After all we are calculating the current carrying capabiltiy for one conductor of the three single-core conductors inside the PVC duct.

IEC IEC Webstore The current carrying capability of the power cables rely largely on the installation conditions and material properties.

In this work, the influences on ampacity of conductor size, soil thermal resistivity and ambient soil temperature for underground uec are shown. IEC calculations for three single-core cables in trefoil in 9 way 3 x 3 duct bank its great that you have time to respond, i appreciate it but unfortunately i dont have the experience that you have and would like to know how to explain the usage of the equations idc the standard.

It is simplified for d. Reference operating conditions and selection of cable type. It can probably be appreciated by now, that in typical real life , this can be quite a complicated calculation. Thanks for the feedback. While software is a great asset, many times Before, if you would introduce the calculated T1, T2 [actually your T3 is T2 as per 2.
