I just got a delta 36-725, and I just blew a fuse cutting through 4×4 fir for my “I’m too cheap to buy hardwood” dining table. Right now, I’ve got two 15a, 110v circuits in the garage. Both are shared with the rest of the house. For what it’s worth, I’m very comfortable with electrical work (electrical engineer and worked my way through college, among other things, as an electrician/plumber’s helper.) I’m mostly asking for opinions on what would be more useful long term as I’m planning to get back into woodworking in a pretty big way. The panel is in the garage and has plenty of capacity (about 10 slots available, 200amp service with only 140amp wired up without overloading right now), so whatever would be best is pretty easy to implement.
As I see it, there are two plans:
Plan 1: 2 20amp 110v circuits, one dedicated to table saw
Pro’s: everything stays 110v, no need for special extension cords, can plug anything anywhere. Have two dedicated circuits for other benchtop and portable tools as needed.
Cons: If I ever get that welder, no place to plug it in.
Plan 2: 1 10amp 220v circuit for table saw, maybe go ahead and run 1 or more 110v circuits too
Pro’s: ??? from what I understand, there’s not a huge advantage for the table saw to convert it to 220. I’d have a plug for that welder. Also, a plug to attach a generator to the house if I ever need to in a power outage.
Cons: More wiring, have to rewire table saw with a long enough cord to actually reach the center of my shop (not practical to drop power in the center), etc.
Plan 2.5: Do the 220v circuit while I have the box open, but leave the table saw running on 110v.
Con: Cost, more wiring, redundant unless I get that welder.
Plan 3: do a subpanel, all surface mount conduit, so that I can implement plans 1 or 2 without having to open up the walls.
Pro: Future expansion is easy. Eventually, I want to air condition the place so that would make it easy to wire for that.
Anybody with more experience care to comment? The only gotcha is my space is already drywalled, so I’d rather only do this once. It’s a fairly small garage (14×24) so I don’t know how much more equipment I can pack in anyway.
Thanks for your thoughts.
