[RE-wrenches] GEC for Enphase inverters

[Mark Frye]

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.

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.
