HBL2440 Locking Receptacle 20 A

The Hubbell HBL2440 is a locking receptacle rated for 20 A at 18 V. It suits installers who need a secure power connection for audio and video equipment. The twist-lock design prevents accidental disconnection during use.

Sustained connection integrity

A wire restraint recess supports both back and side wiring to reduce the chance of terminal loosening over time. An all-brass mounting and grounding system offers a lower resistance ground path than steel alternatives. Brass construction also provides greater resistance to corrosion under continuous operation.

L18-20R interface limits

The L18-20R configuration mates only with matching plugs of the same voltage and amperage rating. Face colour coding by voltage helps installers identify the correct device quickly. This receptacle does not accept straight-blade or other locking blade patterns.

Questions about this item

How much heat does the HBL2440 locking receptacle generate when running at 20 A all day?

The receptacle is a passive wiring device with no active electronics, so it produces no measurable heat of its own; any warmth comes only from the current flowing through the conductors.

What wiring must already be in place for the L18-20R receptacle to work?

You need a three-phase circuit providing 18 A or 20 A service with conductors sized for the load, plus a compatible L18-20P plug on the equipment side.

Will the HBL2440 mate with older L18-20 plugs already installed in my facility?

Yes, the face colour coding follows the NEMA L18-20 standard, so any existing L18-20P plug will lock securely into this receptacle.
