Hubbell HBL2730SW 30A 480V L16-30R Watertight Locking Receptacle

Product Description

The HUBBELL HBL2730SW is a single-configuration, watertight twist-lock receptacle rated for 30 amperes at 480 volts AC, 3-phase. It features an L16-30R configuration with 3 poles and 4 wires, including a grounding contact. The housing is constructed from Valox PBT reinforced thermoplastic polyester, engineered to handle heavy-duty industrial environments. The Safety-Shroud design provides a physical interlock that ensures devices are properly aligned and seated before power is transferred. Color-coded voltage markings remain visible even when the device is in use, supporting fast visual verification during service or inspection.

This receptacle is designed for industrial and commercial power distribution applications where watertight protection is required. Typical installations include manufacturing facilities, processing plants, outdoor power panels, and anywhere a NEMA 4, 4X, or 12 enclosure rating is specified. The IP66 ingress protection rating makes it suitable for washdown environments and exposed outdoor locations. It is installed by licensed electricians working on 3-phase distribution systems and power outlet stations requiring locking, weather-resistant connections.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out/tag out the circuit before wiring or replacing this receptacle.
