I would like run two 20-Amp circuits to a 2-gang box with two duplex outlets.
One duplex outlet on Phase A and the other on Phase B.
I know to keep the hots and neutral separate and that the grounds can be combined.
Is there anything special I need to do at the panel?
For example, should I use a tandem breaker with these two circuits.
More clarification to come.
All work will be inspected by the city that I live in. I want to make the inspector proud of me and my quality work. I am taking no short cuts. If the inspector makes me do it again, I'll do it again. This is how I will learn.
The work will on a 2-story unfinished 20x24 detached garage. The second floor will be a studio apartment style (for my personal use only - no renters). I plan to use the first floor for combo car-garage and workshop (car/wood/kids projects/etc.). I do not believe I will need any 240V circuit.
The idea is if I have a 120V air-compressor and 120V ShopVac running at the same time, I did not want to start tripping breakers. All the equipment would not be stationary. For example, I can move everything to one side if I need to work on a my car.
Trying to plan for a future requirement is driving me crazy. So I am trying to build in flexibility so I want have to bang my head on the floor too hard.
I had the panel upgraded to 200A Eaton Plug-on Neutral and I have currently installed plug-on neutral breaker (GFCI/AFCI combo).
