Terminal Boxes

Terminal Boxes are for use in converting from overhead to under-ground services and for multi-circuit wiring. The NEMA 3R enclosure provides protection for all terminations inside and provides a convenient, time-saving means of wire splices and connections. Midwest offers a full line of terminal boxes for 240 volt single phase and three phase, and three phase 600 volt ratings to meet your application requirements.


Typical applications, both indoor and outdoor, include inter-building wiring on farms, convenient splicing means for industrial use and commercial construction.
