Correctly connect new electrical appliances
Did you buy a brand new washing machine or a vacuum cleaner? Now it's important to make sure that your new thing serves you faithfully for many years.
Old household wiring is designed for power up to2,2 kW, and modern household appliances create a total load, much higher than this figure, because only one washing machine consumes up to 2 kW. Therefore, you can not do without replacing the old counter. If the total capacity of the electrical appliances included in the network exceeds the permissible value, this will trigger the activation of the automatic protection system and the switching-off of the electrician in your home or apartment. Therefore, buying household electrical appliances, it is better to calculate in advance whether the automation will withstand the entire load.
Do not forget also that for each appliance you need a suitable socket. The so-called euro-sockets are designed for strengthcurrent in 16 A and power up to 3520 watts, while the old domestic sockets will withstand only 6.3 A of current and 1386 watts of power. In addition, there are more holes for plugs in eurosockets than in domestic ones, therefore it will not be possible to connect new imported equipment to the old outlet, and old domestic appliances to the euro outlet, without special devices.
Such household appliances as refrigerators, washing machines, computers, heaters require a mandatory grounding, otherwise an ungrounded device for anydamage may result in electric shock. Therefore, most modern household electrical appliances are equipped with a neutral protective wire and they are supplied with a special socket with a third grounding contact. If there is no zero wire, then it is necessary to ground this device yourself to a special terminal in the shield. If such a terminal is not present, then it is necessary to lay the main line from the flap on the staircase. And never connect the ground wire to the central heating pipes, water pipes and even more to the gas mains.
When installing electrical appliances take into account the diameter of the wire. The load in 1kW requires a wire with a diameter of 1.57 mm2, proceeding from this and it is necessary to choose the necessarydiameter of section. Because the conductivity of the aluminum wires is approximately 62% of the conductivity of copper, the diameter of the section for aluminum wires should be chosen more than for copper at the same load.
To have your apartment or house equippedelectric household appliances with the latest technology, go to the issue of selecting and installing these devices very carefully. Be sure to think in advance about placing all kinds of cables and wires, which you will certainly need to install home appliances in the house.
