I have 6" PVC ductwork going to my ClearVue Cyclone. Recently, but only when using my DeWalt Planer, have I been getting a shock. I am using the Rockler expandable 4" hose for my jumper. So i am not sure if it is the Rockler hose or my system. If I take of DC it does not shock. Since I never set up grounding on my initial install, that jhas got me to thinking I should regardless of the source of the shock. It is a mild static electricity sort of shock.
Any suggestions on how to ground a PVC system?
