Industrial Watertight Connector L6-20R

The Hubbell HBL27W48 is a 20 A, 250 V AC locking connector built for industrial and commercial sites that demand reliable watertight power connections. Its NEMA L6-20R configuration suits single-phase equipment in washdown zones, food-processing areas and outdoor generator hook-ups.

Thermoplastic Elastomer Body and Screw Terminals

A smooth thermoplastic elastomer shell removes crevices where debris or moisture can collect, making high-pressure washdowns faster and more effective. Nickel-plated brass contacts and a clear polycarbonate retainer resist corrosion and UV exposure, while screw terminals accept wire sizes from 16/3 SJ up to 10/5 S for secure field wiring.

Cord Diameter and Temperature Limits

The connector only accepts cables between .375 and .875 inches in diameter, so installers must verify cord size before specifying it. Continuous operation is rated from -40 °C to +60 °C, and the IP69K and NEMA 4, 4X, 6, 6P ratings guarantee sealing against high-pressure jets and temporary immersion, but not against continuous submersion beyond the tested depths.

Questions about this item

What does the L6-20R NEMA configuration support in practice?

The L6-20R configuration provides a 20 A, 250 V AC single-phase locking connection with straight orientation for secure mating.

What cable diameters and wire sizes does the connector accept?

It accommodates cords from .375 in to .875 in diameter and wire sizes from 16/3 SJ minimum up to 10/5 S maximum.

How is the connector wired and what step is often missed?

Wires are terminated under screw terminals; the step often missed is torquing each terminal to the specified value so the connection remains watertight.
