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.

Be careful with that electrical.

Good overview… I’m one who has done a fair amount of house wiring… lights and 110V outlets; I know just enough to be dangerous when it comes to this level of wiring. I’d call in the pros.

That, and the size of the impeller they use are my two main gripes about the HF 2 HP DC. No ability to rewire to 220V.

Good idea to emphasize that a1Jim, and thats why I inserted the safety paragraph. It is not for tyros. I have been running circuits for 40 years, ham radio operater, etc. Not for the uninitiated. A dangerous and unpleasant experience is inevitable unless you are knowledgeable and meticulous. Kinda like some of my misadventures in woodworking, fortunately I have survived and learned:

ripping on a radial arm saw…......indescribable calamities…......
ripping on a table saw without a splitter….......100 mph flying objects, fortunately I have a little fluff on my tummy…......


I will be writing about the conversion of my saws to 220 as well, if nothing else to remind people of all the things you have to be aware of, just like running our big woodworking tools.

That is one thing about Delta, the motors seem to be good items. Even this new purchase. Gad zooks, there are more things to consider in a woodworker’s purchase, worse than changing barbers or buying a new car…........ don’t want to mention a new spouse…......shhhhhhhhhhhh

Thanks for the post Jim. I have read some real horror stories about do-it-yourself electrical installations here in Norway. One guy’s wife got electrocuted because he got his house wiring wrong. It is actually illegal to do electrical wiring here without a certified electrician’s approval of the work before it is commissioned. Certainly a good idea for folks like me! It’s real easy to do things that can pose real dangers to us and our families without thinking of the possible consequences that a failure could have.

Good point Mike. Wood workers are do-it-yourself people by nature. But the problem with electrical, it has short term and long term consequences that are potentially lethal. My brother’s house (built as a cabin in northern Minnesota, most certainly amateur) burnt down due to an electrical malfunction in a wall circuit that he was running an electrial space heater from. He was not at home, but he lost his dwelling and much of the family historical photos, a bookshelf my father made in high school, etc.

I guess it is an old story. Know your limits. I have been working with electrical circuits for over 40 years. I may be an amateur, but I am a knowledgeable one, with a large amount of practical experience, theoretical background, and no calamities. Mostly I am humble, and always review the latest code and wire strictly by the code. No short cuts. The codes are built to keep it safe. If in doubt, I hire an electrician.

Jim, I as well rarely find myself underestimating the length of time that it takes to finish a job…..why is it that time seems to go so slow whenever I am looking to get into my shop but then once I am there it goes so fast?

Have your say...
