Wire decking consists of wire mesh supported by metal supports and is intended to be load-bearing. The mesh is usually welded to the supports, but may be attached in other ways as well. In commercial and industrial applications, the wire mesh usually has a minimum wire gauge of 0.105 inches when round wire is used. The most common shelf size is ...
The construction features of an electrical room vary depending on the scope of the equipment to be installed. Floors may be reinforced to support heavy transformers and switchgear. Walls and ceilings may have to support a heavy cable tray system or busbars. Additional ventilation or air conditioning may be needed, since electrical apparatus ...
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
A wall plan is a drawing which consists of complete details with dimensions (with an accuracy of an inch) about all four sides and ceiling of each and every room in a building. It is drawn with the help of a floor plan as the basic input. The main contents in a Wall Plan are: Electrical points (like Switch Board Position, Light Position, etc.)
A similar, usually wall mounted, container used mainly to accommodate switches, sockets and the associated connecting wiring is called a pattress. The term junction box may also be used for a larger item, such as a piece of street furniture. In the UK, such items are often called a cabinet. See Enclosure (electrical).
Ceramic bushings protected each wire entering a metal device box, when such an enclosure was used. Loom, a woven flexible insulating sleeve, was slipped over insulated wire to provide additional protection whenever a wire passed over or under another wire, when a wire entered a metal device enclosure, and in other situations prescribed by code.
The goal was to preserve the materials of the generator (walls and electrodes) while improving the limited conductivity of such poor conductors to the same level as a plasma in thermodynamic equilibrium; i.e. completely heated to more than 10,000 kelvins, a temperature that no material could stand.

Such a region is commonly known as a U, for unit, RU for rack unit or, in German, HE, for Höheneinheit. Heights within racks are measured by this unit. Rack-mountable equipment is usually designed to occupy some integer number of U. For example, an oscilloscope might be 4U high. Rack-mountable computers and servers are mostly between 1U and 4U ...
