I am considering purchasing a stationary air compressor to install in my home’s garage. It will require a 220-240v circuit. Currently, there is no existing circuit in my garage that can power the air compressor. In addition, there is only one remaining breaker space in my load center. The garage is located on the first floor at the front of my home, while the load center is located on the exterior of the house, on the side wall, toward the rear of my home. There is perhaps a distance of 40 feet (rough approximation) between the load center and the location where I want to install the air compressor in the garage.
Considering all these, what would be the best plan of action for wiring the stationary air compressor inside the garage? This is a two-story home with attic space where it is difficult to manuever toward the sides of the home. In other words, as I move away from the center of the attic, I would have to worry about getting my head pierced by roofing nails (if I were not wise enough to wear a hard hat, of course)! There is no basement.
The make and model of the load center is Siemens W2424L1125CU. It has 24 spaces and a 125-amp main breaker.
