In the electrical wiring of buildings, a cable tray system is used to support insulated electrical cables used for power distribution, control, and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in commercial and industrial construction.
The cable management needs at either end are different (see also: Structured cabling). Buildings and office furniture are often designed with cable management in mind; for instance, desks sometimes have holes to pass cables, and dropped ceilings, raised floors and in-floor cellular raceway systems provide easy access.
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. The enclosure is the only part of the equipment which is seen by users.
Cable entry systems are used for routing electrical cables, corrugated conduits or pneumatic and hydraulic hoses into switch cabinets, electrical enclosures, control panels and machines or in large heavy-duty vehicles, rolling stock and ships. Possible requirements can be high ingress protection rates or integrated strain relief. [1]

A small metal, plastic or fiberglass junction box may form part of an electrical conduit or thermoplastic-sheathed cable (TPS) wiring system in a building. If designed for surface mounting, it is used mostly in ceilings, concrete or concealed behind an access panel—particularly in domestic or commercial buildings. [2]
