<DIV><SPAN class=515124919-06092011><FONT color=#0000ff size=2 face=Arial>So the
issue is one of physical protection of the conductors. That is what tha AJH
should be looking to. If he has cold feet about approving a non-standard method
using un-listed componets based on local conditions, then he is
understandably going to ask for a solution utilizing listed materials and
standard methods.</FONT></SPAN></DIV>

[RE-wrenches] 690.31(B) "within the photovoltaic array"<BR></FONT><BR></DIV>
<DIV></DIV>Wrenches,<BR><BR>I am installing Lumeta peel and stick modules
(similar to laminates) on a flat EPDM roof. No racking. NEC2008 690.31(B) says
single conductor cable listed and labeled as PV wire shall be permitted in
exposed outdoor locations..."within the array". 690.2 defines array as a
mechanically integrated assembly of modules or panels within a support
structure...to form a direct-current power producing unit. With the Lumeta's
there is no support structure. If you look at the diagram in the NEC 2008 (page
70-576) it shows a box around the modules or panels and labels that box as the
"Array or photovoltaic power source". <BR><BR>My AHJ was at first not sure but
then told me I had to install all the PV wire in a listed raceway because the
interconnects between the Lumeta's were not within the array. But if you draw a
box around all the Lumeta's it would look like the array diagram that I referred
to above.<BR><BR>Because of my roof layout, it would be much easier to install
an unlisted wire management system within the array rather than conduit which I
will do but in reading the NEC it just wasn't clear to me what "within the
array" means.<BR><BR clear=all>Any thoughts would be appreciated.<BR><BR>Thank
you.<BR><BR>Larry Liesner<BR>Design and Installations<BR>Elektron Solar,
