[RE-wrenches] 2011 NEC and impact in the field
Hi All - My shiny new copy of the 2011 NEC handbook just came in the mail and I've started reading through it trying to decipher what changes we should be expecting in the future. Although California is now just adopting the 2008 NEC which I'm quite familiar with, many jurisdictions will honor the newer version of the code if we provide a good argument for them. That said, does anyone who's checked out the new code have any interesting comments or advice on changes that might affect us out in the field? Section 690.31(E) is interesting in that it has quite a few detailed requirements for running DC circuits inside the building. Now it looks like MC cable is acceptable but that there are many more strict requirements about how the conduit or cable must be run. Labeling the DC conduit and J-boxes is also going to be a change we'll have to get used to. Hopefully there will be new reasonably priced label sources available. I'm sure I'm not alone in saying that it's always been hard to find cost effective labels which can hold up through the elements. The grounding section also looks substantially updated. As always, fun new things coming our way.

Re: [RE-wrenches] 2011 NEC and impact in the field
August, We're currently working on a SolarPro article on this topic. It will appear in SP4.3 (April/May 2011). As usual, there are a fair number of changes that impact PV installations. Our authors have done a good job, in my estimation, of pointing these out, discussing the implications, providing the reasoning behind the major changes. Should be a good introduction overview of the Code changes that impact PV installers. Also, starting with the 2011 NEC, Mike Holt is addressing Articles 690 705 as part of his Understanding NEC series. Look for his title, Understanding NEC Requirements for Photovoltaic Systems. Looking forward to getting my hands on a copy, David Brearley, Senior Technical Editor SolarPro magazine NABCEP Certified PV Installer david.brear...@solarprofessional.com Direct: 541.261.6545 On 1/13/11 10:35 AM, August Goers aug...@luminalt.com wrote: Hi All - My shiny new copy of the 2011 NEC handbook just came in the mail and I've started reading through it trying to decipher what changes we should be expecting in the future.

Re: [RE-wrenches] 2011 NEC and impact in the field
August; There was a webinar from Solar ABCs in autumn 2010 that covered many of these new 2011 NEC issues in detail, in a very practical way for the professional PV installer. I believe you can download the whole thing from them right now after the fact. I'm quite involved in teaching the PV / firefighter safety curriculum now, and signage is a big issue. In short-- engraved plastic signs are fine indoors or out, but don't penetrate an outdoor-rated box screwing them on! Stick-on vinyl signs need to meet UL 969. The webinar has some great photos of faded vinyl signs that have become unreadable.

I got my soft copy of NEC2011 at my electrical supply house for much cheaper than retail, and it came with a code to download the PDF version from online.
