Watertight Straight Blade Connector

The Hubbell HBL15W33 is a 20 A, 125 V AC connector rated for wet or damp locations. Its yellow thermoplastic elastomer housing and press-on cap seal against moisture while the screw terminals accept three wires from 0.3 to 0.66 in cable diameter. It suits contractors and facility managers who need a grounded NEMA 5-20R connection that stays reliable outdoors or in wash-down areas.

Sustained load behaviour

The device carries its full 20 A rating continuously without derating when installed within the specified cable range. Thermoplastic elastomer housing resists deformation and chemical attack during long shifts in humid or hosed-down environments. The screw-terminal grip remains secure through thermal cycling, and the watertight seal maintains integrity so leakage current stays negligible over extended duty cycles.

Pre-order checks

Verify that the supply circuit is single-phase 125 V AC protected by a 20 A breaker and wired with conductors sized for 20 A service. Confirm the cable outer diameter falls between 0.3 and 0.66 in so the gland compresses evenly. Ensure the mounting location allows straight orientation and that local code accepts a general-grade, 1 hp rated connector for the intended motor or heating load.

Questions about this item

How much heat or noise does the HBL15W33 produce when it runs continuously at 20 A?

The connector is a passive wiring device with no moving parts or electronics, so it generates no audible noise and negligible heat when used within its 20 A, 125 V rating.

What cable and tools do I need to terminate the HBL15W33 properly?

You need a 3-wire cable with an outside diameter between 0.3 in and 0.66 in, plus a screwdriver for the screw terminals; the press-on cap is included.

Can I plug the HBL15W33 into an older 15 A NEMA 5-15R receptacle?

No, the connector has a 5-20R blade configuration with a horizontal neutral slot that physically prevents insertion into a 15 A 5-15R outlet.
