FAQs
Install the 65W34BK using the back-wiring method with #18-10 AWG conductors as specified. Maintain the 15A rating at 277V and secure conductors under the terminal clamps to the nickel-plated bronze contacts. Torque should be matched to the wire size (14–16 lbf-in for #10-14 AWG; 20 lbf-in for #8 AWG) to ensure a reliable, long-term connection and minimize looseness from vibration.
The L7-15 locking configuration is a two-pole, grounding arrangement designed for 277V systems. Its locking design resists accidental disconnections in vibration-heavy environments such as conveyors and outdoor equipment. This leads to safer operation, fewer unexpected outages, and consistent power delivery for critical industrial machinery and control circuits.
Yes. The 65W34BK features IP66 environmental resistance along with compatible NEMA ratings (3, 4, 4X, 12, 3R). This combination safeguards against dust, water ingress, and washdown exposure, making it appropriate for outdoor enclosures, wet facilities, and harsh manufacturing environments where reliability and compliance are essential.
The receptacle is cULus Listed, with IP66 and multiple NEMA ratings (3, 4, 4X, 12). These certifications validate safety, performance, and suitability for industrial environments. Compliance reduces risk during audits, supports hazardous-area installations where required, and ensures standardized cross-site compatibility for maintenance and procurement teams.
Investing in the 65W34BK reduces downtime due to secure connections and robust sealing. The back-wiring capability speeds field terminations, while the locking design minimizes accidental disconnections in vibration-prone equipment. Over time, this lowers maintenance labor, extends component life in washdown zones, and improves overall equipment availability and plant productivity.
