Read the entire section...."Section 314.28(A)(3) Smaller Dimensions", allows
smaller conduit bodies and boxes _IF_ "... the box or conduit body has been
listed for and is permanently marked with the minimum number and maximum
size of conductors permitted." You'll usually find the marking inside the
conduit body. Or you can posssibly use a 4" x 4" x 24" trough.

Yep, there it is. Don't know how I missed it. What a relief. Thanks.
