AC Disconnect for Mini Split Air-conditioning

Hello, I'm planning on installing a mini split condenser unit that requires 240v/30A. I need to run a dedicated line from my breaker to an AC disconnect. I need to know if my plan is correct. I'm planning on using 10/2 Romex and run it to a 30A double pole breaker. Any insight would be greatly appreciated! Thanks!

Welcome to the forums.

Running 10/2 NM-b from a 30A double pole breaker to a disconnect.

The protection is the breaker in the panel. You can use a non-fused disconnect.
All you need is a 30A disconnect but typically the 60A version is easier to find.

A/C disconnect

Remember you will also need a 20A (GFCI Protected) receptacle in the line of sight of the condenser (outdoor) unit. When the apartment I live in installed mini-splits they used These combo disconnects with an integrated receptacle. I think you do need an additional 12-2 for the receptacle though
