Re: [RE-wrenches] Grounding Separately Derived AC System

I agree and read it the same way. Not a separately derived system. Jesse Sent from my iPhone On Jan 23, 2012, at 7:13 PM, "Dave Palumbo" wrote: > Regarding NEC Article 250.30 does Informational Note #1 mean that a standard > (no battery) grid-tied PV system is not a Separately Derived Syst

Re: [RE-wrenches] Grounding Separately Derived AC System

I agree, no bonding jumper from neutral to ground in a grid tied system disconnect. It's not a Separately derived system by NEC definition. The premises does have grid power and pv power, but they are from the same system. That's how I see it. -- Alex Cozine NABCEP Certified Solar PV Installe

That's always been my interpretation as well, reinforced at seminars with John Wiles and Bill Brooks. Ray Walters On 1/23/2012 6:13 PM, Dave Palumbo wrote: Regarding NEC Article 250.30 Informational Note #1 // // My interpretation is that a standard net-metered PV system is therefore not a

Re: [RE-wrenches] Grounding Separately Derived AC System

Regarding NEC Article 250.30 does Informational Note #1 mean that a standard (no battery) grid-tied PV system is not a Separately Derived System? I'm primarily interested on the consensus view of Bonding the Neutral (grounded conductor) to Equipment Ground in a 60 Amp Fused Disconnect located b
