I'm upgrading a house from 60A to 200A. The old service connected via weatherhead to the side of the garage but the main panel is in the basement behind the house. This garage was finished into a living room years ago and there is no way through it.

Can I leave the service mast where it is and use a LB to go around the back of the house? I've tried to find something saying the the mast must be a straight run into the meter box but I haven't come up with nothing. If I can figure out how to post a drawing I will.
