I am currently in need of a new 240V circuit for a welder in the garage but my main breaker is full. Adding a subpanel seems to be the only solution that would be to code, but I have a couple questions on the specifics.
First, There is already a subpanel that is powering the basement, but its distance from the garage makes running 10-3 cable a bit difficult. Is it ok to have two subpanels?
Second, assuming I could install another subpanel, how should I reorganize the circuits? Would it be a good idea to move all lighting and misc (15A-20A) circuits to the new subpanel and keep the existing/new 240V circuits in the main breaker panel?
