William,
Here's a link to listed splices made by Burndy, and compared to exothermic welding. http://portal.fciconnect.com/res/en/pdffiles/brochures/Quick_Ref_Guide.pdf Kirk Herander Vermont Solar Engineering 802.863.1202 NABCEP(tm) Certified Solar Installer NYSERDA-eligible Installer VT Solar Incentive Program Partner _____ From: [email protected] [mailto:[email protected]] On Behalf Of William Miller Sent: Tuesday, September 14, 2010 12:46 AM To: RE-wrenches Subject: [RE-wrenches] GEC for Enphase inverters Friends: According to the 2005 NEC 250.64(C), the GEC for an AC system needs to be continuous without splices unless they are irreversible. I am not clear where this conductor starts and ends. Is it from the ground buss in a sub-panel to the disconnect switch on the roof, or to each inverter? Also, non-reversible splices need to be listed for use in grounding systems. Any suggestions on make and model of splices so listed? Any advise from those more experienced is much appreciated.
