A few years ago say back in the late 1990's and on into the new century,many studies were being done by cable manufacturer's,IEEE guys etc, on cables used in 600v and less VFD service.When I quit following it(retired),it looked like 3 phase conductors and 3 symmetrical grounds with an overall shield was the direction it was taking and would become the preferred cable makeup.Did this ever come to the table as a must or highly preferred method?:-?
I don't even remember the reasons behind the studies.This would have applied to only the cable from the controller to the drive itself
