The modern market offers a huge number of consumer appliances, but, unfortunately, is not always possible to connect our “home helpers”. Wiring is not capable of withstanding all loads imposed on it. It can be replaced partially or completely. If the house is old, the wiring must change course completely. First of all, it affects the security of the home. This work is very time-consuming and requires special skills. You must first determine the location of the old wiring, then to remove it. There are special devices. Then, it is best to draw a schematic plan of the passage of the wiring. It is desirable to sketch the location of electricity cables in relation to the floor or ceiling. This is done in order to avoid damaging the cable, if a couple of years have to drill the wall. There are several ways of laying electric wires: the hidden and open. Open wiring is used in buildings such as wood. The wires are placed in a box and run along the wall. Closed wiring is used in brick and reinforced concrete buildings. The wires are placed in channels and obscure the plaster. disassembling sealed wiring is much heavier than the open. If you change the wiring of closed type, then this must be the puncher open channels in which lies the old wiring and pull it out. Before you begin, you must select the cable. There are two types of cable: aluminum and copper. It is best to use copper, but its price is much higher. Over time, aluminum loses its plasticity and breaks. When choosing an electric cable is necessary to consider section wire strands. If the wire cross-sectional area is large, the value of power consumption will be higher. There are established standards for residential buildings. In calculating the cross wire strands taken all the power of electrical appliances and consists, not forgetting to add to each of them with 100 watts, so the result was the most faithful. The resulting pouch is divided by 220. As a rule, the result is 12-14 A. Such a result is enough to live section of 1.5 mm. If the result was above the allowable, you should think about closing the electrical connection to several parallel lines, wiring, circuit breakers equipped. When installing the electrical wiring is best to use copper one-and two-conductor cable type and PUNP VVG with a range of 1.5 mm. Cable type VVG consists of several veins and easily bent, so it is more convenient to use during installation. You will need to purchase circuit breakers, non-flammable (used to protect wiring from mechanical damage), a box. When working with electrical wiring needed tools such as hammer, Bulgarian, screwdriver, pliers, cutter, terminal blocks, flashlight, knife, insulating materials. When everything is ready to work, you can begin to replace the wiring. The first step – it’s de-energizing your home from electrical current. After the old wiring is dismantled, it is possible to use the old channels for new gaskets. Installation can take place in parallel to the shield of the old wiring, followed by a gradual connecting outlets and switches. Any other way, when a Tbox connects the new wiring to the old. It is not advisable to connect aluminum and copper wire, because the galvanic couple is formed, which will lead to heat and arcing contact. In such cases, temporary connections use special adapters. Term use of such compounds is limited. Following the installation, you must use a tester to check power lines in the absence of a short circuit. Next, connect the line to the supply voltage and phase check performance. Electrical work must be carried out in compliance with all the normal safety as it affects life.
