Derek_PNW Posted January 27, 2017 Report Share Posted January 27, 2017 Well, if I had waited a few months to wise up I may not be in this situation. I thought I could buy a shop vac, cyclone, container, and some plywood to build a nice quiet dust collector. I should have just bought a dust collector... Well I saw many designs online and none had a lot of ventilation for the shop vac... I thought it would overheat and while it still works it blows my sad 15A breaker instantly (that is my next task.... power distribution...). I am thinking it has a short or something... maybe someone can explain a theory or two on why... The shop vac draws 11.8A. My dad 15A breaker in my garage also has one GFIC socket as well... so the breaker is not blowing but that is... Anyways to my main ask... the cyclone has a 4" pipe on the top. Any suggestions on mounting a dust collection blower from a craigslist dust collector? Any way to have it filter? I am open to all suggestions. Here is my "dust collector." Thanks all for the help!

freedhardwoods Posted January 27, 2017 Report Share Posted January 27, 2017 Are you saying that on one circuit it's tripping the breaker, but on another circuit it's tripping the GFCI? 1 Quote Link to comment Share on other sites More sharing options...
Jfitz Posted January 27, 2017 Report Share Posted January 27, 2017 yeah, what he said. I'm not sure what the exact breaker issue is... That's a really nice setup. If the only issue is that it's tripping the breaker - you need to fix the breaker issue. If the shop vac works, there's not really a reason it should trip a 15A breaker. Breakers do go bad........so you might want to try it in different circuits to see if it works elsewhere. To your question about mounting a blower - there are a lot of factors. would need to see what the blower looks like; the blower itself might dictate how to mount filters; also how much head room you have. I could see some vertical supports/legs mounted to your cart extending up, to a platform just at the top of the cyclone onto which you mount the blower. That assumes you'd leave the shop vac in the cart - and that you have the headroom for such a tall thing. It'd be pretty top heavy, so you might reconsider remaking your cart - take the vac out, put the drum in the cart and the cyclone on the top, and then the blower on top. If nothing else it'd be shorter. 1 Quote Link to comment Share on other sites More sharing options...
CandorLush Posted January 27, 2017 Report Share Posted January 27, 2017 I would be way more concerned about fixing the breaker issue than kicking yourself about going with "just" a shop vac. That setup should be working great for you. My first question is how sealed is the box? 1 Quote Link to comment Share on other sites More sharing options...
gee-dub Posted January 27, 2017 Report Share Posted January 27, 2017 Just a qualifier about your setup. I have something similar but, it is a shop vac, not a dust collector; set your expectations reasonably. I think you did a great job on it and simply have to resolve an electrical problem. Your build is much more refined than my "mad scientist lab prototype" that I have been meaning to rebuild. How old are the breakers; they do wear out. Do you have a VOM and have a fundamental familiarity with its use? Is there an outlet on another circuit you can run a properly sized extension cord to in order to eliminate the vac? Is there an air return properly sized for the vac's intake? 1 Quote Link to comment Share on other sites More sharing options...
Derek_PNW Posted January 27, 2017 Author Report Share Posted January 27, 2017 Thank you all for the support. To be honest, I was frustrated last night. I was trying to clean up the garage so I can finish my workbench and the damn thing would trip right when I turned it on. So I went to the next step... buy a real dust collector. Thanks for the help and I will get on answering your questions. After some internet research, I have one GFCI socket which is right after the breaker. The GFCI trips and the whole garage blacks out. Why is there one GFCI in the garage? Why wouldn't the circuit just rely on the breaker for protection? It is a great point to test it. I did some research and I will go pick up the necessary instruments. If the GFCI is bad I feel comfortable replacing it. I am a little more cautiously optimistic with the actual breaker. Now on to the shop vac cabinet. It is sealer except for the exhaust. I think I should install a few cabinet fans... I will also test the resistance of the shop vac since I did smell that lovely burnt electrical smell. Again thank you for all of the help! Sorry, I forgot to answer your question Gee-Dub. The town home was built in 2008 so I would assume the breakers have not been replaced yet. We bought it last year. Quote Link to comment Share on other sites More sharing options...

