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?
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.
I don't want SWMBO to get shocked while she's brushing her teeth.
Hope this helps, John
