Metal-Clad Switchgear is an assembly of units characterized by the following features: The main interrupting device is removable and arranged with a mechanism for moving it physically between connected and disconnected positions. It is equipped with self-aligning and self-coupling primary and secondary disconnecting devices. The interrupting devices, buses, voltage Transformers, and control power transformers, are completely enclosed by grounded metal barriers, which have no intentional openings between compartments. A metal barrier in front of the interrupting device ensures that when, in the connecting position, no live parts are exposed by the opening of an enclosure door. All live parts are enclosed within grounded metal compartments. The Metal enclosed switchgear assembly consists of multiple metal-enclosed, vertical sections. Normally the end sections are designed to allow for installation of future sections. Each vertical section consists of up to four individually enclosed breaker or auxiliary compartments. Compartments are sized to provide uniform height of each switchgear assembly. Various components such as circuit breakers, instrumentation and control equipment, transformers, relays, three-phase bus work, all internal wiring, connectors, and other supporting equipment are included in each assembly. These units can be directly coupled to 480V motor control centers if desired
