I was working on two 20A 110V circuits in my shop for some time. It is not
that bad but I always felt limitations in choosing my tools. Finally, I need new
cyclone dust collector and needs on better electrical lines. Even those (CD)
which will be enough for me require 30A because they suck too much power on
start up. I am deciding on getting two 220V circuits. Will 20A be
enough? I know it is enough for DC, but what if I decide to buy, let say
Hummer 4HP table saw, will it work on 20A? I do not want overspend (who
does?) for overkill, but definitely would be good to have some room ...
What your thought? My shop is small one car garage and I do not run many
machines simultaneously. Basically, one machine + DC.
