ENCLOSURE
NEMACO™ offers SubPro™ submersible waterproof electrical enclosure & junction box designs that are t IP-rated solutions (IP67, IP68) and NEMA 6P when the installation environment goes underwater. The NEMA 6P and IP68 rated enclosure, junction box and large floor mount cabinet are rated and designed for full water submersible. The NEMA 6P and IP68 enclosure configurations are designed to match the submersion depth, duration, and certification requirements for each application. Every NEMA 6P & IP68 unit is tested for 24-hour submersion at 15+ feet to validate watertight integrity before leaving the facility.
The IP67 enclosures are designed and tested for temporary submersion per the IP rating system. All the submersible enclosures including IP67 enclosures can be customized with pipe fittings and cable glands.
The metal submersible enclosures and junction boxes are UL Listed for most sizes and configurations. Submersible FRP fiberglass enclosures (electrically non-conductive) are ideal for many infrastructure requiring chemical or a non-conductive enclosures for safety. The submersible waterproof enclosures are a specification-ready choice for coastal, utility, flood-prone, and subsea installations where long-term sealing performance is non-negotiable
