Hubbell HBL2510 Locking Receptacle

The Hubbell HBL2510 is a 20 A L21-20R locking receptacle built for secure power connections in demanding environments. It suits electricians and facility managers who need reliable three-phase, four-wire grounding devices for industrial or commercial installations.

Capacity and headroom

Rated at 20 amperes, the receptacle handles standard 20 A circuit loads with a wire restraint recess that supports both back and side wiring to reduce terminal loosening. It is not designed for currents above the 20 A rating or for non-locking plug configurations.

Questions about this item

Does the L21-20R receptacle accept the same 20 A locking plugs I already use?

The HBL2510 is an L21-20R locking receptacle rated at 20 A, so it mates with standard 20 A locking plugs of the same configuration.

How can I confirm the receptacle is wired correctly after installation?

The face carries voltage colour coding that helps you verify the proper mating and wiring once the device is mounted.

What hardware comes with the HBL2510 and what must I source separately?

The receptacle includes an all-brass mounting and grounding system; mounting screws and wire connectors are not included and must be purchased separately.
