I just bought a new delta 10″ hybrid table saw. It is wired for 120V. My garage is a little distance from the main electrical panel.
My old contractor saw seemed to blow the breaker an awful lot. The new saw is 1 3/4 horse. If I run an independent 12/2 from the garage to main panel and put it on it’s own 20 amp breaker, do you think that would be enough power without having to run a sub box?

You need to know the amperage. There is a formula to convert HP into amperage, but I dont have it in front of me. Amperage should be listed on the nameplate. If it is less than 16A and eighty feet from the panel, than 12/2 would be fine.
I had the same problem years ago when I had a separate shop about 150' from the main. I ran 6 G down off a 50A sub and never had any problems. I wired it so the heavier machinery, (TS, planers & shaper) was dedicated to only that circuit, plus one heavy duty 110v for the bench. Being only one person in the shop at once I never used anything heavy at the same time.
There was one other 12 A circuit that had been there for the lights.
Before that I had only a 12/3 running down there for all my stuff and the drop in power was killing my tools. I had to rewire my cabinet saw after that for 220.
A small shop should have 60 to 100A with the sub panel nearby. It just makes things easier.
Should be fine.
I run that same saw at the end of a 100' run and circumstances dictate only 15A/120V circuits possible. Dust collector is on the same circuit as saw as is jointer and I often have all three running at the same time. Breaker does blow on occasion when I overfeed while ripping dense 2" oak with the other machines going but generally it isn't a big issue. You should be fine with a dedicated 20A circuit, but if you can run new wires you should consider 240V. The saw motor hookup can be rewired for 240V.
