An electrical enclosure is a cabinet for electrical or electronic equipment to mount switches, knobs and displays and to prevent electrical shock to equipment users and protect the contents from the environment. A cabinet is usually a box-shaped form either standing alone as a piece of furniture or built into or attached to a wall (such as a Medicine cabinet typically made of wood Electrical equipment includes any Machine powered by Electricity.

The enclosure is the only part of the equipment which is seen by users; in many cases it is designed not only for its utilitarian requirements, but also to be pleasing to the eye.
In the United States, the National Electrical Manufacturers Association publishes standards for the performance of various classes of electrical enclosures. The National Electrical Manufacturers Association or NEMA is a U The NEMA standards cover corrosion resistance, ability to protect from rain and submersion, etc. For IEC member countries, standard IEC 60529 is classifying the ingress protection rating (IP Codes) of enclosures. The IP Code defined in International standard IEC 60529 classifies the degrees of protection provided against the intrusion of solid objects (including body parts The IP Code defined in International standard IEC 60529 classifies the degrees of protection provided against the intrusion of solid objects (including body parts
Electrical enclosures are usually made from rigid plastics, metals, particularly steel and aluminum, and natural or processed wood.

Enclosures for some purposes have partially punched openings (knockouts) which can be removed to accommodate cables, connectors, or conduits. A cable is one or more Wires or Optical fibers bound together typically in a common protective jacket or sheath Where they are small and primarily intended to conceal electrical junctions from sight, or protect them from tampering, they are also known as junction boxes; the larger, street furniture type is often called a cabinet or, in American English telephone jargon, Serving area interface. An electrical junction box is a container for electrical junctions usually intended to conceal them from sight and to Street furniture is a collective term for objects and pieces of equipment installed on streets and roads for various purposes including benches, Bollards Post The serving area interface or service area interface ( SAI
