conductor to simplify field wiring. Builders who need a plug for cable outside this AWG range or a different pin configuration cannot use this model.

Sustained Load Performance

Rated for 5540 watts at 20 amps and 277 volts, the connector uses heavy-duty conducting materials to handle continuous industrial current. The robust housing and locking action maintain contact integrity during extended generator runs. The rotated T-shaped blade prevents mating with incompatible receptacles, reducing the risk of cross-voltage connection. Installers who require a higher amperage rating or a non-locking straight blade should select a different device.

Questions about this item

At what sustained current does the 277 V rating reach its 5540 W limit?

The plug is rated 20 A at 277 V, giving a maximum of 5540 W when used with 12/10 AWG cord.

Does the connector run hot or draw extra power during continuous 20 A operation?

The ETL-listed design uses heavy-duty conducting materials rated for the full 20 A / 277 V load, so normal operation stays within the certified temperature rise.

What cord gauge and type must I already have to wire this L7-20P plug?

It accepts 18–10 AWG three-conductor cord such as SJT, SJTW, ST, STW, STOOW, SJE, SJEOOW, SJO, SJOW, SJOOW and similar types.
