FAQs
The L2220RW supports back-wiring termination for #14-8 AWG conductors, enabling quicker, cleaner terminations with fewer field splice points. Ensure the conductors are prepared to the required gauge, strip to the proper length, and insert fully into the back-wiring terminals until secured. Verify a tight, vibration-free connection and test continuity after installation to prevent loose wires and arcing in 20A, 277/480V circuits.
This receptacle is rated for 20A at 277/480V (3ØY) with four poles and five wires. It features IP66, NEMA 4X, NEMA 3R, NEMA 4, NEMA 12 protections for a broad range of environments. Operating temperature is -40 to 75 °C, and the device is RoHS compliant and NOM cULus Listed, ensuring safe operation across outdoor, washdown, and industrial settings.
Yes. The L2220RW is designed for outdoor and washdown environments thanks to IP66 and NEMA 4X protections, plus NEMA 3R and 12 capabilities. Its yellow, high-visibility housing and locking mechanism provide secure, moisture-resistant connections ideal for industrial machinery, outdoor equipment, and processing lines subject to dust, water spray, and temperature fluctuations.
The L2220RW is RoHS Compliant and NOM cULus Listed, meeting European and North American safety and environmental standards. This reduces regulatory risk, simplifies global procurement, and ensures that the device can be used in regulated industries such as food processing, pharmaceuticals, and heavy manufacturing without requiring additional compliance steps.
The combination of corrosion-resistant nickel-plated bronze contacts, rugged glass-filled nylon housing, and watertight sealing reduces maintenance frequency and wear-related downtime. The back-wiring design speeds installation, lowering labor costs, while reliable locking ensures fewer connection failures under vibration or impact, contributing to lower total cost of ownership over the device lifecycle.
