Could you maybe add some details to the photo and download it to the Wrenches ftp site? Then we can all view it there.
I don't recall the process though Michael once posted the steps. The site is a great place for info just like this. M also screens everything before it gets posted. ftp://ftp.re-wrenches.org/pub/ Jim Duncan North Texas Renewable Energy Inc www.ntrei.com <http://www.ntrei.com/> NABCEP PV 031310-57 TECL-27398 nt...@1scom.net 817.917.0527 NABCEP Logo From: re-wrenches-boun...@lists.re-wrenches.org [mailto:re-wrenches-boun...@lists.re-wrenches.org] On Behalf Of August Goers Sent: Wednesday, February 20, 2013 2:34 PM To: RE-wrenches Subject: Re: [RE-wrenches] Redundant Bonding Hi Karl - I'll send you a picture off list showing how we typically wire up 7-terminal meter sockets. In the Milbank meter sockets we typically use the neutral bar is factory bonded to the can. So, we pass the neutral through the can and then connect a ground in the can. This provides the power necessary to run the meter without bonding the neutral to ground in two locations. I'm not sure that I'm following your issue relating to the inverter and NEC 250.142(B). The Power One 10k unit has HF isolation and still needs a DC GEC as far as I know.

The system consists of a PVI 10.0, 3-phase inverter to be interconnected via backfed breaker to a 120/208 service. We have a feed in tariff program which requires a solar generation meter base. The solar meter base is provided by the utility, it is 7-terminal therefore it has a neutral connection and a bond between neutral and ground. The service is also bonded, of course. We have two bonds resulting in a ground loop. The utility refuses to allow us to remove the bonding jumper in the solar meter base and we can't float the neutral thru because the meter must see a neutral to spin. The inverter has an isolated transformer which I believe steers us around 250.142 (B). However, Power One does not specify a GEC termination point in their inverter so the reviewer is reluctant to accept this solution. Has anyone ran into this issue? Any thoughts? Thank you for your help! Karl Jaeger <http://lightwavesolarelectric.com/> Description: FOR-EMAIL-SIGNATURE (Small)
