.however, there are some caveats with outdoor boxes. However, if you have an outdoor-rated box, such as a NEMA 3R loadcenter cabinet, then you have to be careful to maintain that box's NEMA rating. For a NEMA 3R, in particular, you have to use a watertight hub fitting to enter the box anywhere above the lowest live part in the box. Drilling a drainage hole in high IP rated enclosures, is for condensation purposes, not for compensating for badly sealed glanding. Holes are drilled when these totally sealed enclosures are mounted/located in positions that will be subject to the occurance of condensation forming on the interior of these enclosures.
