Hubbell HBL2410SR Locking Receptacle
The Hubbell HBL2410SR is a NEMA L14-20R locking receptacle rated for 20 A at 125/250V AC. It uses a twist-lock mechanism with a 3-pole, 4-wire grounded design for secure connections in industrial environments. The housing is engineered thermoplastic (Valox) with nylon components described as corrosion- and impact-resistant. It carries a NEMA Type 1 enclosure rating and IP20 rating for indoor use only.
Capacity and headroom
The receptacle accepts #16 AWG to #8 AWG solid or stranded copper wire via screw terminals marked to UL498. It operates continuously from -40°F to 167°F (-40°C to +75°C) and meets UL94 V2 flammability standards. The non-flanged, surface-mount design fits standard industrial boxes but offers no weather sealing beyond the IP20 indoor rating. Brass contacts and a .031" brass spring maintain connection integrity under vibration.
Bundled accessories and software
The product ships as the receptacle unit only with no additional accessories, software, or wiring hardware included. Installation requires a compatible enclosure, mounting screws, and appropriate gauge wire supplied by the installer. Color-coded voltage rating remains visible during operation for quick identification. Polarized configuration ensures correct mating with L14-20P plugs only.

Questions about this item
Will the 20 A 125/250 V rating on this L14-20R receptacle match the generator inlet I already have?
Yes — the NEMA L14-20R configuration is a 3-pole, 4-wire grounded design rated for 20 A at 125/250 V AC single-phase, so it matches any L14-20P plug or inlet with the same rating.
How can I verify the receptacle is wired correctly after installation?
Terminals are marked X, Y, Z, White and Green per UL498; with power off, confirm each conductor lands on its marked terminal, then energise and measure 125 V between each hot (X, Y) and neutral (White) and 250 V between the two hots.
Does the box include mounting hardware or a cover plate, or must I buy them separately?
The receptacle ships with its engineered thermoplastic Valox housing, brass contacts and .031" brass spring; mounting screws and a weatherproof cover plate are not included and must be purchased separately.
