About This Item
C37.20.2-1987 is a technical standard for Type Cubicle Switchgear in power, energy, and industrial applications. It addresses the design and construction of cubicle-style switchgear used to organize and protect electrical equipment in controlled installations. For engineers, specifiers, and procurement teams, this standard helps define a common basis for equipment expectations, which supports safer selection, clearer comparison, and more consistent performance in medium- and high-duty electrical systems.
About C37.20.2-1987
This standard focuses on Type Cubicle Switchgear and the technical requirements associated with that equipment category. In practice, it is used to guide how cubicle switchgear is arranged, built, and evaluated so that installations can meet expected electrical service conditions. C37.20.2-1987 is relevant when equipment needs to fit within a defined switchgear structure and maintain acceptable performance, durability, and operational consistency under power system demands.
Where is C37.20.2-1987 used?
C37.20.2-1987 is commonly applied in substations, industrial power distribution rooms, and utility-focused electrical installations where cubicle switchgear is part of the system architecture. It is also useful in projects involving feeder control, switching, and protection equipment housed in standardized cubicles. The standard supports planning and specification work for facilities that rely on organized switchgear assemblies to manage electrical power safely and reliably.
Importance in practice
Using C37.20.2-1987 helps bring consistency to switchgear design and procurement, especially where Type Cubicle Switchgear must meet defined technical expectations. It can support compliance checks, reduce ambiguity in equipment selection, and improve coordination between designers, manufacturers, and buyers. By setting a recognized reference point for construction and performance, the standard may also help lower installation risk and make maintenance and replacement decisions more straightforward over the equipment life cycle.
