Thomas Betts E987R Junction Box Nema 4 4X 6x6x4 in

Product Description

The THOMAS BETTS E987R is a thermoplastic junction box enclosure rated NEMA 4 and 4X, designed to house and protect electrical connections in environments where moisture, dust, and corrosion are concerns. The enclosure features a screw flat cover secured with stainless steel screws and includes a foam-in-place gasket for a reliable seal. Measuring 6 inches wide, 6 inches high, and 4 inches deep, it provides adequate interior volume for terminal blocks, wire splices, and low-voltage connections. Licensed electricians and industrial maintenance techs are the primary installers of this enclosure type.

This enclosure suits residential, commercial, and light industrial applications where a watertight and corrosion-resistant housing is required. It is appropriate for outdoor installations, wet locations, and areas with washdown exposure. The thermoplastic construction makes it a practical alternative to steel enclosures in corrosive environments such as chemical processing areas, food service facilities, and coastal installations where metal enclosures are prone to rust.

Compatibility

Designed as an OEM-style thermoplastic junction box for use in NEMA 4 and 4X rated electrical enclosure applications requiring a 6 inches x 6 inches x 4 inches form factor.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out all power to circuits entering the enclosure before beginning work. Ensure all conduit entries are properly sealed with rated fittings to maintain the NEMA 4 4X integrity of the enclosure. Do not overtighten the cover screws, as thermoplastic enclosures can crack if fastener torque is excessive.
