The Delta 50-760 Sawdust Collector comes wired for 110 volts. Had some issues with lights dimming, especially when running the sawdust collector and one of the big saws. I have decided, therefore, to put the dust collector and the two saws on 220, and then put a line stabilizer on my wifes longarm quilter circuit. The dust collector, in particular, seems to be an amps hog. I had seen a post about the noise level and pitch changing and becoming obnoxious on 220. So I approached it wondering if it would work out. In fact, that is the main reason I decided to post about this.
Since it was on a dedicated circuit, I put in a 220, 20 amp breaker and moved some of the breakers to avoid any splicing. Only need a 3 wire circuit for this level of amperage, so no new wiring, but colored the white wire red as per code. Had to replace the remote switch with a 220 one from Woodcraft. Replaced the socket in the wall, cut off the plug on the dust collector and replaced it with the proper 220 one. Then switched the wires around on the motor…they even had included an extra wire nut in the housing to do this. Turned it on…it sounded exactly the same.
Time expended, including moving the collector, cable tying the wiring at the remote, screwing it into the wood panel the remote is on, changing the DIP switches on my other 3 fobs, collecting tools and putting them away, about 1 1/2 hours. Thought it would take less, of course I think everything will take less time. I have never overestimated the amount of time some project will take. Go figure.
The unchanged noise makes me wonder if the person who noted the noise change was running a significant voltage drop on 110, and 220 brought the motor up to normal performance. There should be no change in power as I understand things, unless you have house wiring problems. The collector is noisy, but not overly so, I don’t feel required to wear protectors because it is on.
Now only a flicker of the lights, but no dimming. Now have to do the saws, but for that I have to run a 220 circuit. I ran the original 110 circuit about 25 years ago, so it doesn’t present a problem for me. But I need the 110 for some lights and small tools.
Should someone who has never done electrical much do this? Not recommended. Best get an electrician. Second best, find a friend who is knowledgeable to help you. I can see some hazard points, I’m guessing you could destroy the motor, or get a shock, or create a fire hazard. From what I read around here, a large percentage of LJ’s feel comfortable doing this kind of thing, but the uninitiated should not just jump in and do it. I reread the code, made sure I had all the proper plugs, receptacles, etc. and have done this sort of thing untold times. It used to be a necessary skill if you lived in Alaska. Plumbing even more so.
The main note: No change in noise level or character on 220 versus 110 for the Delta 50-760 Sawdust Collector.
