<div dir="ltr" align="left"><span class="468365813-14092010"><font color="#0000ff" face="Arial" size="2">I believe the AC GEC runs from; the point where the ungrounded
current carrying conductor is bonded to the enclosure of the service enterance
equipment; to the connection to the ground electrode system. Conductors that run
from the service enterance equipment, thru the premis to the Enphase are bonding
jumpers that are not required to be continuous.</font></span></div>

inverters<br></font><br></div>
<div></div>Friends:<br><br>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?<br><br>Also, non-reversible splices need to be listed for
use in grounding systems. Any suggestions on make and model of splices so
listed?<br><br>Any advise from those more experienced is much
appreciated.<br><br>William Miller<br><br>
