I am building a detached garage in DC, fully permitted. For electric, I want PEPCO to install a new main breaker box in the garage served directly by PEPCO's overhead line, rather than a sub-panel served by the existing main breaker in my house. My house electric is old and I suspect that getting a new sub-panel would involve redoing my entire existing main breaker and would cost many thousands of dollars. My thought is that I could leave the current house electric as-is if PEPCO will install a new main panel just for my garage. If PEPCO will do this, I bet they charge a lot. Can anyone weigh-in on whether or not this is possible, and if so, is a new main breaker through PEPCO going to be cheaper?? Any thoughts appreciated, but the electric must be permitted (neighbors, etc.). Thank you.
