Electrical installations inside residential buildings are installed stationary, so the choice of suitable should be paid to special attention. Isolated electric cables distribute electricity to the load, and this process should be performed with maximum safety. What should you pay attention to when choosing cables for electrical installations installed at home? Detailed information can be found below. Med as the best material for electrical wiring
Investors can choose cables of copper or aluminum wiring. Copper wires have much greater wear resistance. They differ in higher electrical conductivity, and are also completely resistant to bending or stretching. Aluminum cables are more brittle, less resistant to temperature fluctuations, in addition, they are more prone to overheating.
In private houses used for residential purposes, three -resistant cables with a cross section of 1.5 mm2 and 2.5 mm2 are most often used. They are mounted in a hidden installation, which at any time can be expanded or replaced without the need for walling. When choosing suitable cables for electrical installations, special attention should be paid to the properties of the cable. Its permissible maximum temperature should be at least 70 ° C, and the minimum -40 ° C. The insulation of the cores should be made of PVC plastic. Additional wiring protection
One choice of appropriate wiring for electrical installation is not enough. The wiring must be additionally protected to eliminate the risk of overloading the installation or its malfunctions and mechanical damage. The best solution that fully protects the cables and affects the safety of electricity, regardless of domestic conditions, is the use of cables in the corrugated pipe. Using this type of installation also reduces its assembly time. Channels for the input of electrical installation cables are usually made of corrugated pipes with a strength of at least 320n/5cm. It is possible to note that each electrical installation should be established in accordance with applicable norms and standards, and only specialists who have appropriate ones can perform the location of the wires and their installation. permission. pin up
