Apartment Building

We always forget to think about how safe electrical wiring in the apartment, by inserting the plug into the outlet's new electric kettle firms 'Tefal'. And it is in vain, as the vast majority of household electrical networks of our homes are made under the old rules, when the wiring in the apartment was done under the design load only 800 1000 Tues Now, one above the kettle 'Tefal' or similar kettle of another firm picks up as much as 2 kW, and in fact apart from his apartment there is also a washing machine and vacuum cleaner. Therefore, the wiring in the apartment, enjoying loads of new household appliances, is a real danger for older residential electrical networks. It is true that in 1994 Russia adopted new safety standards for electrical and electronic equipment and in the 'Regulations for Electrical Installation' (PUE) took place accordingly. One key among these changes was that the wiring with two wires for intra grid has been replaced by three-wire, so that now the consumer must come three wires: phase, neutral and earth. This corresponds to increased electrical safety standards and norms of the iec (International Electrotechnical Commission), as well as the requirements that apply to networks of modern household appliances (not just imported). As is known, is now the main cause of the fire (except alcoholism) is a misuse of the powerful import electrical appliances, which requires electrical wiring in an apartment with three wires with separate protective conductor. Aggravate the situation still 'working' in the homes of old wiring and old fittings, designed for load A/220 '6 B ', while imported electrical fittings and a new domestic already bears the inscription '10 / 15 A/220 B '. This means that the fixture rated for maximum load current of 10 A at 220 V, while maintaining short-term overload current to 15 A (overload factor 1,5). By the way, the same overload factor is calculated our 'old' wiring and our 'old' fittings (at the last just did not have written that the current overload for her – 9 10 A). That is why the 'old' wiring in the apartment somehow, but Still coping with the increased workload.
