What to do in repairing old home
When you plan to renovate your old housing, it is good to consider replacing the electrical system because such an action will avoid possible future problems.
As the number of home appliances grow, if the old wiring has a certain capacity, the inclusion of additional appliances such as: a washing machine, a dishwasher, an oven, and a boiler will exceed that capacity and a possible overloading of the network might happen, the experts indicate. That is why they recommend replacement of the old fuses with automatic circuit breakers that will provide greater protection to the electrical system. Depending on the number of devices that will be used, the power of each switch is determined.
Electrical installations in panel blocks are set for specific load capacities, ie. simultaneous work of a fridge, an oven and a TV. It is important to examine the capacity of the internal electrical wiring and to consider its enlargement. Apart from the change to a new electrical system, the users should pay attention to the electric keys and sockets. There are different models, such as with rigid or resistant to high temperature plastic that ensure reliability and wiring safety. If your home is 35-40 years old, this means that the conductors of the electrical installation are old and that could possibly cause accidents or poor quality of the electricity in the house. So the best advice is to change it. Depending on the devices (equipment), which will be joined to the network, it is necessary to consider the conductors, as well as the corresponding number of circuits for the specific electrical installation. When there is an upcoming installation or replacement of an electrical wiring, you should seek a competent electrician who will prepare the most suitable wiring scheme for your home.
Otherwise, there is very high likelihood of accidents. In order to facilitate the installation of the new electrical wiring, sills can be used, through which the cable routing is more convenient and easy. It is good to know how exactly the wiring in your home is situated. Otherwise there is a danger when performing simple tasks, such as putting a picture on the wall, because it can cause electric shock by touching a cable from the electrical installation. In case you do not have information about the exact location of the electrical wiring in your home, you can get detectors, no matter if they are built into a wall or behind a sill. For greater safety they can be installed in the surge protection panel, which fights against power surges.
In accordance with the new requirements an overcurrent and overvoltage protection must be placed in the electrical panels. In order to avoid an overload of the electrical system, special sensors could be placed, which “understand” when there is a person in the room and automatically activate the power supply on their own. The internal wiring covers all the electrical equipment from the panel, including each electrical switch in the dwelling. In residential buildings with many apartments the power supply of the floor lighting and the elevators is part of the internal installation of the condominium. The maintenance of the internal wiring is responsibility of the owner of the property. According to the National Statistical Institute data shows that the majority, 73% of residential buildings in Bulgaria and internal networks are built in the period between 1946 -1990. The experts recommend examining the internal electrical wiring in homes, and if the installed capacity is increased, to undertake repairs, in order to ensure maximum operational safety and good quality of the home electricity.
