I have an installation where multiple Belden (29500), 4 conductor, 16 AWG, VFD cable is being installed in wireways. There is a total of 50 drives so I need to size the wireways properly. The cable is used for power from AB 160 drives to continuous duty gearmotors from 1/2HP to 1HP. When I derate for number of conductors in the wireway do I count each conductor in the cable or the whole cable as one conductor?
I know to use the whole cable area for the 20% fill.
