Hello all...
Ive got an issue here. Im upgading a residential service from 100A to 200A. in looking at the service a privious electrian has moved the older panel from inside (closet) to the exterior. he installed the 100A panel with most of the circiuts extended with 12/3NM. most of the house is now on multiwire circuits.The new panel will requier AFCI breakers for the bedrooms. these cannot be installed on shared neutral circiuts. The old location for the first panel is "around the corner" from the new panels. so pulling new extentions for these lines will involve a LOT of drywall/paint work.. should i run from this project?

thanx
