In general, a cubicle refers to a steel-based switchgear facility consisting of various sensors, switchgear, instrumentation equipment, terminals, etc. to smoothly operate and manage received power.

The various devices built into the cubicle are completely wrapped in steel to make them safe and are called a metal clad type, that is, a closed switchboard. ANSI and IEEE also define the Metal Clad type as a structure in which the conducting parts are completely sealed with a metal casing. In addition, JEM is equipped with circuit breakers, switches, and their operation, measurement, protection, and monitoring and control mechanisms for the switchboard, and is equipped with indoor wiring, accessory parts, and base structures for power generation, transmission, distribution, substation, and power. It is defined as a general term for devices required to operate a switching system, and is considered to belong to a wide range of switchboards that include various control boxes.
