(13) A junction box contains two trade size 2½ raceways on the left side and one trade size 2½ raceway on the right side. The conductors from one trade size 2½ raceway (on the left wall) are pulled through the raceway on the right wall. The other trade size 2½ raceway conductors (on the left wall) are pulled through a trade size 2½ raceway at the bottom of the pull box. What's the minimum distance from the bottom wall to the top wall?
