Hubbell HBL4700 Locking Receptacle

The Hubbell HBL4700 is a 15A duplex locking receptacle with NEMA L5-15R configuration designed for single-phase 125V AC systems. Its twist-lock design secures plug retention in industrial indoor environments where vibration or movement could disconnect standard outlets. Reinforced thermoplastic construction with nylon housing provides impact resistance for demanding dry locations. This flush-mount unit includes mounting hardware and a cover for immediate installation.

Verify Circuit And Wiring Compatibility

Confirm your circuit supplies 125V AC single-phase power with a 15 amp rating matching the L5-15R specification. The screw terminals accept wire sizes from 18 AWG to 10 AWG with 14 AWG recommended for optimal connection. Ensure the electrical box accommodates a flush-mount, non-flanged device with the included mounting strap. This receptacle is not suited for wet locations or outdoor exposure without additional weatherproof enclosures.

Sustained Load Thermal Performance

The receptacle carries a maximum continuous operating temperature of 75°C (167°F) without impact, with a full range from -40°F to 167°F. Single-piece all-brass contacts maintain consistent conductivity during extended 15 amp loads without the degradation seen in multi-piece contact designs. Reinforced thermoplastic base resists thermal cycling stress in industrial settings where equipment runs continuously. The twist-lock mechanism prevents resistance buildup from loose connections under prolonged vibration.

Questions about this item

Does the Hubbell HBL4700 duplex locking receptacle ship with mounting hardware and a cover, or must they be ordered separately?

The unit includes a mounting strap and hardware plus a cover, so no extra parts are needed for a standard flush-mount installation.

Should I select the L5-15R version rated at 15 A and 125 V, or is another NEMA configuration offered for this model?

This model is offered only in the L5-15R configuration rated 15 A, 125 V AC for single-phase, 2-pole, 3-wire service.

What does the 15 A rating mean when the receptacle is installed in a real circuit with 10 AWG to 18 AWG conductors?

The screw terminals accept 18 AWG to 10 AWG wire with 14 AWG recommended, allowing the receptacle to carry its full 15 A rating within the -40 °F to 167 °F operating range.
