Adding a new Ductless (Mini-Split) AC

Hello all,

Having a new ductless AC unit installed today. Moving one of my existing ECS1050 CTs to cover this new circuit. Wanted to verify how the CT should be attached. Was planning on attaching the CT to one leg … assuming I would need to then check the double box??

Thanks for your help!

That should work fine assuming your unit is 240V two wire, which is most common and suggested by the black/white wires connected to the two pole breaker in the picture.
