I am building a detached garage 300' feet from my home and main breaker panels. The meter is out by the road right of way 450' from the home. The garage is going to sit somewhere in the middle about 150' down the hill. Rather than tap into the house panel I'd like to come right off the meter at the top of the hill. The local power company will not allow a DIYer to touch there meter or feed so I know I'll need a licensed, bonded electrician. My question is, is this a sound plan and will most power companies allow a second tap off a meter. Also, at present I only need three 15 amp circuits in the garage panel but for future expansion want 240v. How large of a wire should we use coming from the meter to the garage? Any other suggestions? The soil is mostly rock and I will have a heck of a time driving a 10' ground rod.
