My workshop sub-panel is powered from two dedicated 110V 40A breakers off the main panel 100 feet away. The sub-panel has adjacent open breaker slots available. The four existing 110V 15A breakers supply lighting and outlets.
Can a 220V circuit be added to the sub-panel for a new power tool...
I want to install a sub-panel with 8-20 amp breakers.
What is the minimum gauge wire needed from the main to the sub panel?
what is the minimum size breaker needed in the main to feed the sub?
Thanks.
