Hi, i just moved into a new house and it has a garage with no electric in it. I need to run 220 to my garage. My house main panel is all full. Do I need a another panel in my house or can i i just put a new main in my garage by jumping the one form my house and also what gauge should i use to to run from my house to the garage? I will be running the wire through the ground. Thank you for all your help.
