Sounds like you're confusing 110 with 220
To run your Griz Table Saw (I have the 1023Z) you need to add a 220 breaker (looks like 2 breakers in 1 and takes up 2 slots) to you panel and then have a 4 wire cable (Neutral, ground, 110 Phase A, 110 Phase B) run to the saw.
The gauge of the wire is determined by the distance the saw is from the panel and the amount of current it will draw (in your case 20 Amps). There's a formula for this but I don't have it handy so you should really have someone who knows what they're doing (electrician?) help you if you have any doubt about doing it yourself!
