The NVENT A20H16ALP is a NEMA 4 rated electrical enclosure designed to protect electrical components from windblown dust, rain, splashing water, and hose-directed water. Built for 6 inches of interior depth, this enclosure provides ample space for control boards, terminal blocks, and other electrical equipment in demanding environments. Licensed electricians and industrial maintenance technicians install this type of enclosure in commercial and industrial applications where moisture and contaminant resistance is required. Its NEMA 4 rating makes it a standard choice wherever environmental protection of electrical installations is specified by code or project requirements.
This enclosure is suited for use in commercial, industrial, and heavy-duty trade applications where electrical components must be shielded from wet or dusty conditions. Typical installation scenarios include control panel builds, motor control centers, junction box applications, and field equipment installations. The 6-inch depth accommodates a variety of component layouts, making it a practical choice for panel builders and electrical contractors working on both new construction and retrofit projects.
Designed as an OEM-style replacement or new-installation enclosure for NEMA 4 rated electrical panel and junction box applications in commercial and industrial environments.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits before opening or mounting the enclosure and verify power is off with a meter before beginning work. Ensure all conduit entries are properly sealed with appropriate fittings to maintain the NEMA 4 rating after installation. Do not modify the enclosure in ways that compromise its environmental sealing.
