Although it is already confirmed that the captain did not get out of his seat to pull the CB (this can not be 100% trusted IMO), I want to point out on thing. CBs are not "normal" controls and there is not CB schematic availible to the pilots (I guess maintenance has it, because they use CBs more often - but to pilots its not a normal control). I'm wondering why the captain should have known the location of the FAC cb and was therefore able to find is quickly? Yesterday I looked for it during a long ground stop just out of curiosity and it took me around 2 minutes to locate it. I can image that an experienced captain knows the location of the CBs that are used from time to time (approved reset procedures, that occur rather often...) - for example I know the location of the FMGC 1 + 2 CB by heart (I'm still a rather new FO on the A320), because I needed to use them several times already (but of course I didn't do the reset by heart, but with reference to the approved procedure in the manual!). However as several people already pointed out there is no approved FAC reset procedure involving the use of the CB, the only approved reset (for flight crew) is done with the FAC pushbutton.
