How to calculate the wiring
The calculation involves determining the necessary wiring cross section and makes use of wires and cables. Ultimately, wiring made of selected materials must comply with the fire and electrical safety.
You will need
calculator
Instructions
1. To determine the introductory section of the power cable is necessary to calculate the total capacity of all planned to use energy consumers (household appliances, heaters, electric boilers, stoves and ovens, lighting), and multiply it by a factor of 1.5. Even better - 2 to create a margin.
2. As is well known, passing an electric current through the conductor (and it is the greater, the more power the powered appliance) causes heating of the conductor. Acceptable for the most common insulated wire and cable heating is 55-75oS. Based on this, and selected cross section of the cable opening. If you calculate the total power load does not exceed the next 10 - 15 kW, enough to use a copper cable with a conductor cross-section 6 mm2, aluminum - 10 mm2. By increasing the load power by half-section tripled. 3.Privedennye numbers are valid for a single-phase power cable laying open. If he is laid hidden cross-section increases in half. When the three-phase wiring for power consumers can be doubled if the laying open, and 1.5 times at a hidden gasket.
4. For electrical sockets and lighting groups traditionally use wire having a cross-section of 2.5 mm2 (sockets) and 1.5 mm2 (lighting). Since many kitchen appliances, power tools and heating devices are very powerful energy consumers, to put them to supply the individual lines. There are guided by the following figures: a wire having a cross section of 1.5 mm2, is able to "pull" a load of 3 kW section 2.5mm2 - 4.5 kW to 4 mm2 allowable load capacity for 6 kW, and 6 mm 2 - 8 kW .
Helpful advice
Determine the required cross-section is not too difficult. This will require a minimum knowledge in the art, a calculator, and at least a rough plan of the electrical household appliances. It should be clear that any wiring is divided into two parts - introduction (power) and the rosette-lighting.
