Zoeller 10-1403 Duplex Water Tight Junction Box

Product Description

The ZOELLER 10-1403 is a duplex, water-tight junction box designed for use in pump control and sump or sewage pump installations. It ships preassembled, reducing setup time on the job. The enclosure carries a NEMA 4X rating, making it suitable for both indoor and outdoor environments where moisture, dust, and corrosion are concerns. The 10-1403 includes three cord seals and two pump cord seals, and is built from high-impact, corrosion-resistant materials that hold up in wet utility environments where licensed electricians and pump service technicians work regularly.

This junction box is well suited for residential and light commercial pump system installations, including sump, effluent, and sewage pump applications. The NEMA 4X-rated enclosure handles direct water exposure, making it appropriate for basement, crawl space, and outdoor pump pit installations. Its preassembled design allows technicians to complete wiring connections quickly without field assembly of the housing components. Installers working with duplex pump control systems will find the included cord seals accommodate standard pump and control wiring runs.
