color:#1F497D'>I assumed you were interested primarily in (A) William. We are
using a screening method on DPW TPM that works well for us. We are using an
outdoor plastic lattice, white in color, that we buy at Lowes and custom cut
for our specific needs. We use it to screen any MC cables that are within 8
feet of ground level. I could send anyone interested a picture if they e-mail
and request. To bring our wiring down from the PV modules we enter the DPW gimbal
thru a Hubbell ¾” 90 degree cord grip (DPW has a knock out for such) and
then we exit the steel pipe mast directly into the back of a PVC j-box thru a
2-1/2” hole we make in the pipe, we weld a 6x6 plate onto the hole for
the j-box and protect the wiring coming out of the pipe mast with a short piece
of PVC that is bushed on both ends. After the j-box we are all SCHD 80 PVC before
transitioning to schedule 40 under ground.<o:p></o:p></span></p>

I have not received my 2008 NEC on CD. Pending it's arrival, could one of
you good folks please post 690.31 to the wrenches as a personal favor to me?<br>
<br>
Thanks in advance.<br>
