Wrenches:
I use WEEB for Enphase, WEEB lugs and jumpers for the rails, and WEEB for
modules, except with SunPower, which uses the GBL-4DBT. If the lug isn't
bolted
on, it probably isn't bonded.
The problem here is UL, not WEEB. I do not share Augusts concerns.
I still feel that the module manufacturers should be responsible for
resolving the grounding and wire management issues. However, I am not holding
my breath.

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.
