Ability to add multiple set of conductor in a single conduit
Example:
For 400A feeder:
(2) 3"C, 3-250kcmil AL, 250kcmil AL N, #1 AL G
(1) 4"C, 6-400kcmil AL, 2-400kcmil AL N, #1 AL G
Instead of each set take (1) conduit, would be good to get multiple set into a single conduit. This is mainly because installing (1) 4" conduit is cheaper than (2) 3" conduits.
