I just purchased the grizzly G0513 17” bandsaw, it comes prewired for 220, i dont have 220 in my shop, i can add it if i had too, it can be converted to 110, it has a 2 hp motor, what is the advantage of 220 compared to 110, and what wire do i need for a 110 hook up, there website says 110/20 amps 220/10 amps, i have a 30 amp breaker for my tools in my shop, i dont run more than one tool at a time usually, maybe one saw and the jet dustcollector. Any thoughts would be greatly appreciated:)

The saw draws a certain amount of amperage, from the Grizzly spec sheet:
Minimum Circuit Size…..........................................................20 amps at 110V, 10 amps at 220V

So running it at 220V means less current draw. Your wiring does not need to be as robust as running at 110V which will draw 20 Amps. You are going to pay the same amount on your electric bill since that is measured in kilo-watt hours. Watts are Voltage Amps, so 20110 = 10*220.

However, to run at 220 you would need a 10-Amp 220 breaker and run 220 wire (dual conductor, common and GND wire).

There should be no reason you cannot rewire it to 110V and run it off the 30-Amp breaker you have since you only run one tool at a time.

Hope this helps.

There is no cost savings running at 220 over 110. You are still drawing the same total number of watts. The advantage I have found running 220 is that (and this could just be my imagination) the motor wills spin up faster will have more torque which will help when making heavy cuts. When wiring 220v shop tools, most only require 2 hots and a ground, you don’t need the common.
