Industrial Watertight Plug for 20 A Circuits

This Hubbell HBL15W33A straight-blade plug is rated for 20 A at 125 V AC and built to NEMA 5-20R configuration. The yellow thermoplastic elastomer and Valox housing resists moisture ingress in wet or outdoor locations. It accepts cord diameters from .300 to .625 inches and suits industrial-grade temporary power needs.

Sustained Load Behaviour on 20 A Service

The plug maintains secure contact under continuous 20 A draw without overheating the terminals. Its two-pole, three-wire design handles single-phase loads typical of construction lighting, pumps or portable heaters. The watertight seal remains effective during extended operation in rain or wash-down environments. No antimicrobial or corrosion-resistant coating is applied.

Thermal, Noise and Power Characteristics

As a passive connector it generates no noise and draws no power of its own. The Valox body stays cool to the touch at rated current because heat dissipates through the copper alloy blades. Yellow colour aids visual inspection for damage or contamination in low-light conditions. The device adds no measurable resistance to the circuit.

Questions about this item

Does the HBL15W33A plug run hot or draw extra power when used continuously at 20 A 125 V?

The plug is rated for 20 A at 125 V AC and uses thermoplastic elastomer and Valox materials designed for industrial duty; no additional heat or power specifications are published for continuous operation.

What cable diameter must I already have for the HBL15W33A to clamp correctly?

The cord grip accepts cables from .300 in to .625 in outer diameter, so your cable must fall within that range for a secure, watertight connection.

Will the HBL15W33A mate with an older 5-20R receptacle I already have installed?

Yes, the plug follows the NEMA 5-20R configuration with 2 poles and 3 wires, matching standard 20 A 125 V receptacles already in place.
