Feature → Business Impact → Application: Watertight locking receptacle design prevents moisture and dust ingress, reducing corrosion and contact resistance, which translates to fewer nuisance outages and extended service life for industrial equipment in wet locations. Application: Outdoor power distribution, hazardous-area facilities, and maintenance yards where exposure to rain and spray is common. Feature → Business Impact → Application: Glass-filled nylon face/body with thermoplastic construction delivers high impact resistance and chemical compatibility, lowering replacement costs in tough environments. Application: Heavy-duty industrial facilities, manufacturing floors, and outdoor panels exposed to weather. Feature → Business Impact → Application: Nickel-plated bronze contacts provide reliable, low-resistance connections even after repeated mating cycles, improving push-in reliability and reducing contact wear. Application: Lifting stations, motors, and pumps that undergo frequent cycling. Feature → Business Impact → Application: Back wiring with a 6.75 in length, 4 in height, and 4.25 in width creates a compact, versatile footprint that simplifies panel layouts and allows easier retrofits. Application: Renovations and new builds where space is at a premium. Feature → Business Impact → Application: Locking receptacle with 20A rating at 277V (L7-20 configuration) supports secure, code-compliant connections for single-phase, three-wire systems, reducing accidental unplugging and improving operator safety. Application: Outdoor feeders, stage lighting, and industrial equipment hookups in wet environments. Feature → Business Impact → Application: RoHS compliance and cULus listing ensure regulatory alignment and safer supply chains, minimizing compliance risk and enhancing procurement confidence. Application: Any facility requiring formal certification trails for electrical components in North America.

FAQs
The L720RW supports back wiring with allowable wire sizes of #14-8 AWG. Its back-wiring method and 6.75 in length by 4 in height enclosure design simplify panel layout and wiring access, making it well-suited for new installations or retrofits in industrial environments with limited space.
The L720RW is IP66 and NEMA 4X rated, offering robust protection against dust and water intrusion in harsh environments. It is RoHS compliant and cULus listed, ensuring regulatory compliance and safety for North American installations, which reduces risk during audits and improves procurement confidence.
Best suited for outdoor and wet-location power connections, the L720RW supports L7-20 277V configurations for two-pole, three-wire systems. It is ideal for outdoor equipment hookups, maintenance yards, and industrial machinery that requires secure, watertight power connections while enduring humidity and washdowns.
The locking receptacle secures the plug-in connection, preventing accidental disconnection in environments with vibration or movement. This reduces arcing risk and downtime, improves operator safety, and ensures a stable power supply for critical equipment such as pumps, motors, and outdoor lighting.
With corrosion-resistant nickel-plated bronze contacts and a durable thermoplastic body, the L720RW offers extended service life in tough environments. The watertight seal minimizes ingress-related wear, reducing maintenance frequency and replacement costs, while RoHS and cULus certifications support long-term compliance and supplier reliability.
