that was the intention necessarily, but I have argued the same thing with
varying degrees of success. Fortunately (?) we are still on 2011 here, but 2014
is coming and hopefully AHJs will remain permissive of no additional electrode
if the home already has one within 6 feet of the service entrance (which it
almost always does).<o:p></o:p></span></p>

For micro-inverter systems I have successfully argued the application of<br>
Exception No. 1. in that the load is the micro-inverter.<br>

<p class=MsoNormal style='margin-bottom:12.0pt'>Folks,<br>
<br>
NEC 2014 is in effect in California. I just pulled a permit for a<br>
residential system and it had a little stamp that had 690.47(D) circled as<br>
a requirement.<br>
<br>
Anyone worked with AHJ's in California who are now requiring this? I am<br>
planning to not install the electrode, siting Exception 2 and trying to<br>
say that the existing electrode next to the build is "next to the
array"?<br>
<br>
