IP67-rated housing with Santoprene thermoplastic elastomer seals the conductors against water, dust, and contaminants. This rugged construction translates to lower maintenance costs and fewer unplanned outages. It is ideal for outdoor equipment, damp enclosures, and high-humidity production lines where ingress protection is non-negotiable. With a 20A, 125V rating and a two-pole, three-wire grounding configuration (5-20R), it accommodates common industrial loads while maintaining NEC-aligned safety. The design supports back-wire and screw terminations for secure, field-repairable connections, reducing rewiring time during panel upgrades. This compatibility accelerates installation in new builds and retrofit projects. Nickel-plated brass contacts deliver reliable, low-resistance connections with superior corrosion resistance, essential in moist environments. The straight blade design minimizes alignment issues during mating in tight spaces, while the Santoprene housing provides impact resistance. Cord range supports 0.30–0.65 in diameter conductors, enabling flexible harness integration in existing systems. Core-pack packaging aids stocking and field deployability, balancing performance, cost, and serviceability in industrial power distributions.

FAQs
Power must be off before installation. Prepare #18-10 AWG conductors and insert into the back-wire terminals, then secure with the provided screws. Ensure the nickel-plated brass contacts are fully seated and the Santoprene housing is closed to maintain IP67 protection. Verify the 14 in-lbf torque on the terminal screws and test continuity after installation to confirm a solid, watertight connection.
The 15W33BK is rated for 20A at 125V and uses a two-pole, three-wire grounding receptacle (5-20R). It supports #18-10 AWG conductors with back-wire termination and requires a minimum clearance for safe operation. It is suited for industrial loads in control panels and equipment enclosures, with a torque rating of 14 lbf-in to ensure consistent clamping force.
Yes. The connector is IP67 rated and designed for damp or wet locations, providing robust ingress protection. It is cULus Listed, aligning with common NEC safety standards, making it appropriate for outdoor equipment, damp control panels, and industrial installations where moisture resistance is critical.
The product carries cULus Listed certification, indicating conformance to safety standards for North American electrical equipment. This certification supports compliance with NEC requirements and reduces risk during audits. The IP67 environmental protection rating further ensures suitability for harsh, wash-down, or outdoor environments, improving reliability in challenging industrial settings.
The combination of IP67 protection, durable nickel-plated brass contacts, and Santoprene housing reduces corrosion and moisture-related failures, lowering maintenance time and unplanned downtime. Back-wire plus screw termination speeds field service, enabling quicker panel upgrades and lower labor costs. Overall, these features contribute to extended service intervals and a measurable return on investment in industrial power distribution.
