DIY wiring

Do-it-yourself replacement of electrical wiring in an apartment, private house. Save time and money.

If you started an apartment or house repair, it is advisable to change the electrical wiring. Why it is desirable, because in the 70-80s no one counted on the electrical equipment that is now used in our apartments, and even more so in houses, and repairs were usually made cosmetic.

Nowadays, a lot of household appliances have appeared, such as washing machines, coffee makers, electric kettles, microwave ovens, electric ovens, bread machines, you can list the names of this equipment for a long time, and the question arises of how the old electrical wiring can withstand this technique, with an old electrical panel. For this reason, it is necessary to replace the old aluminum wiring with a new one, preferably copper.

It is best to start wiring from the back room, the closer you get to the electrical panel, the more wires you will have, and since most likely you are a beginner electrician, it will be easier to do the job and there is no need to be afraid.

Start by taking a tape measure, chalk or a construction pencil and drawing thirty centimeters from the floor to the centerline, seven centimeters wide and seven centimeters high, in these squares you will have sockets if you have more than one socket, but several, then draw not a square, but a rectangle at the rate of seven centimeters per socket.

We continue to draw lines from the squares to the ceiling and along between the wall and the ceiling to the doorway. Strobes are cut along these lines with an angle grinder. After marking outlets, we mark places for switches.

How markup is made when installing wiring

We draw squares the width and height of the rosettes, retreating from the floor to the axis of the squares of ninety centimeters, then we retreat from the floor two meters thirty centimeters and draw an axial line on which we draw a rectangle nine centimeters high and twenty centimeters wide, in this place there will be two distribution boxes into which all wires from sockets and switches will be reduced, one box for sockets, the other for lighting.

Next, we draw a line from the switch to the junction box and to the ceiling, to the junction boxes we also draw a line from the future lamp. From the junction boxes, the wires will go to the power panel.

After marking, take a grinder with a diamond disk (diameter 230 mm), do not forget glasses, gloves and a respirator and cut out squares, rectangles five and six centimeters deep, then cut a groove three and four centimeters deep.

After everything is cut, you need to knock out the strobes and openings for sockets, switches, junction boxes. Boxes (diameter 60 mm) in which they will be placed in the knocked out holes with the help of building gypsum sockets and switches and boxes (diameter 80 mm) that will serve as junction boxes.

How to connect and branch wires

From all outlet boxes, we lay the wires along the finished gates to one of the junction boxes. We also conduct wires from the switch and the lamp into the second junction box. Each junction box from the power supply panel should come with one power cable, then the wires are switched and insulated. The room is ready. All other rooms are made according to this principle.

After switching, it is advisable to apply voltage to the junction box and check the power supply in the outlets, and check the lighting operation, do not forget that 220 volts is life-threatening.

The voltage must be checked with measuring instruments. After checking, you can safely proceed to the finishing work. New wiring will last you for many years! Be sure to also see this article: Eight golden rules for repairing apartment wiring.
