I suspect that concrete would have similar effects. In New Mexico, state Code requires Schedule 80 if PVC is used above grade, I suspect primarily because of the intensity of our high-elevation sun, so by that logic you'd use a Sch. 80 90 sweep to exit the slab, then transition.<br>Allan</span></p><div><div><p class="MsoNormal" style="margin-bottom:12.0pt;background:white"><b><span style="color:black">Allan Sindelar</span></b><span style="color:black"><br></span><span style="font-size:10.0pt;color:black"><a href="javascript:_e(%7B%7D,'cvml','allan@sindelarsolar.com');" target="_blank">allan@sindelarsolar.com</a></span><span style="color:black"><br></span><span style="font-size:10.0pt;color:black">NABCEP Certified PV Installation Professional<br>NABCEP Certified Technical Sales Professional<br>New Mexico EE98J Journeyman Electrician<br>Founder (Retired), Positive Energy, Inc.<br><b>505 780-2738 cell</b></span><span style="color:black"></span></p><p class="MsoNormal" style="background:white"><span style="color:black"> </span></p></div></div><div><p class="MsoNormal" style="background:white"><span style="color:black">On 10/29/2016 6:50 PM, AE Solar wrote:</span></p></div><blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"><div><p class="MsoNormal" style="background:white"><span style="color:black">Wrenches, </span></p><div><p class="MsoNormal" style="background:white"><span style="color:black">I have a project where the DC run is going through the wall system of the house, down through the slab, out the building underground and into another building.
