Matt, et. al:

This is a high-voltage, low-amperage system--unfortunately.

Tomorrow, we are "correcting" all of the other "issues" the inspector noted,
and awaiting responses from Grundfos and a Washington State Grundfos
distributor (with not much hope of resolution).

Hmmm.  Installing a "standard AC" pump for the inspection . . .  Do you mean
an AC pump and inverter with UL listing?  How does this make sense with a DC
solar array and no inverter?  The inspector is savvy enough to see through
this ruse.

I will keep you wrenches posted, but I think this will be a disaster for us
and our client unless the inspector, by some miracle, changes his mind and
accepts the CE rating in the Grundfos literature.
