   Run a bare copper wire through the inside of the hose and ground it on the case of the DC.  Also make sure the DC is connected to ground via the 3 prong plug.  #14 solid copper wire would be sufficient.

   Thank you for the advice. I will install the copper wire and ground it to the unit.  I am running the DC on 240 so it is ground via the plug.

   JGI,

   This rates close to an urban myths about static charge from PVC pipe causing wood dust explosions or fire within the dust bags/bins.  Fire is far more likely from a spark caused by a piece of metal striking the impeller than it is from static discharge.  The downside to the static is that it will cause dust to be attracted to the outside of the DC dust work.  This can be alleviated by grounding the ductwork by making very modest turns of copper wire around all of the duct work and attaching it to an external ground.
