The electrical enclosure is the cabinet of electrical or electronic equipment, which is used to install switches, knobs and displays to prevent equipment users from electric shock and protect the contents from environmental impact. The enclosure is the only part of the device that can be seen by the user. The electrical enclosure is designed for its practical requirements and pleasing to the eye. Regulations specify the characteristics and performance of electrical equipment enclosures in hazardous areas, such as petrochemical plants or coal mines. The battery packaging may put forward many requirements for heat dissipation, RF interference, classical discharge protection, as well as functional, beautiful and commercially limited enclosures.
