can speaker wire be used for the grounding wire for the dust hose?

I think that you would find it interesting to search this site for grounding of dust collection systems. The necessity and value of grounding them in PVC and hose systems has been debated.
You can use anything you want, because it won't do a bit of good.
(Was that too direct this early in the thread? )
Google "copper antenna wire" and be prepared for sticker shock! Mine is wrapped and run inside pipes, mainly to keep dust from collecting on outside of pipe.
Lets say it: You can't ground an insulator.
I've pointed this out before....the mythbusters could not make dust explode with a spark, so I'm not worried.

You guys take this too literally, both from the responses and from the OP. It's not "grounding", it is for static discharge and it does help. I don't know and haven't found the correct term, akin to calling a tissue a Kleenex.
I don't know about anyone else, but I managed to disconnect by wire the other night while doing some deep cleaning (move equipment to clean under, behind, and over). I didn't know it until I took a hit from the flex hose to the shoulder. I had to stop for a 1/2 hour while I regained the feeling in my left arm. The worst yet. Worse than any hit I've taken from 120V. The pipes have been up for 3 years plus it's so humid I'm running two dehumidifiers in the basement shop.
You can't ground an insulator and thus grounding at a specific point will only prevent a static charge at that specific point and a few mils around it. Period.

So much to learn, so little time.....
i didn't mean to start to debate, but thank you for all the input. I think I'll skip the wire since I havn't had an issue for the past year.
This akin to saying that a lightning rod won't work because your house is an insulator. I haven't seen any proof that PVC in a dust collection system can discharge static electricity in such a fashion to ignite wood dust, but I think everyone can agree that you can shock the foo out of yourself with the static buildup. Adding wire to bleed off that charge to ground may be a fine idea if you worry about zapping yourself. If everything is routed so you never come in contact, then I wouldn't worry about it.
There is no evidence that a home DC has exploded or caused a fired as a result of proper use.
Grounding PVC to eliminate static will only be effective at the point of contact and a few mils around it.
Lightning rods work because the metal used is more conductive than the house and the charge is directed there via ionized air which is more condictive than non-ionized air or your house.

It couldn't hurt, and for a few dollars more you'll have piece of mind. (Using bare copper wire is the easiest and cheapest.) Thats worth a couple dollars isn't it.
