My inspector is calling me because I used the upper section of my PSR
battery cabinet to run my PV source circuit, battery circuit, and my ac
circuits. I believe that the wires are permitted in the same
UL1741-2000 listed enclosure if the wire insulation ratings are equal
to or greater thanthe maximum circuit voltage applied to any conductor
within the enclosure (NEC 300-3). there is an exception (NEC 690-4 (b))
for PV input and output circuits, but still allowed if seperated with a
partition or are connected together. Does wire ties meet this
requirement?. I will need to make a second penetration into a stucco
strawbale wall to make the inspector happy...seems rather extreme. Any
experience with this situation out there? Thanks!
