Well Roger heres one with 75# - 4 inch conduits straight thur pulling mostly 750 mcm .http://i611.photobucket.com/albums/tt195/stringking/P1010093_02.jpg
Our two piece box we have the pvc cups installed with bells flush on inside so there sealed you just glue & push in the pvc conduit .
We pull straight thur no need for rigid !
Or the engineer is thinking its like when we poke thur a deck or under a slab we change from pvc to rigid for stress and a good seal between the the barriers of earth and above slab so the pvc does not crack from the movement of slab expanding and contracting .
Or maybe its just his way of writing the specs or copying the specs from 1954 we see the same over and over 1600 spec never change much its about time to write some new stuff.
