Folks, PVC is an insulator. You CAN NOT GROUND an insulator. If you
could, you would not be reading this message because none of our
computers (or anything else electronic) would be working.

Repeat after me:

"I cannot ground PVC"
"I cannot ground PVC"
"I cannot ground PVC"
"I cannot ground PVC"
"I cannot ground PVC"
"I cannot ground PVC"
"I cannot ground PVC"
"I cannot ground PVC"
.....

Yes, PVC is more a dielectric. That said, one puts wire through the
ducts so that it "collects" the charge that is generated by the movement
of the air/wood through the duct. You ground the wire to dissipate the
"static charge".

So while PVC doesn't "conduct", it can generate "Static electricity"
under the right circumstances. That is what you're collecting and
grounding.
