DC Arc-Fault Protection

Is this being enforced in your neighborhood?

Not yet, because the 2013 California Electric Code, which is essentially the 2011 NEC, doesn't go into force until January.
Fortunately the products are on the shelves to deal with it, at least from SMA and Fronius.

We're getting pushback from an inspector on an install that had the permit approved two days prior to the Fronius press release at the end of May.
He now wants the new Fronius IG+ Advanced inverter installed.

 

[jaggedben]

Well, that's just lame of him, IMHO. I gather you've already tried to invoke 90.4.

 

[c_picard]

Yup, 90.4 indeed.

Unfortunately, the word "may" is in there.

Seems like the dam has burst. We are seeing this enforced in various jurisdictions nation-wide. Some AHJ's are going as far as not honoring legacy permits.
It's for the best, from a safety perspective. Inverter mfg's have a lot of back-stock inventory to work through.
