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.
Round cable entry plates are usually produced in metric standard sizes (M16 – M63) Since cable entry systems are utilised in many different applications, it is very important to comply with standards like e.g. IP rating (according to EN 60529), UL recognition, DNV-GL listing (for marine applications), national or European railway standards or ...
A toilet-roll holder, also known as a toilet paper dispenser, is an item that holds a roll of toilet paper. Common models include a hinged length of wire mounted horizontally on a wall, a thicker axle either recessed into a wall or mounted on a frame, or a freestanding vertical pole on a base.
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]
A basic litter box and scoop. A litter box, also known as a sandbox, cat box, litter tray, cat pan, potty, pot, or litter pan, is an indoor feces and urine collection box for cats, as well as rabbits, ferrets, miniature pigs, small dogs, and other pets that instinctively or through training will make use of such a repository.
The type of thermoplastic, the dimensions of the conductors and the colour of their individual insulation (if any) are specified by the regulatory bodies in the various countries concerned. [1] Thermoplastic-sheathed cable is more vulnerable to rodent damage and accidental mechanical damage than wiring within electrical conduit or armoured cable.
Pedestals are used for CATV (known as a cable box in such a situation), telephone, passive optical networks, and other telecommunications systems. A pedestal is generally a sheet metal or plastic housing that encloses a passive termination block. The pedestal is usually about 3 feet high and has a diameter of less than one foot, with a circular ...
The cable connectors and sockets are keyed and colour-coded, according to the voltage range and frequency used; common colours for 50–60 Hz AC power are yellow for 100–130 volts, blue for 200–250 volts, and red for 380–480 volts. The blue fittings are often used for providing weather-proofed exterior sockets for outdoor apparatus.
