branch circuit to removed A/C unit

I have a question about branch circuits that are not connected to a load. I am working on a house which had central A/C, but the condenser unit was removed for scrap by some scoundrels. The circuit breaker, wiring and outside disconnect box which served the condenser are still in-place, and the owner plans to install a new condenser unit next spring.

I'm wondering what the owner's options are under US NEC: if the outside disconnet box is locked and the wires inside are capped and taped, can the disconnect, branch circuit wiring and breaker remain? Or does the breaker need a lockout/tagout? Or must the breaker and wiring be removed altogether, if there is going to be nothing connected to the circuit for 8 months?

The circuit can remain, but must be safe. As long as the circuit is properly terminated in the disconnect and the breaker is off, it should be fine. If you want to be extra safe, disconnect the wires at the breaker too.
