well this is not a DIY but question for the pros..
I have a 100amp bryant panel in the garage and it powers everything in my house and the garage.
I need a few more 220V breakers for my garage for my tools like compressor and heavy stationary tools, etc. I run out of breakers so I am looking should I pay to have someone install a 200amp service or just add another subpanel for my garage stuff. How much approx would this kind of upgrade cost.
