Hubbell HBL5552B single receptacle

The Hubbell HBL5552B is a 20 A, 250 V AC single receptacle built for flush mounting in industrial or commercial wiring. Its black thermoplastic housing and straight blade orientation suit straight-in cord connections. The device meets CSA C22.2 No. 42, NEMA WD-6 and UL 498 standards for safety and performance. It provides a grounded, polarized connection for single-phase equipment.

Suited for 20 A 250 V straight-blade loads

This receptacle fits applications that require a NEMA 2-20R configuration with screw-terminal wiring. It is not designed for GFCI protection, so circuits needing ground-fault interruption must use a different device. Builders who need a covered outlet or a higher amperage rating should look at other models. The single-gang format limits use to one receptacle per opening.

Deciding spec: NEMA 2-20R configuration

The NEMA 2-20R configuration is the single specification that determines whether this receptacle matches the plug on your equipment. It defines the blade spacing and polarity for a 20 A, 250 V, two-pole, two-wire grounded connection. Verify the plug on your device carries the same 2-20P designation before purchasing. A mismatched configuration will prevent a safe and code-compliant installation.
