If that is expected to be a problem you need to drill weep hole in the bottom of the box. Bell box even partially filled with water usually leaves you with a device that if it is still working is questionable if you should still be using it. If it is supplied by a raceway that goes any direction besides down - it will get water from condensation in it around here. Then it will rust the mounting screws and terminal screws and you will be replacing the box, device and cover as all will be compromised in some manner. One 1/8 hole in bottom of box at installation prevents this from happening.Farther from any water that might get into the box.
I was going to suggest that possibility.Not knowing the supervisor I was willing to give him the benefit of doubt that he was challenging the OP to prove him wrong.
