Other examples of NEMA 3R enclosures are virtually all meter bases,
outdoor service boxes, pole mounted disconnects, air conditioner and
other roof mounted disconnects as well as wiring enclosures for changing
wiring methods from underground conduits to building interiors, which
generally make the connections with standard wire nuts.
Electricians use NEMA 3R enclosures a lot, and don't use sealed
connectors inside. As William points out, NEMA 3R may be superior
to gasket sealed boxes in that 3R allows for any condensation to
evaporate readily. <br><br>
