Topic tags/keywords: dust collection dust collector delta 50-760 220v rewire 110v

I picked up a Delta 50-760 dust collector a few days ago off Craigslist. The guy wired it for 220v. I don’t have 220 in the basement shop right now, and don’t want to think about doing that right now. The 110v should work fine as I plan on plugging this into a different outlet than whatever tool it might be hooked up to.

My question is, what do I all need to do in order to rewire this back to normal household current? I know I need a different plug, but am unclear on whether I need to rewire anything else in relation to the motor, such as the switch? I do not have an instruction manual for it. I did a couple of quick Google searches and didn’t find one to download. I’d rather not waste my time digging around the internet as I’ve got plenty of other things to do right now.

I’m anxious to get this up and running ASAP. I’m tired of everyting covered in dust! The shop vac just isn’t cutting it. I bought a Dust Deputy a couple of weeks ago, but it’s still NIB, so I’m going to return it.

Thanks, in advance, for the help on this one.

My first thought is to look at the label on the motor and be double sure that it is a motor that can be wired for 110v current. If it can, look on the cover where the wiring connections go into the motor. Sometimes, there will be a wiring schematic on these covers. You might also contact a Delta authorize service center for information. Finally, Delta/Porter Cable has a great website where you can find users manual, parts diagrams and other information on all of their products. Here is the link:

Hope this helps.

I agree with what Doc said. Your best bet is to get a diagram of the motor.

Doc,

Thanks for that link. I originally checked their site yesterday, but must not have been paying attention, as I typed in the model number and all that came up yesterday was a parts diagram.

I looked a little more thoroughly just now where I had looked yesterday (on the same site you provided the link to), and if I’d have scrolled down a bit farther, I would’ve found the section for manuals, rather than parts section.

Thanks!

I’ll update this once I get it all figured out, or if I have any other questions.

Before I bought this from him, I did check to make sure it could be wired both ways, and it can, so I am OK there. I just need to figure out exactly how to do it. I’m reading through the manual now that I just successfully downloaded from the Delta/Porter Cable site listed above.

OK, looks like I have to do the following:

-rewire the motor
-(probably) get a different switch that puts it back to 120v, as he would’ve had to upgrade the switch that was in there to a 240v switch, so now I have to change it back (argh, I’m guessing this will be the most expensive part here?)
-switch out the plug to the normal-looking/standard prong layout for 110/120/whatever it is

I think that should do it.

Actually, the switch does not need to be changed at all, all the switches that machinery uses is rated at 250V ac. It is the current the switch can safely handle that would warrant change it if the one installed by the manufacturer could not handle it.

However as stated, all reputable manufaturers that make equipment that can be used in either voltage would use a switch that can handle both conditions (The higher current when running at 110Vac or the higher voltage when run at 220 Vac).
By the way I own one miself, love it!

So in order to do what you want to do, you just need to rewire the connections in the terminal box of the motor and change the plug.

Have fun….

jerryz,

That makes sense. Don’t know why I didn’t realize that? Guess I was just getting confused when trying to read a few basic conversion snippets. I think the problem was, those were talking about converting the other way, stepping up to 220v, rather than down from 220v to 110v. That’s where the mention of the switch was at.

Thanks for the clarification.

I converted all mine to 220. I know the methods. there should be a small box attached to the motor. if you open it you will see wires and wire nuts. there are two configurations one for 120 and one for 220. genrelay there is a sticker with a diagram for each. the manual also has this diagram and instructions.

You can get a plug with wires loose on one end (appliance plug) at the home depot. the switch should open up and the plug can be wired in place of the old one. if the switch is not 120 rated which is unliekly you can get a new one fron grizzly on line.

the principal differnce between 120 and 220 wireing is that there is no netural(white) in 220 its two live (black or black and another color) this is evedent when you look at the motor or in the switch wire up.

Here’s what my switch looks like on the inside:

The outside of the switch is identical to the picture on the Delta parts list on their site, listed as part #35:
http://servicenet.deltaportercable.com/Parts/Detail/261476

I did not do anything to the switch, I just undid the 230v plug, then following the diagram on the inside of the cover, rewired the 115v (new) plug, according to the directions.

When I plugged it in, it turned on and I haven’t had any issues since I rewired the plug. I now have it plugged into a remote switch that I keep near the TS on/off switch.

Jonathon,

You mentioned that you are using a remote switch with your Delta 50-760. What kind is it? I found that I can’t use an iVac switch because the breaker trips, even though it’s rated for 15 amps. I would like to find a remote that I know will work.

Thanks,
Jerry

Either of these should work for you:

(I have this one… I got it on sale for $50-something?):
http://www.rockler.com/product.cfm?page=10740&filter=dust%20collector%20remote
It works well.

I also considered this one:
http://www.woodcraft.com/Product/2005117/8394/110V-Remote.aspx

They are more or less the same thing.
