Locking Receptacle L7-20R for 20 A 277 V circuits

The Hubbell HBL2330 is a straight-blade locking receptacle rated 20 A at 277 V AC. It accepts a matching L7-20P plug and provides a secure, polarised connection for single-phase loads. The nylon housing carries a NEMA 1 enclosure rating and is finished in black. Two poles and three screw-terminal wires complete the standard wiring style.

Flush-mount single-gang design with screw terminals

The device installs in a single-gang opening using a flush-mount profile that requires no flange. Brass contacts and screw terminals accept standard conductors without special tools. Because the receptacle is non-flanged and ships without a cover, the installer supplies a compatible wall plate and ensures the box depth suits the flush profile. No AFCI function is integrated.

Brass contacts maintain integrity under continuous

Under sustained 20 A current the brass contact surfaces resist heating and preserve clamping force on the screw terminals. The nylon housing remains dimensionally stable at 277 V AC single-phase operation. The locking action prevents accidental disconnection during vibration or cable movement. No shrouding is present, so the installer must verify clearances in the enclosure.
