I love the dust collector explosion deniers… because of the 99.9% argument. I purchased a three-prong plug at the local home improvement center and connected the grounding system directly to the ground lug (leaving the other conductors un-touched and insulated). This doesn’t make the ground “better”, rather just increases redundancy. This grounds the system at the center point. To my Jet Air Filtration unit on the ceiling.Each tool has a grounding lug on it, and should be connected to the grounding system of the dust collection system. ![]() To the metal from of the permanently connected tools.There is a screw on the inlet pipe that is the perfect place to attach to. My dust collectors frame (as all should be) is connected to the same ground as the A/C outlet and the machine’s motor. To the physical metal from of the dust collector itself.In The Geek Pub shop, I elected to connect my grounding system to physical ground at numerous locations: This is something that wasn’t covered in the video or article, but of course the best grounding solution in the world is of no value if it isn’t actually connected to ground! The most common piece of feedback or line of questioning I got on the previous article was around actual connection of the system to a physical source of grounding. Grounding Dust Collection Connecting the Dust Collection System to Physical Ground This provides a grounding mechanism for both the inside and outside air. In addition, blast gates are grounded by connecting a grounding lug to one the gates screws, or a dedicated grounding terminal if one is provided on the blast gate. At approximately every 48 inches the wire was terminated to a grounding lug via a 3/4 inch screw that penetrated to the interior of the PVC pipe. In The Geek Pub dust collection system, we wrapped the PVC pipe with braided copper ground wire kit. Many recommend running the wire on the inside of the pipe, or both wrapping the pipe and including a conductor in the center. Grounding of insulated material such as glass, plastic, or PVC is accomplished by wrapping the pipe with a braided copper wire and attaching it an various points. In fact, if you were to choose a dust collection ducting of the metal variety (such as tin, steel, or aluminum), then grounding would already be inherent in the system simply by its basic composition as long as something is connected to the system that bridges it to ground, such as being connected to the dust collector at one end, or a metal table saw at the other end. The basic premise of grounding the system is to keep the air and PVC in constant contact with a ground. It’s a good recap, especially if you’ve not yet seen the video on installing the PVC grounded dust collection system at The Geek Pub shop. Let’s recap the basics of installing and grounding dust collection before we go on. ![]() That’s what we’re going to discuss today. However, we didn’t really go into the grounding of the system to an actual ground source. Not something you want in your shop!ĭuring the course of the article and video we talked about the importance of grounding, and how the grounding system for PVC works. With the right combination of materials and and oxygen levels, this can cause a dust fire or an explosion to occur. ![]() ![]() This static can build up to the point where it arcs to ground unexpectedly. The same thing is happening in your dust collection system, on a much larger scale. Think about combing your hair with a plastic brush. PVC is very prone to generating a static charge when air is moving along the inside of it, along with charged particles of wood and other debris. In this article and video we installed a PVC “grounded” dust collection system into the shop. In a recent article and video publication we discussed installing an Automated Dust Collection System.
