Information on the purpose of the calculator

The electric cable calculator is designed to calculate and select the cross-section of cable products by current and power, taking into account safe operation at the selected mains voltage. Since the wrong choice of cable cross-section can lead to a fire, for the design of electrical networks, be sure to contact specialists in your region.
