when sizing a pull box for conduits and cables larger than #6 for angled pull installation the dimensions of the box need to be 6x the largest conduit diameter + the sum of the remaining, so for two 4"C. I would need approx 28" clear, there is also the distance from the entering conduit to the exiting must be 3x the conduit diameter (going from memory). my question is in a box where I am splicing conductors does one still need to comply with the distacne from the conduit entry on one wall and the exit on the other as the wire will not be pulled from one into the other but rather spliced in the box?
