The chart counts with 60 % usage of inner trunking cross-section. If the filling is different, you must take into account the way of mounting and the requirements of ČSN 33 2000-4-43, ČSN 33 2000-4-473 and ČSN 33 2000-5-523 standards. These standards define the current-carrying capacity of the conductors and cables respective to their way of mounting, arrangement and surrounding temperature.
