I have a Northtech DC Model NT-DC-20-1. It is currently wired for 110. The data plate shows the capability of 220. The wiring print inside the cover does not define the terminal swap clearly. I was not able to locate a manual on line so I thought I would post the wiring print in this forum to see if someone is more electrical savy than me to figure out the terminal move. Thanks for any help with this!

That is a less than useful diagram. Do they have an 800 number? You may also find a similar diagram for a different tool that is close enough with better instructions. If all else fails find an electrician friend and a 6 pack. Good luck.

That diagram is only for the motor starter. The motor wiring diagram should be either on the motor nameplate or inside the peckerhead cover.

Update. After further review, I found another cover over the motor itself and on the back of that cover is a small diagram code that shows how to switch the terminal from 110 to 220. I have not completed it yet but it should work fine. I am in the process of moving the DC to the room above my shop and plumb the 4” runs through the floor to cut down on noise and to free up more floor space.

I really appreciate the replies. I am making good progress on converting my DC to 220. I got the 220 wiring figured out, which is good. I am now ready to move my DC up to the room above my shop and plumb the runs to the shop below. I now see that there is this push button magnetic switch box which is used as a holding starting circuit. I was going to plug my DC into a remote switch box so I can turn it off and on remotely from the shop below. However with this push button mag switch box, I realize that this type of remote switch box will not work because the mag switch box needs to be hot and then actually push the buttons meaning I would have to run upstairs to the DC to push the on – off buttons. So looking at the attached photo, this push button box is just a detached mag box electrically connected to the motor through a wire feed. Do you guys see any reason why I can’t mount this mag push button box down below in my shop and just run a longer feed wire up to the motor on the DC which will be located in the room above the shop? This way I can turn the DC off and on from the shop below?? Thank you!

So, why are you going to the trouble to wire it for 240V? Actually 220V doesn’t exist anymore, when out fashion about 50 years ago.

I assume that mag switch can handle either 110/220 since it is included on a unit that can be switched, but many of the aftermarket switches are one or the other. Just worth a check. If you’ve already tested . . . never mind
