Trimble -Electrical design query

Hi all,


In Trimble, Pro Design UK, for carrying out the cable calculations for Street lighting  do we have to really use GROUPING option in the calculations? How does this help in the calcs for a single phase or a 3phase supply ?

    Many thanks for your reply. 


    Yes , i have more than 3 cable running in a duct all of them 10sqmm. Do we have to really specify grouping for cables running together in ducts as we do a worst case design?
