What is a wall plug?
The term “wall plug” has two different meanings, one in the context of residential and commercial electrical circuits and the other in the context of general building supplies and building materials. The electric wall, also known as an output or container, is a point of connection between the electrical equipment of the plug -in and the building circuits. From the point of view of building materials, the wall plug is a plastic or metal sleeve that can hold the screw in the wall that would not otherwise be able to support it. The proposals of the wall plugs differ from the region to the region around the world, because no individual standard has been adopted for tension in which electricity is supplied by energy companies. A country for which is 100 to 120 Voltůical and horizontal slots standard, while those for which the standard is 200 to 240 V. In the United States, the design of the container is determined by the National Association of Electric Manufacturers (NEMA) and its proposals are used in other North American countries.
In the construction industry other than electricity trades, the wall means the same as the anchor of the wall or anchor of the screw. Some wall materials, such as plaster, plasterboard and concrete, cannot hold screws. When driving a screw into these materials, it is necessary to drill a hole and put the plug on the wall to hold the screw. The hole must be deep and wide enough for the plug to fit firmly as the hammer drops and the screw strength is driven to secure against the sides of the hole.
The amount of weight that the bolt can support is depends on the material is made and its design. The conical plastic plastic wall can hold the smallest amount of weight and is often used to attach light shelves or pictures to the walls of plasterboard and plaster. If multiple maintenance power is required, usually a fastening element such as an anchor of a metal screw, winged or threaded plastic plug or minor is usually usedy screw that praised at the end. Usually, a wall plug made of lead is used if it is necessary to drive the screw into the concrete.
