<DIV><FONT size=2 face=Arial>Regarding the DC disconnect, the 2008 Handbook
690.14C(1) comments, "These requirements generally prohibit long runs of PV
source and input circuits inside a building before reaching the required PV
disconnect. A short conductor run through a wall at the point of first
penetration to reach a disconnect mounted inside the building is allowed." I
think an inspector could bump a long DC circuit through a building even if it
was in conduit. What do you all think?</FONT></DIV>

readily accessible disconnect at the inverter is all that is necessary
according to the code. There may be practical reasons for additional
disconnects, but if the system has no combiner box, or the combiner is at the
inverter, only the disconnect at the inverter is
required.<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN

a lot of concrete and asphalt, we are forced to run our PV source circuits in
through one exterior wall, through a crawl space and out through the opposite
exterior wall to our inverter and disconnect. We will be using EMT and
will not be making any stops while inside the building. We will however
need to place a couple of pull-boxes due the various required bends in excess
of 360*. Will we be required to place a DC disconnect at the “first
readily accessible” point inside the building?<o:p></o:p></SPAN></P>
