Hubbell HBL2420 Locking Receptacle

The Hubbell HBL2420 is a 20 A, 250 V locking receptacle designed for secure power connections in professional audio and video environments. It suits installers and technicians who require a reliable NEMA L15-20R interface for equipment racks or distribution boxes. The black, all-brass construction provides corrosion resistance and a low-resistance ground path for critical infrastructure.

Wire restraint recess eases installation

A wire restraint recess accommodates both back and side wiring, reducing the chance of terminal connections loosening over time. Face colour coding by voltage helps technicians quickly identify and mate the correct devices during setup or maintenance. The all-brass mounting system eliminates the need for separate steel grounding hardware, simplifying the build.

Brass components withstand sustained use

The all-brass mounting and grounding system maintains a stable ground path and resists corrosion during continuous operation. The locking mechanism holds the plug firmly under vibration or cable strain, preventing intermittent contact during long production runs. The wire restraint design keeps conductors secure without periodic re-tightening.

Questions about this item

What is the maximum continuous current the L15-20R receptacle can handle before the wire restraint recess becomes critical?

The receptacle is rated for 20 A continuous current. The wire restraint recess on both back and side wiring terminals reduces the chance of loosening under sustained load.

Does the all-brass mounting and grounding system run cooler than steel when the device carries 20 A all day?

Brass provides a lower-resistance ground path and better corrosion resistance than steel, which helps maintain stable temperatures during extended operation at the rated 20 A.

What voltage-rated plug must I already own to mate with this L15-20R receptacle?

You need a locking plug rated for 250 V that matches the L15-20R configuration. The face colour coding identifies the voltage rating for correct mating.
