During the repair, lay the hidden wiring is most correct after the end of the wall plaster, but before the installation of drywall sheets. In parallel with electrical wiring at this time, the rest of the wires must be laid: the Internet, TV, etc. D. The article discusses the laying of electrical wiring in concrete walls.
For this work, the following will be needed:
– cable;
– sockets;
– dose boxes;
– switches;
– punch and set of nozzles;
– Protective glasses and respirator.
Marking the location of wires and sockets
On the walls, it should be noted the location of all points of switches and sockets. It should be noted how the strokes will be laid under the wires, draw the entire scheme. The wires are laid only strictly horizontally or vertically. All strokes for other types of wires should be located at a distance of 15-20 cm from electric wires, their intersection strictly at a right angle is allowed.
Relays that may be needed can be purchased at the link/Products/Automation/Programmable-Relays/in the UNISET online store.
Stroobes in the walls
For walls, it is necessary to stock up in advance with a powerful perforator with a set of necessary nozzles for stroke of concrete, shock long drills of 22 or 26 mm in diameter and crowns specifically for the installation of dose boxes and sockets. You can use a grinder with a concrete disk, but although the work will be done faster, there will be much more dust. It is advisable to do this in protective glasses and a good respirator.
Basic rules when cutting out the strobes:
When turning the sidelines by 90 degrees, do not make a sharp turn. It should be smooth and equal to about five cable diameters. In the case of laying the wire under the ceiling, you need to fix it or put it in a special box.
If you need to put several electrical wires in parallel, you can make one large strobe.
If there is a grinder, it is necessary to make two parallelly going on the marking of the stroke at a distance of 25 mm, and the middle is knitted with a perforator with a special spatula.
Laying wires
The wire before laying must be rolled up. The wire is laid from the long room. Do everything in stages: they laid the wires from sockets to the main dose box in the room, launching for lighting began. Mark all the wires with an ordinary black marker so as not to get confused when connecting in an electric shield. From dose and mounting boxes, wires should stick out 30 cm for stock. For an electrical panel, a supply of 1 m for each wire.
After the laying end, check everything. Then put the strokes and go to the next room. When everything is laid and the ends of the wires are brought to one point in the hallway, it remains to be brought into an electric shield or the main dose box and the work was completed.
