What is a double drawer?
The double socket is a few drawers built in tandem, sometimes on the other and sometimes side by side. It is usually installed on the wall, but can also be installed on floors and ceilings. Technological advances over individual sockets were introduced in the US around the mid -20th century, which offers users the ability to connect two devices where only one could be connected. This was a huge advantage at a time when the rooms were commonly limited and dangerous taps and extension cords.
In general, double sockets offered for use in the US must meet the standards determined by the National Association of Electric Manufacturers' Manufacturers (NEMA®). In modern use of the household, individual sockets are generally limited to special objects, such as 240 V outlets used for electric dryers or ranges. Industrial equipment can also have more of these special stores, which are rarely configured in tandem. Double sockets in the US are configured on the second onsecond; Configurations side by side are more common in Europe and Asia.
In the new design, double sockets are generally installed in plastic connecting boxes that are nailed on wall studs. They are usually installed from 12 to 18 inches (30.48 - 45.74 cm) above the floor, but there are many cases where they are located at other heights, especially above kitchen and bathroom counters. The electrical cable is supplied with the back of the box and securely closed and the individual wires are connected to the double socket, which is then secured inside the connecting box. Before installation, openings are cut in the walls to adapt to the connecting boxes. The coverage with holes for both drawers is installed to mask the holes in the wall and protect from random contact with the exposed supply metal.
Installations of double -backed trees in the existing construction are more complicated. A hole of neighbor must be cut in the wallWith a pin and a new cable runs behind the wall using a special tool called snake. Other holes may be required to facilitate the cable accident between placing the new output and energy source. In the first hole is installed a new intersection, after which the installation of a double socket will take place along the same lines as with a new construction. Once the socket is installed and tested, the cover plate can be installed and all damage to the wall repair.
In addition to providing additional outlets for connecting multiple electrical devices, double sockets offer some connection options that provide the user with some interesting skills. Two individual sockets are designed with metal strips that connect the two, so they are part of the same circuit; When one socket is properly connected, both sockets are under voltage. In this way, most double drawers are configured and used. However, the stripe can be deliberately broken, and reconfigure the duplex socket as two independent sockets.
the mostA more difficult reason for the configuration of independent sockets in the double socket is to provide checks over one socket wall switches. One socket is conventionally connected to a normal power supply, so the device is connected to them by their own power switches. The second socket is connected to the wall switch. When the wall switch, socket or socket to which it is connected is on voltage.
switched sockets often occur in larger rooms without above -ground lighting. The lamps connected to the switched sockets are turned on and off by activating a single wall switch. When there is more than one switched socket in the room, the convention is to connect identically because of comfort; This means that the switched sockets correspond to either the upper socket or the bottom socket. As is the case whenever it is electrical work, the strength should be disconnected - and best locked - for the source until the task is completed. In addition, some jurisdictions may regulate such workand may require permission.