AceHoleInOne Posted January 27, 2017 Report Share Posted January 27, 2017 I have no electrical knowledge whatsoever. However, I had an air compressor that kept popping the breaker in my garage. I was using a long outdoor orange extension cord with the compressor. I went to a local guy who rebuilds electrical motors and he advised I shorten up the extension cord and use a more heavy duty cord (thicker). Solved my problem. -Ace- 1 Quote Link to comment Share on other sites More sharing options...
drzaius Posted January 27, 2017 Report Share Posted January 27, 2017 Your concept is good. I have a Ridgid vac & Dust Deputy that I use for small tools like the router & sanders. It performs very well & hardly any dust gets to the filter. Before I got a big dust collector that was all I had. It kept (barely) up to the jointer & planer. One small thing you could improve, is to replace the flex hose from the cyclone to the vac with hard pipe & elbows. Less static pressure loss. Lee Valley had a good selection of small pipe & fittings. Quote Link to comment Share on other sites More sharing options...
Popular Post wtnhighlander Posted January 27, 2017 Popular Post Report Share Posted January 27, 2017 GFCI is a different form of protection. It senses if there is more current going "out" on the hot wire, than coming "in" on the neutral. This indicates a "Ground Fault" (the GF part). Ground faults often mean the circuit is shorted to ground via the user's body, so the GFCI is designed to interrupt the circuit at fault current lower than required to kill you, measured in thousandths of an amp. Panel circuit breakers are designed to protect the circuit from overheating and catching fire. The sense only the current on the hot wire, and trip if it exceeds the rating on the label, typically 15 or 20 amps in a residential 120 volt circuit. 3 Quote Link to comment Share on other sites More sharing options...

freedhardwoods Posted January 27, 2017 Report Share Posted January 27, 2017 About 40 years ago I was using a handheld, metal case grinder. I stepped into some water on the shop floor and started getting shocked. It was enough juice that I couldn't let go of the grinder, but it didn't trip the breaker. Fortunately I had enough muscle control in my arm to throw the grinder out of my hand. A GFCI would have given me a little jolt and then tripped.

I don't know any more than what I was looking up awhile back when I was helping a neighbor troubleshoot his garage power, but I believe anything outside of a living area, including in garages and sheds needs protection. In the neighbors case, I guess it used to be ok to tie it into a bathroom GFCI so the outlets all looked normal but the GFCI was tripping in his basement bathroom so it took us forever to figure out.

That makes more sense. I believe someone did that in my families old house to put a plug on the back porch. Garage power is no different than the rest of the house. Even outdoor sheds often have power professionally ran to them buy tying in a breaker, running and burying conduit and running up to a light, or a plug or two. Of course, once you run power to a shed or put it on a foundation, the city\county often will try to tax it as part of the house sq footage jerks lol Quote Link to comment Share on other sites More sharing options...
Derek_PNW Posted January 27, 2017 Author Report Share Posted January 27, 2017 Possibly install a 240V outlet with some kind of big breaker and use on of these... any ideas? https://www.amazon.com/gp/aw/d/B000LEMTYU/ref=mp_s_a_1_2?ie=UTF8&qid=1485408074&sr=8-2&pi=AC_SX236_SY340_QL65&keywords=temporary+power+distribution&dpPl=1&dpID=415SI3WPmrL&ref=plSrch Quote Link to comment Share on other sites More sharing options...
bleedinblue Posted January 27, 2017 Report Share Posted January 27, 2017 I think for the price of that thing, you could easily hire an electrician to properly install all the outlets you'd need in your garage. 1 Quote Link to comment Share on other sites More sharing options...

They're not required in ceiling outlets used for garage door opener, but they are required for the wall outlets. GFCI is also required for outlets in unfinished basements as well. The basic assumption is if you've got a concrete floor, the chances are pretty good you're going to pour water on it. Anyway, back to the OP. The GFCI breakers can also go bad. I'd start by replacing that. A new GFCI costs about $10. Quote Link to comment Share on other sites More sharing options...

wtnhighlander Posted January 28, 2017 Report Share Posted January 28, 2017 If your vacuum is tripping the GFCI, the outlet is bad, or your vacuum has a problem that could kill you. Don't take shortcuts here. 1 Quote Link to comment Share on other sites More sharing options...

