LORDWORLD NEMA L7-30P Locking Plug

This ETL-listed NEMA L7-30P locking plug provides a 30-amp, 277-volt male connection for industrial generators and equipment. The twist-lock design with a rotated T-shaped blade prevents accidental mating with incompatible receptacles. Terminals are clearly marked X, Y, Z, W and G for straightforward wiring. It accepts 10 to 12 AWG cord in a range of jacket types.

Suited for industrial rewiring

Electricians and maintenance teams replacing worn generator plugs or building custom 277-volt power cords will find the locking action secure and the terminal markings clear. Users needing a straight-blade plug, a lower-voltage locking type, or a connector rated above 30 amps should select a different device.

30A 277V NEMA L7-30P rating

The single specification that determines fit is the NEMA L7-30P configuration rated for 30 amps at 277 volts AC. Only receptacles carrying the matching NEMA L7-30R designation will accept this plug safely.

Questions about this item

When will the plug itself need replacement under normal use?

The ETL-listed L7-30P body is rated for 30 A at 277 V and built with heavy-duty conducting materials; it has no moving parts and no user-serviceable wear items, so the plug only needs replacement if the housing cracks or the terminals corrode.

What limits continuous current before the connector overheats?

The connector is rated 30 A with 10 AWG cord and 25 A with 12/11 AWG cord at 277 V; exceeding those ampacities for the wire size used will cause the terminal block to reach its thermal limit first.

Does the plug generate noticeable heat or noise when powering equipment all day?

As a passive twist-lock male connector it produces no noise; temperature rise stays within UL 498 and CSA C22.2 No. 42 limits provided the installed cord matches the 10 AWG/30 A or 12/11 AWG/25 A ratings.
