I need to add more power to my garage as I'm using it to power lots of power tools. The current breaker only holds about 10amps, I need to know how to get more juice flowing to my work space? The main panel is a 200amp box, I will provide more info if needed. A rough estimate of pricing for this job would be appreciated as well. Thank you. Along with power tools, I would also like to add an AC unit in there because the heat could become a health hazard during the summer months. How big of a circuit breaker should I be looking at?
