Dust Extraction using PVC DP - Grounding required or Not

Hi All,

 

My current dust collector (DC) setup is flexible 100mm hose from DC to the tool be it table saw, jointer, thicknesser etc.

I am considering to run 100 PVC DP around the garage and drop points to every tool.

 

Any suggestions, has any one done this in their workshop, do you have to ground to the earth?

Or, would just copper grounding wire kit that one can get on Amazon be sufficient by wrapping the wire around with DP .

 

Regards.

People will argue that you need 150mm ducting for the fine dust and an extractor capable of running it. Not many machines are set up with the ports either so they need to be modified as well.

 

In an ideal world you would avoid t-pieces and elbows as they restrict the flow, the real world you try to minimise the number you have and 45 deg take off tees do less damage than 90 deg ones.

 

Dave of blue t-shirt fame has done a video on installing earth wire and how his system is grounded.

Thanks Brand 👍🏻

I did come across Dave Stanton video and in fact my question  “if ground to the earth” was a necessity was based on that. 
Also seen what Wayne did (in this forum) which I think does not require grounding... that kit alone is $400 bucks.

In my case the grounding rod is not near any of my sheds so I would go to the carport post as I think we over engineered them into the ground.
