Thomas Betts E989NNJ Junction Box Pvc Nema 4 4X 6P

Product Description

The THOMAS BETTS E989NNJ is a polyvinylchloride (PVC) junction box electrical enclosure rated NEMA 4, 4X, and 6P. It is designed to house and protect electrical connections in environments where moisture, corrosion, and dust are ongoing concerns. The enclosure measures 4 inches wide, 4 inches high, and 2 inches deep and ships at 6.8 pounds. A screw flat cover with a foam-in-place gasket provides a reliable environmental seal, and stainless steel screws are included. Electricians and industrial maintenance technicians install this type of enclosure in both commercial and light industrial applications where a watertight, corrosion-resistant housing is required by code or project specification.

This enclosure is suited for indoor and outdoor electrical installations where exposure to water, chemicals, or corrosive atmospheres is a factor. Typical use cases include control wiring terminations, sensor connections, and field-wiring junction points in wash-down areas, marine environments, chemical processing facilities, and outdoor electrical panels. The PVC construction resists rust and degradation that would affect metal enclosures in similar service conditions.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Disconnect and lock out all power circuits before opening or wiring inside the enclosure. Ensure all conduit entries are properly sealed with rated fittings to maintain the NEMA environmental rating after installation. Do not exceed the enclosure volume fill limitations defined by NEC Article 314 for junction boxes.
