Lumeta dealer has been sending links for unlisted wire management systems, nothing from Lumeta itself. Cooper B-Line EnviroShield is listed and is an easier drop in raceway but very expensive.<br><br><div class="gmail_quote">

[RE-wrenches] 690.31(B) "within the photovoltaic array"<br></font><br></div><div><div></div><div class="h5">
<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,
