Midwest Tool M281CB1 200A Surface Mount Metered Ring Service

Product Description

The MIDWEST TOOL M281CB1 is a surface mount service entrance enclosure rated for 200 amperes at 120/240 volts, single-phase. It is a metered ring type unit built for residential and light commercial electrical service installations. The enclosure is constructed from G90 galvanized steel with a zinc-coated finish, meeting NEMA 3R standards for outdoor use. The first position circuit breaker type is CB4200H. All components arrive factory wired and assembled, reducing field labor time. Terminals accept both copper and aluminum conductors across multiple wire ranges, and the unit carries UL approval with compliance to NEMA and NEC applicable standards.

This unit is suited for surface-mounted service entrance applications where a metered ring configuration is required. It is appropriate for single-phase residential services and light commercial installations where the utility meter socket and main disconnect are integrated into one enclosure. The cabinet dimensions are 14.375 inches wide by 4.75 inches deep by 28.625 inches tall. Loop-feed terminals provide flexibility for multi-position service configurations. The broad range of concentric knockouts accommodates varied conduit entry layouts common in field installations.
