Lets go ahead and get something started about dust collectors.
In a one man shop where you have a 1.5 HP dust collector with 4" and 2" PVC lines going to a 4" PVC main header, is it necessary to ground the PVC lines?
Jeez, the first question you ask has to be one of the most controversial. Any particulate flowing through a non-conductive duct will create a static charge. This charge may become strong enough to cause a discharge. The discharge can give you a nasty shock. This may be a good enough reason to ground the ductwork. The best method I've seen is to drive conductive screws into the duct from the outside about every 6" - 8" and connect to a grounded copper wire (14 ga or heavier). The screws do not have to penetrate into the interior of the duct, but should pass completely through the PVC.