Elroy Skimms Posted January 30, 2017 Report Share Posted January 30, 2017 For a lot of GFCI installs, there is one GFCI and the rest of the outlets are downstream from it, so you essentially get GFCI protection on the entire line of outlets. It's cheaper than installing a GFCI on every outlet. But if you plug your vac into any outlet in the chain, you are still running it on the same GFCI, even if you aren't using the exact same outlet.

This is the best advice here. It could be just a bad GFCI, which is easy to replace. Or it could be that the vac is trying to kill you (or burn your house down). There is no harm in replacing the GFCI, they are easy to swap out and only a few bucks at the hardware store. But don't take it out and put a regular outlet in its place. If replacing the GFCI doesn't solve the problem, your shop vac might be trying to murder you and I would suggest repairing or replacing it. -E 1 Quote Link to comment Share on other sites More sharing options...

At first glance you'd think one of the bathrooms wasn't protected by GFCI at all. Quote Link to comment Share on other sites More sharing options...

I tried tracing the pipe from the panel out the outlets to see if the wire was disconnected somewhere. I finally gave up and hired an electrician, who did some detective work and found the outdoor outlets (which were not GFCI) were all connected our our powder room outlet (which was GFCI). We had never used that outlet for anything so didn't realize it had tripped, causing the outdoor outlets to not work. All of the houses in my subdivision were wired that way. We ended up running new pipe to my panel, so the outdoor outlets would be on their own breaker, and installed new GFCI outlets. Quote Link to comment Share on other sites More sharing options...
Derek_PNW Posted February 3, 2017 Author Report Share Posted February 3, 2017 To jump back into the conversation. . . First, thank you again for all of the help and insight. Electricity is a big unknown for me and dust collection is too. I am sure I overthink CFMs and obviously have a high expectation for machines which were not designed to fit my requirements. . . I trashed my shop-vac last night. On a "cold start" it pulls a high static pressure. After a few minutes of use, the motor starts to heat up, falters, and the suction drops significantly. Plus there is a strong burning electrical smell. The good news, it was $50 on Black Friday (Black Month more like it). The bad news, I am out $50. I have recently purchased a Grizzly G0710 1HP wall-mounted dust collection blower with the optional canister filter (the joys of living in Washington about a hour away from their showroom). Are you ready for my excellent "Sketch Up" skills (P.S I used PowerPoint instead. . .)? I am planning to place the blower into the cabinet with fans on the back of the cabinet on the top and bottom to cool the cabinet. The dual fans move 107CFM each. . . so I think it will keep cold air in and hot air out easily. For the inlet connection to the blower, I would like to use a small segment of 4" flex hose and then transition to 4" PVC up to the cyclone (see the side view). Will the 4" flex hose dramatically kill my CFM if used for about 6" in length? For the outlet to the canister filter attached to the side of the cabinet, I will use 5" flex hose. Will the outlet flex hose run hurt CFM as well? Should I use PVC? Final question, anyone know where to buy smooth bore flex hose? I know it is not extremely smooth in there, but I am also worried about how I attach it to the tool I am using. I will move the hose to the tool I am using. Any thoughts and ideas are very much welcomed! Thanks! Quote Link to comment Share on other sites More sharing options...

Sorry, I forgot to answer your question Gee-Dub. The town home was built in 2008 so I would assume the breakers have not been replaced yet. We bought it last year. Sounds like all the other receptacles are down line from that one GFCI receptacle. One way to make all the receptacles on a circuit GFCI is to control them all from the first one. It's been the cheapest way to do it from the beginning of such circuits, but when they first came out with the GFCI receptacles, they were a pretty unreliable lot. I always used a GFCI breaker controlling regular receptacles. The simplest fix will be to replace that one receptacle, but read the instructions on, or in, the box to wire it to control the other receptacles. You may have to do some testing to see which wires come from the service panel, and which wires go to the next receptacle, if they weren't marked to start with.....or at least notice carefully which wire goes where on the old receptacle before you disconnect them. 3 Quote Link to comment Share on other sites More sharing options...
