Copper ampacity table: GB copper ampacity table estimation method: Estimation Method: single copper busbar ampacity = Width (mm) X thickness factor double busbar ampacity = Width (mm) X thickness factor X 1.5 (empirical coefficient ) copper and aluminum row can also press the square of the number of years, usually copper should press 5-8A / square, aluminum should be calculated according to the carrying capacity 3-5A / square commonly copper: the copper used ampacity calculation method 40 ℃ When the copper-carrying capacity = row width * thickness coefficient row width (mm); thickness factor: When thick busbar 12 of 20; 10 is thicker at 18; as follows: [12-20,10-18,8-16 , 6-14,5-13,4-12]. double copper [40 ℃] = 1.56-1.58 monolayer copper [40 ℃] (based on cross-sectional size of the set) 3 layer copper [40 ℃] = 2 single copper [40 ℃] 4 layer copper [40 ℃] = single copper [40 ℃] * 2.45 (not recommended such choices, the best alternative profiled busbar) copper [40 ℃] = copper row [25 ℃] * 0.85 aluminum row [40 ℃] = copper [40 ℃] /1.3 such as seeking TMY100 * 10 carrying capacity: Single: 100 * 188 = 1800 (A) [check the manual for the 1860A]; bis Layer: 2 (TMY100 * 10) of carrying capacity: 1860 * 1.58 = 2940 (A); [check the manual for the 2942A]; three: 3 (TMY100 * 10) of carrying capacity: 1860 * 2 = 3720 (A ) [check the manual for the 3780A] above all calculations are accurate to the manual data quite close.
