Just installed a cyclone with complete ducting system. Not grounded.

Google it and you will see the chances of explosion are almost impossible in a home shop.

Do the research for your own satisfaction.

I use a ground on my dust collector. I have 4” plastic pipe and I run the wire inside the pipe back to the machine chassis for the ground.

I’ve had my d.c. and setup for about 15 years….It’s been in 2 different shops, and never been grounded. I use S-40 thin wall 4”, and never had a problem with it. You really don’t need to ground the plastic pipe. As far as I know, and have read, that there has never been a fire reported for using this pipe. I’ve never
heard an LJ on this forum report that they have had a fire using plastic pipeing, and most on here say they
don’t ground theirs either…..And I’ve never been shocked touching my machines, either..That’s what 3way
plugs are for…...To ground or not to ground, it’s up to you…...

This comes up every so often … I’m not sure there is a great fire danger, but if you are using any electronic devices (computer, radio, TV, MP3 player, etc.) that little static shock that you get when a system is not grounded can be deadly.

Electro-Static Discharge (ESD) is bad mojo for just about any electronic device that uses integrated circuitry (which is just about all of them).

I have a Clearvue cyclone with ungrounded PVC pipe. The only issue I ever had was a ticking sound where the spiral pipe had a small gap (1/16”) between the wire and the frame of my bandsaw. I bent the wire so it touches the frame. Now that section of spiral pipe is grounded and does not spark. I planned to ground all of the spiral pipe wires to earth ground, but none of the other locations bother me.

The only places that you may have issues is where you touch the pipes. Most of my PVC pipe is up near the ceiling. The only parts I touch are the blast gates and I can always ground them to the machine chassis if needed.

btw: I am in California where the humidity probably ranges from 20-30% most of the time. More humid locations should have even less issues. Arizona at 8% humidity might be slightly worse.

Only reason I ground my PVC is for my own comfort, it keeps me from getting the bejezzes shocked out of me.

Thanks for the info. I think I’ll skip the grounding since I live in Houston and this is about as humid as it gets and I still manage to survive the inhumane heat.

the proper word is bonding, not grounding. look in the national electrical code about bonding {GROUNDING} of in areas with flammable dust. #12 copper wire is cheap compared to what could happed from a spark in the wrong place. pry a couple of dollars out of your pocket and be safe.

Being that plastic is a non conductive substance, you are not grounding the pipe. The wire that you would “so call ground” the pipe is only there to give a pathway for the build up of static electricity to discharge. Although it is a nasty jolt, in a small shop I don’t believe there’s a record of anyone having an explosion from dust.

when I got my set of flexible 4” hoses used – it had ground wire inside. the only thing it really did was clog the pipes with shavings that would get stuck in the wire.

I now do not have any ‘grounding’ (not really grounding as was already mentioned) running PVC duct from my Jet1100 – no static, no problems, no clogs.

I did a lot of internet reading before I installed my PVC ductwork (8” mains, 6” secondaries, and 4” branch connectors) under the floor of my shop and the writer that seemed the best informed to me was this one: http://home.comcast.net/~rodec/woodworking/articles/DC_myths.html I have had my system up and running for five years and never had reason to question his conclusions. He does say that the greatest danger with PVC is personal shocks. I don’t get them because my ducting is mostly under the floor. I do have an 8” vertical PVC pipe that comes straight up out of the floor to the input of my DC (5 Hp Craftex cyclone) but I’ve never even gotten a shock from it. That may or may not be because it’s wrapped with foil. Read the article. The guy knows his stuff.

I was running an ungrounded dust collection system until day I was wearing shorts and walked past the flex hose and got a good zap – at that point I had a flash back from my childhood and an electric fence – it’s now grounded.

I don’t think my home setup generates enough juice to start a fire but it’s enough to wake you up!

@CessnalPilotBarry: I would be really hesitant to add humidity to my shop [via a humidifier]. What happens after you build a piece and take it out of an environment that you pump moister into the air? Care to guess?
