8x8 wireway calculate control cable fill

[pjkPA]

I have to put approx. 90 control cables (20ma) in a wireway.
Need to know what the fill capacity is.
Is it 20% of area?
8x8=64x.2=12.8 cu. in max fill?
Thanks for any info ..looking in code now.

12.8 sq. in. (not cu. in.) is correct. See 376.22(A) for metal wireways and 378.22(A) for nonmetallic wireways.
