If I ground my PVC dust collection ducts to my water pipes, will I
need to sweat bigger copper tubing since my dust collector is 240V?

Is the copper used in the plumbing domestic or imported?

It's a 3HP motor, but not that efficient so I'll run it on a 60A
breaker. I'm planning to get about 9,300 CFM, but will use 18-inch
duct to make sure the pressure drop isn't too bad.

A good idea! This stuff should work:

I don't want SWMBO to get shocked while she's brushing her teeth.

Just don't let her use a WaterPik unless it's isolated.
