Clear Plastic dust collection pipe & grounding

Ok, got one of those Whole Woodshop Dust Collection Systems with 30 feet of 2 1/2 inch clear plastic pipe and the connectors , blast gates, etc. ; but I can't figure out if the dang pipe needs to be grounded with copper wire. If it does, do I have to run copper wire through ALL 30 feet of the pipes ???

You want the entire length grounded so that it does not build up static charge.

yes run a wire through it , you can build up enough static with all that air that you can cook the electronics on some of the new equipment

Just a bare copper 12 gauge wire?

Yes. Wire must be bare.

I have worked in an engineered lumber mill for the last 20+ years. Anywhere nonmetallic dust collection hose is used we spiral wrap a bare copper ground around the dust pipe and bond to ground. It doesn’t have to be #12 it could be #18 or 20. Make sure to bond all metal fittings in the run as well t’s el’s etc.
