Hubbell HBL2630 NEMA L7-30R Twist-Lock Receptacle

The Hubbell HBL2630 is a NEMA L7-30R twist-lock receptacle rated for 277V and 30A, engineered to deliver a secure twist-to-lock connection with 3-wire grounding that carries two hot conductors plus a dedicated equipment ground for safe, reliable operation on demanding circuits. Its locking interface resists accidental disconnection in environments subject to vibration, impacts, or frequent movement, making it a practical choice for commercial lighting feeds, event or stage lighting setups, and other industrial applications where a stable, difficult-to-disconnect power connection is essential, including production facilities, warehouses, and loading docks. As a Hubbell-manufactured L7-30R receptacle, the HBL2630 is designed specifically for 277V, 30A, three-wire grounding configurations, aligning with typical 277V power distributions found in commercial buildings and professional lighting systems that require a durable, lockable receptacle interface for long-term reliability in 277V distribution networks.
