<DIV>This seem ridiculous to me..... the idea that an inspector is having you
ground a hot water collector is akin to requiring a pressure relief valve on a
pv module. Or am I missing something here? Ask the manufacturer of
the hot water panel where in the UL listed connection point for the
bonding point is. If required (oh the horror) then there will be
one. They manu will most likely just laugh or say "wha?" In any case, the
plumbing (copper?), unless isolated from the household by di-electrics, is
grounded quite nicely and can serve as your 'ground' path.</DIV>

<BR>> We have a local<BR>> electrical inspector who insists that
hot<BR>> water collectors be grounded, regardless of roof type. I<BR>>
have received<BR>> exemptions from this individual before by documenting
that<BR>> it would void the<BR>> collector warranty by putting a hole in
the collector to<BR>> mount a ground lug, but<BR>> this person is
persistent and doesn\u2019t really accept<BR>> the explanation.<BR>> Anyone
have hassles / solutions with OEM\u2019s or<BR>> inspectors with this?<BR>>
