Question about pull box sizing. If I have a wall of a box with angled and straight pulls the largest conduit being the straight pull. I know that for straights we would use the x 8 method. My question is for the angled pull calculation we are supposed to use the largest pipe x 6 plus the sum of other conduits. If the largest conduit is a straight pull do we use that conduit x 6 OR the largest angled pull conduit? Then the sum of the remaining conduits which would include the larger straight pull conduit.

From what I understand each wall in the box must be calculated on it's own. So I would say the straight pull conduit would be included in the calculation if it enter the box on the same side as the angle pull conduits

Don't forget the 6x between conduits that contain the same conductors where there is an angle pull.

Conduit entries. I.e. the hole you cut before you connect the conduit. No need to anticipate the exact size of the termination fittings when constructing it.
