[RE-wrenches] Rooftop wiring methods between multiple subarrays

[Max Balchowsky]

If your talking about conduit runs between arrays, we've always used minerallac clamps to attach to either the riser, or the frame, depending on the tilt angle and accessibility. The inspector has always accepted this as bonding between arrays.....

How about using a water pipe clamps on the
EMT.  A bare copper, # 6 or larger, should be able to be run outside
the conduit, as it is a bond between sub arrays.  My reading is
that, from the combiner box on,  an equipment grounding conductor
would need to be inside the conduit.
