Overview

Plugrand delivers a compact, weather-ready locking adapter designed for 250V circuits in outdoor or semi-exposed environments. The 1-foot cord links a NEMA L14-30P locking male to a NEMA 6-20R female, offering a stable, twist-to-lock connection that helps minimize accidental disconnections. This 4-prong assembly is rated for up to 30A and around 250V, aligning with common generator setups and power tools. Built with an STW outdoor jacket and 10 AWG copper conductors, the design emphasizes durability while remaining easy to position in tight spaces.

Whether you are provisioning temporary power for a worksite, an outdoor event, or a backup power scenario, this adapter provides a practical bridge between compatible sources and devices. The compact length keeps clutter down and makes routing simpler, even when space is limited.
