Are we just kicking this around for fun?
I mean is any service sized so close that a garage door opener is going to make a difference?
If the answer is yes, is anyone changing a service when they add an outlet for a new 15 or 20 amp circuit for reasons other than lack of physical space in the panel?
I can not remember ever hearing of a service main tripping from overload.
Ground faults, short circuits sure but not an overload.
All I am saying is, aren't we over thinking this?
