Wall outlet box
In electrical installations, a connection unit installed under the plaster or in lightweight walls is referred to as a wall outlet socket, which is used to accommodate clamping or connection points in order to connect stationary equipment (mostly lights ).
description
The shape of the wall outlet box is similar to that of a ship's hull if it is intended for flush-mounted installation. In the case of a planned installation in lightweight walls in dry construction , it is made of fire-retardant material and round so that the hole required for assembly can be made with a hole saw .
The connecting terminals to be inserted therein, such as luster terminals or other types of terminals , are used to electrically connect the permanently installed supply line to the connection line of the equipment. The wall outlet socket also serves to protect the plaster surrounding it from damage when the equipment is connected (repeatedly). Since the terminals are inside the box and thus under the wall surface, problems with small or particularly flat lamps are avoided, which often do not offer any space to accommodate the terminals. Furthermore, in the case of installation in a lightweight construction wall, thanks to its fire-retardant and possibly airtight construction, it serves to withstand any smoldering fire that may arise at least for a specified time, which is specified in the respective fire protection regulations, and to ensure its function.
A wall outlet box is about 60 mm high and 30 mm deep and just as wide in its flush-mounted version. In its version intended for the lightweight construction wall, it has a diameter of about 35 mm and a depth of about 45 mm.
