Industrial 20 A 480 V Twist-Lock Receptacle

The Hubbell HBL2430 is a NEMA L16-20R locking receptacle rated for 20 amps and 480 V AC three-phase power. It is built for industrial environments that require a secure, twist-lock connection in dry, indoor locations. The device accepts #16 to #8 AWG solid or stranded copper wire via back or side screw terminals. UL 498 listed and CSA C22.2 No. 42 certified.

Sustained three-phase load performance

The receptacle carries its full 20 A rating continuously across an operating range of -40 °F to 167 °F (-40 °C to +75 °C). Brass contacts and an all-brass grounding system resist corrosion during extended duty cycles. A wire-restraint recess at each terminal reduces loosening under vibration or thermal cycling. Nylon housing maintains structural integrity at the upper temperature limit.

Thermal and installation characteristics

The nylon housing and brass components operate without active cooling in normal indoor service. Face colour coding by voltage helps prevent mating errors during installation or maintenance. Flush-mount design includes mounting hardware for standard electrical boxes. Screw terminals accept only copper wire in the specified gauge range for reliable termination.
