FAQs
The 3333RW supports #14-8 AWG conductors using back wiring. Torque requirements are 14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG to ensure reliable conductivity. This configuration enables straightforward panel wiring, reduces terminal stress, and improves field reliability in tight electrical boxes.
The 3333RW is cULus Listed and carries IP66 protection with NEMA ratings including 3R, 4, 4X, and 12. These specifications confirm suitability for outdoor, washdown, and corrosive environments, helping ensure regulatory compliance and long-term performance in harsh industrial settings.
This receptacle is ideal for industrial control panels, rugged machinery, outdoor enclosures, and washdown zones. Its 30A, 125/250V, three-pole non-grounding configuration supports common industrial loads, while its watertight design protects against moisture and dust ingress, enabling reliable operation in manufacturing, packaging, and food-processing facilities.
The locking mechanism prevents accidental disconnection in vibration-heavy environments, maintaining consistent power delivery to critical equipment. Combined with IP66/NEMA 4X protection and a durable thermoplastic housing, the design reduces maintenance calls and aligns with stringent industry standards for safety and uptime.
Use back wiring with the specified #14-8 AWG conductors and apply the correct torque per conductor size to maintain solid contacts. Opt for the yellow, rugged housing material and ensure enclosure seals are intact to preserve IP66 ratings. Regular inspection of the nickel-plated bronze contacts helps prevent corrosion and sustain long-term reliability.
