Hi Mark, The current issue of IAEI magazine has an article writing by Bill Brooks called "Hot Topics for PV System Installations." In the article, he directly addresses 2014 NEC 690.47(D).
Unfortunately I don't see this article posted online, but you might want to check it out if you can find it. My understanding is that the intent of 690.47(D) is to require an additional electrode when PV is installed on structures that don't already have and electrode system such as a separate building, garage, etc. August -----Original Message----- From: RE-wrenches [mailto:[email protected]] On Behalf Of [email protected] Sent: Monday, January 30, 2017 10:24 AM To: [email protected] Subject: [RE-wrenches] 690.47(D) Folks, NEC 2014 is in effect in California. I just pulled a permit for a residential system and it had a little stamp that had 690.47(D) circled as a requirement. Anyone worked with AHJ's in California who are now requiring this? I am planning to not install the electrode, siting Exception 2 and trying to say that the existing electrode next to the build is "next to the array"?
