Some junction boxes have specific instructions for weep holes. For scepter
PVC junction boxes you can drill a 3/16 inch hole in the bottom to make a
nema 4 enclosure nema 3R. The instructions are etched into the bottom of
the box.

Hi Glenn;
Ahh that's new from NEC 2014. Thanks for pointing that out, and scratch
my previous comment based on experiences in 2008.

Eric,
I have been busted by inspectors for "modifying a UL device in a way
that is not permitted in its listing", or something like that. While
weep holes make all the sense in the world, and I have commonly seen
1/4" holes drilled in LBs for ground wires, etc; one out of ten AHJs
might not like it.
Eric,
I like your idea of drilling the weepage holes as long as
they are not big enough to allow critters like wasps to make a home
inside the J-box. We will use aluminum tape on unused mounting holes in
the back of the box for the same reason. Lurkers welcome.
