Industrial Locking Receptacle

The Hubbell HBL2720SR2 is a three-pole, four-wire locking receptacle rated for 30 A at 250 V AC. It uses a NEMA L15-30R configuration with a twist-lock mechanism and visual alignment indicators. The housing is made from impact-modified Valox and PBT materials in a gray finish for corrosion and impact resistance.

Suited For Industrial Power Connections

This device suits installers who need a flush-mount receptacle with screw terminals accepting 8 AWG to 16 AWG conductors. It is not for buyers who require a different NEMA configuration, a higher amperage rating, or a receptacle rated for wet or outdoor locations.

NEMA L15-30R Configuration Decides Fit

The single specification that determines compatibility is the NEMA L15-30R rating, which defines the three-pole, four-wire layout at 30 A and 250 V AC. Match this exactly to your plug and circuit requirements before purchase.

Questions about this item

How much heat does the HBL2720SR2 dissipate when running at 30 A continuously?

The receptacle is rated for maximum continuous operation at 75°C (167°F) and its Valox housing resists corrosion and impact in dry indoor locations.

What wiring must I already have to install this L15-30R receptacle?

You need a three-pole, four-wire supply rated for 30 A at 250V AC and screw terminals accept conductors from 8 AWG to 16 AWG.

Will this twist-lock receptacle mate with older NEMA L15-30 plugs I already own?

Yes, the NEMA L15-30R configuration follows the standard three-pole, four-wire layout, so compatible locking plugs will engage and lock correctly.
