IP67 waterproof rating and locking mechanism ensure a secure interface in harsh conditions. The L720PW supports two poles, three wires, and a 20 A, 277 V configuration (L7-20), delivering robust power delivery for motors and machinery. This combination minimizes miswiring and accidental disconnections, improving uptime in outdoor, wet, or dusty environments. Back wiring for #18-10 AWG conductors and a cord diameter range of 0.36-0.84 in provides installation flexibility and a solid, maintainable connection, reducing field labor time and rework. The nickel-plated brass contacts, Santoprene seals, and a tough nylon body deliver chemical resistance, corrosion protection, and long service life in demanding industrial settings, cutting replacement costs and downtime. The broad environmental compatibility, including IP67 and NEMA ratings, enables design-in for washdown areas, outdoor equipment, and rugged control panels, streamlining procurement and compliance. RoHS compliance and cULus listing support safety and regulatory requirements, reducing risk during audits and customer inspections. Weight at 1.025 lb and compact dimensions simplify enclosure planning and field retrofits, helping engineers meet tight installation schedules without sacrificing reliability.

FAQs
The L720PW uses back wiring for #18-10 AWG conductors and requires a torque of 14-16 lbf-in to secure contacts. Plan for a 4.75 inch length, 3.75 inch width, and 3.75 inch height enclosure footprint to fit standard L7-20 inlets. Ensure mating connectors are IP67-rated and mounted in a weatherproof enclosure suitable for outdoor or washdown areas.
Key specs include a 20 A amperage rating, 277 V voltage rating, NEMA L7-20 configuration, two poles with three wires, back wiring method, and IP67 protection. The contacts are nickel-plated brass, and the body is nylon with Santoprene seals, designed for rugged industrial use and reliable mating with compatible locking receptacles.
Yes. The L720PW is designed for harsh environments with an IP67 rating and compatibility with NEMA 4, 4X, 6, and 6P protections. This makes it ideal for outdoor installations, washdown areas, and machinery exposed to moisture, dust, or corrosive cleaning processes while maintaining electrical integrity.
The L720PW is RoHS compliant and cULus Listed, ensuring compliance with restricted substances and safety standards for electrical products in North America. These certifications simplify auditing, support supplier qualification, and help meet customer and regulatory requirements in industrial projects.
The locking design and watertight seal reduce connection loosening and ingress, lowering downtime and maintenance frequency. Durable materials and back-wiring compatibility streamline field service, shorten installation times, and extend service intervals, contributing to a lower total cost of ownership in facilities with outdoor or wet-location equipment.
