If the gutter can extend under the service panel it works even better (out the back of the gutter into the wall and up into the service panel) If you want pictures, e-mail me direct.......<br><div> </div><span style="font-family: tahoma,new york,times,serif;">Max Balchowsky</span><br style="font-family: tahoma,new york,times,serif;"><span style="font-family: tahoma,new york,times,serif;">Design Engineer</span><br style="font-family: tahoma,new york,times,serif;"><span

Kirk,<br><br>Just zip tie your DC stuff together and your AC stuff together and keep the<br>two bundles separate. Then they can be in the same trough. At least that's<br>the way we do it. I don't know about in the same conduit, I'd guess no. <br><br>Conrad<br>Cotuit Solar<br><br>-----Original Message-----<br>From: <a ymailto="mailto:re-wrenches-bounces@lists.re-wrenches.org" href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a><br>[mailto:<a ymailto="mailto:re-wrenches-bounces@lists.re-wrenches.org" href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a>] On Behalf Of Kirk<br>Herander, VSE<br>Sent: Saturday, April 09, 2011 9:29 PM<br>To: <a ymailto="mailto:kirk@vtsolar.com" href="mailto:kirk@vtsolar.com">kirk@vtsolar.com</a>; 'RE-wrenches'<br>Subject: Re: [RE-wrenches] 690.4 (B) ???<br><br>PS Does this merely mean that conductors from more than
