<DIV><FONT face=Arial>Drake- on the tracker installs
we've done, the method you describe is standard procedure. the exception is that
on our very first we used RMC wrapped in a continuous layer of
anti-corrosion tape to keep the wet concrete from attacking the zink coating.
</FONT></DIV>
<DIV><FONT face=Arial>On all jobs since then we have used only rigid NM stubbed
up to just inches above the surface of the finished pier. Then we transisitioned
to EMT, offset and bolted firmly to the steel pipes. </FONT></DIV>
<DIV><FONT face=Arial>This process has passed muster when buried conduit
penetrated a concrete foundation into the new equipment room. A exterior
pier should be no different from a concrete foundation. Most any commercial
electrical contractor in your area should be able to detail the process that
works in that jurisdiction.</FONT></DIV>

<DIV style="FONT: 10pt arial"><B>Subject:</B> [RE-wrenches] Pole Mount
PVC</DIV>
<DIV><BR></DIV>Hello Wrenches,<BR><BR>With pole mount systems, It looks
cleaner and is safer to run the PVC conduit down the pole into the concrete,
and use a 90 degree elbow to come out through the side of the anchor
underground. This way, the pipe is protected from mechanical damage, and
there is nothing to trip over when adjusting the array for seasonal
tilt. <BR><BR>I was told that some building departments will not allow
this. Has anyone had a problem with using this method, either technical
or legal? How do you like to route your conduits?<BR><BR>Thank
you,<BR><BR>Drake <BR><X-SIGSEP>
