I plan to replace that c/b with the same make and model 30A breaker, disconnect and cap the wiring to the "computer room", then run new wiring to a TT-30R receptacle outside. It will be in a weather-proof box with a weather-resistant "in-use" cover. I'll be getting a neighbor who's a professional electrician to look over my installation before I activate it.
I am assuming the reason you are disconnecting (and replacing) the circuit breaker to the computer room, is because the breaker box is completely full...and you don't have room to add another circuit breaker. (or you are using up all your service amps)
If you still had room/available service to add another breaker, you could just add the 30 amp and run the correct size wire from it to your TT-30R.....without disconnecting your computer room.
Have you looked over the pdf file on making sure you wire the TT-30R correct?
