Industrial 30A 277V Locking Plug

The LORDWORLD NEMA L7-30P is a straight-blade male connector rated for 30 amps at 277 volts. It suits generator leads, heavy-duty extension cords and industrial equipment that require a twist-lock connection. The ETL listing confirms compliance with UL 498 and CSA C22.2 No. 42 standards.

Sustained Load Performance

The plug carries the full 30 A at 277 V when paired with 10 AWG conductors and 25 A with 12 or 11 AWG. Heavy-duty conducting materials and clearly marked X, Y, Z line terminals plus G and W grounding terminals support reliable termination for continuous operation. The twist-lock action resists vibration-induced disconnection.

Build and Connector Practicality

Yellow thermoplastic housing provides visible identification in dim environments. The rotated T-shaped blade prevents accidental mating with non-L7-30R receptacles. DIY rewireable design accepts a wide range of 3-conductor cords from 12 to 10 AWG including SJT, ST, STOOW and SJEOOW types. Turn-and-pull locking ensures secure engagement day to day.

Questions about this item

Does the NEMA L7-30P plug generate noticeable heat when powering a 30 A 277 V load continuously?

The ETL-listed plug uses heavy-duty conducting materials rated for 30 A at 277 V with 10 AWG cord, so it runs within its thermal design during continuous operation.

What cable size and type must I already have to wire this L7-30P connector?

You need a 3-conductor cord between 12 AWG and 10 AWG such as SJT, SJTW, ST, STW, SJO, SJOW or equivalent types listed in the compatibility table.

Will this yellow L7-30P mate safely with the older L7-30R receptacles already installed in my facility?

Yes, the rotated T-shaped blade keying prevents accidental cross-connection while ensuring correct engagement with any standard NEMA L7-30R socket.
