color:#1F497D'>I’m fairly confident that if the manufacturer does not specify
an angle for NEMA 3R (rainproof) that the default is vertical. In special cases
(e.g. Outback PSPV), the NEMA 3R tests are requested at an angle, but this is
fairly rare. Upshot is that NEMA 3R boxes normally cannot be mounted in the
plane of the roof, while NEMA 4 and up can be mounted in the roof plane since
many of these boxes can be mounted from vertical to horizontal.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Can
anyone give a recommendation for a minimum mounting angle of a raintite box?
Ideally 90 degrees, but in this case I may be forced to mount it at the same
angle as the panels – about 25 degrees, mounted off the roof about 6 inches. I
don’t think there is any reference in the NEC to this. It will be off the roof
about 6 inches in a mild climate, where they only get about 20 inches of snow a
year. Thanks.<o:p></o:p></span></p>
