Cable tray calculation formula
WebT = operating temperature of the conductor (°C) Surge Impedance The surge impedance of the cable can be calculated with the following formula: Where: Z o = Surge Impedance of the Cable (ohm) L C = conductor inductance (mH) C … Webfound. For example, a 10 AWG 3C 600 V cable is installed in an ambient temperature of 50°C. According to NEC 2014 310.15(B)(2)(A), the cable’s ampacity would need to be multiplied by a correction factor of 0.75, assuming the 75°C column was used in the ampacity table. The adjusted ampacity would be 26 amps. INDUSTRY EXAMPLE
