[RE-wrenches] 2014 NEC 705-100 (A)

[billbrooks7 at sbcglobal.net]

Jay,
 
You need to provide more information. The 2014 NEC is a significant improvement in the language related to single-phase inverters on a 3-phase service. To read it any other way shows a very large misunderstanding of the language.

It should be much better on the 2014 NEC, not worse. Where do they not get it. The old language was used routinely to prevent single-phase inverters on the 3-phase systems. I wrote the change to the 2014 that greatly improves the language.

Bill.

HI All,

I’ve got a client who’s having some issues with the building department. (for the 705-11-A  NEC 2014) Now it is true that we in California are now in 2014 NEC) They are saying that he isn’t allowed to install the 3rd  inverter onto a 3 phase service ( this system was done in stages, using SMA 3kw for phases 1 and 2) Now they are being stopped on adding the 3rd.

Anyone ever run into this before?
Any answers?

thanks

jay
