You have to look at the specs of panel to see if allowed.Should say on there somewhere.

That is a twin/tandem/skinny breaker, not a two-pole breaker. That breaker will NOT give you 240v. It will give you two 120v circuits.
You need TWO spaces for a 240v circuit.

IF, and only if, your panel will accept twin breakers you can use one to free up a space in your panel by consolidating two 120v circuits to one space. Even this has risks so be sure you know what you are doing first.

Also, what size circuit do you need? "220" means nothing without more info.

The circuit you need will be 240v at a certain amperage. The amperage is the size of the circuit.

No it can not be done. A double breaker only connects to one leg of the service a 220 break connects to both legs.

Every other slot is on a separate leg a 240 volt break takes up 2 slots so it is connected to both legs rather than one.

You might use the double to replace a two 120 volt breakers thus freeing up another slot and install a double breaker.
