So one of the very first things to get done this spring is I want to have more outlets and probably another circuit or two added to the garage (theres currently one 120V, 15amp circuit feeding the whole garage, and only one outlet with easy access to what will be the shop area! Eeep!)
Anyways I’ve been reading up on wiring and such so I know enough that when I get an electrician out here we can determine what I need. Now all the tools I own currently or plan to buy in the foreseeable future (including a better table saw, although the one I’m looking at can use 110 or 220) all run on 110V and max out at 15amp. However from the reading I’ve been doing, I keep seeing recommendations to run a 240v circuit since at that voltage the amp draw is cut in half.
So what I wanna know is, is it safe/possible/wise to run a tool that normally uses 110v on a 240v circuit or will that damage the tool/blow the circuit? For that matter, what if you plug in a 220v tool to a 120v circuit (assuming you have enough available amps to feed the tool in either case)
I want to understand as I want to add as few new circuits as necessary to keep costs down, tho I’ll add however many is necessary. Currently thinking a 20 amp 120v “general” circuit, and a 20amp 240v “tablesaw” circuit. Things like lighting and battery chargers will continue to run off the original 15amp, 120V garage circuit
‘ppreciate any insight/advice gang! (btw everything I have/will get are lighter “hobbyist” level tools, nothing industrial quality…YET!! lol)
