New Branch circuit:
Currently there are 3 bedrooms on the same circuit one receptacle a piece. When using the AC it trips the circuit to the entire upstairs.
What's best option for running new branch circuit?
Few thought of options:
1. Disconnect one bedroom from the circuit and run new branch with new receptacle to that room, while capping of old feed with wirenuts.
2. Run entirely new branch to 1 or more bedroom/s resulting in having 2 recepticles in one or more rooms, fishing through wall.
3. your suggestion?

Where do you live, in the USA bedrooms need to be on a Arc fault. I'd also run a new dedicated circuit for the AC, its pulling 240 , right?
