Airbus were rather surprised to learn that resetting tripped CBs was quite routine in the VC10 - whereas in their aircraft it most certainly was not!
The A330/340 doesn't have CBs accessible in the cockpit - they are all under the floor in the radio electrics bay. There are some reset buttons which look a bit like CBs on the overhead panels, mainly for computers, but CB resets in flight aren't allowed or even possible without going 'downstairs'. If a CB pops, the monitoring system lets you know and you can see which one by looking at the CB systems page on the alerting system.
