Watertight Straight Blade Plug 5-20P

This HUBBELL WIRING DEVICE-KELLEMS plug provides a grounded 20 A, 125 V AC connection with an IP69K rating. It suits industrial environments where equipment faces high-pressure washdown, corrosion or heavy moisture. The yellow housing and screw-terminal wiring accept cables from 0.375 in to 0.625 in diameter.

NEMA 5-20P configuration for industrial power

The straight-blade, three-blade design fits standard 5-20R receptacles and supports single-phase loads up to 1 hp. Screw terminals secure conductors without special tooling, freeing installers from crimping equipment. Polarised blades prevent reverse wiring, while the corrosion-resistant housing protects contacts in damp or chemical atmospheres.

IP69K sealing under sustained wet conditions

The plug maintains its watertight seal during prolonged high-temperature, high-pressure cleaning cycles typical of food-processing or heavy-equipment wash bays. Corrosion-resistant materials retain integrity where standard plugs degrade, reducing nuisance trips on downstream circuit breakers. Industrial-grade construction withstands repeated mating cycles without loss of ingress protection.
