NEC 314.28 (B) (2) for angle pulls in a gutter requires 6 times the largest conduit plus the sum of the remaining conduits in the same row for the space across from the conduit entry. I have seven 1.25" EMT in a row which would calculate to 15".
But, I found the sketch from Mike Holt showing a conduit entry with (what looks like) five 500kcmil conductors and 6" tall wireway. Per my conduit sizing, that whould be a 3" conduit which would require an 18" wireway.
Does anyone know how Mike was able to reduce the wireway to 6"?
For my case above, is there a rule that permits a smaller wireway height?
