30 A Twist-Lock Receptacle
The Hubbell HBL2710SR is a 30 A locking receptacle rated for 125/250 V AC single-phase supply. It uses a NEMA L14-30R configuration with three poles and four wires in a straight orientation. The gray Valox housing is shrouded for safety and mounts on a surface without a flange. Screw terminals accept standard wiring for a secure connection.
Suited for high-current equipment needing
Installers wiring generators, welders or temporary power distribution will appreciate the twist-lock design that resists accidental disconnection. The single-gang, non-flanged body fits surface-mounted boxes where a flush flange is not required. Buyers who need a flanged inlet, a different NEMA rating or a cover included should look at other configurations.
Surface-mount box and L14-30P plug complete
The receptacle mounts directly to a compatible surface box and pairs with an L14-30P plug on the equipment cord. Brass contacts and screw terminals handle up to 30 A without additional hardware. The NEMA 1 enclosure rating means the device is intended for indoor use where a sealed rating is not required.

Questions about this item
Do I need a 30 A double-pole breaker and 125/250 V AC supply already installed for this L14-30R receptacle?
Yes, the receptacle is rated for 30 A at 125/250 V AC single-phase and requires a matching circuit breaker and supply wiring to operate safely.
Will my existing 4-wire cord with an L14-30 plug mate correctly with this 3-pole, 4-wire twist-lock receptacle?
The NEMA L14-30R configuration accepts a standard L14-30 plug; the shrouded, polarized design ensures proper alignment with your current cord set.
How can I verify the receptacle is wired correctly after installation?
With power on, measure 125 V between each hot terminal and neutral, and 250 V between the two hot terminals; the grounding terminal should show continuity to the panel ground.
