Watertight Twist-Lock Receptacle 20 A

The Hubbell HBL2410SW is a 20 A watertight twist-lock receptacle rated for 125/250 V AC single-phase power. It uses a NEMA L14-20R configuration with three poles and four wires. The device suits industrial or outdoor installations that require a secure locking connection. Its gray Valox housing meets NEMA 4, 4X and 12 enclosure ratings.

Thermals Noise Power Draw

As a passive wiring device the receptacle generates no audible noise and draws no power of its own. Brass screw terminals provide a reliable electrical path under normal load up to the 20 A rating. The Valox housing resists heat distortion within the specified voltage range. No active cooling or thermal management is required.

Build Quality Connectors Mounting

The unit features a reinforced nylon locking flip-up cover that shields the contacts when not in use. A safety shroud surrounds the blades to reduce accidental contact. Flush mounting with a single-gang footprint simplifies panel installation. Screw-terminal wiring accepts standard conductors for straightforward termination. The assembly weighs 0.55 lb and measures 4.000 inches in length.

Questions about this item

How is the HBL2410SW flush-mounted and which step is often missed?

Mount the gray Valox housing flush to the panel using the four screw holes, then torque the brass screw terminals to spec; the step often missed is securing the locking flip-up cover latch so the NEMA 4X seal stays intact.

What maintenance or replacement will the HBL2410SW need over time?

Inspect the brass contacts and Valox shroud for corrosion or cracking; replace the receptacle if the flip-up cover spring weakens or the NEMA 4X gasket shows compression set that lets moisture past the seal.

What limit appears first on the HBL2410SW during sustained 20 A loads?

The 20 A screw-terminal rating is the first limit; continuous operation at full current will heat the brass contacts and Valox housing until the 125/250 V AC thermal threshold is reached.
