Wire Ampacity Calculator Enter the information below to calculate the maximum allowable ampacity for current-carrying conductors. The wire size calculator uses 75°C for PVC and 90° for XLPE. A common mistake in sizing wire is to turn to the NEC wire size charts to determine how much amperage a wire can safely handle. For Ambient Temperatures Over 30° C, 86° F, multiply the ampacities shown above by the appropriate factor show below: 1 The load current rating and the overcurrent protection for conductor types shall not exceed 15 amperes for 14 AWG, 20 amperes for 12 AWG, and 30 amperes for 10 AWG aluminum and copper-clad aluminum Calculate Low Voltage Cable Size and Transformer Wattage Rating. marine 12v wire size calculator
