Since the National Electricity Code Utilization (hereinafter CNE-U) does not provide a sequential procedure to calculate the minimum sections of low voltage cables (hereinafter BT), a didactic flow chart was developed, based on the IEC 603645standard. 52: 2009. This consists of two parts: the first allows us to obtain the general correction factor, while the second helps us to choose the section of the cable, checking it with the voltage drop formula, which should not exceed what is recommended by the CNE -OR. For application purposes, we use our flow chart to check its functionality, finding the sections of the cables to contrast them with those already installed in pavilion B of the National Technological University of Lima Sur (hereinafter UNTELS); obtaining agreement with the calculation design and some variations in certain circuits. With this we demonstrate its optimal use for the calculation of cable section and provide a solution to the lack of a methodology to choose cable sections in LV electrical installations.
