9 Sep 2010 r = radius of the wire or cable d = diameter of the wire or cable. Calculation of the diameter r, entering the cross section A: There is no exact formula for the minimum wire size from the maximum amperage. It depends on many circumstances, such as for example, if the calculation is for DC,. AC or even for
Electrical Installation Calculations: Basic. Calculate the size of trunking required for this installation. Step 1: Calculate the cross-sectional area of cables using values from Table A csa of 1 mm2 cable including insulation. ?2.92. 4. = 6.6 mm2. Twelve cables: 12 ? 6.6 = 79.2 mm2 csa of 1.5 mm2 cable including insulation.
