Narrative:

Aircraft ECAM caution that left outboard fuel temperature was 58 degrees C; limit for takeoff is 54 degrees C. First officer called maintenance control; controller said to 'turn-off the IDG1.' first officer tells me; I stop the aircraft (parking brake set); I asked the first officer to verify with maintenance control the requested action while I listened to the radio communication. Both of us heard the maintenance controller say to 'turn-off the IDG1.' after the confirmation; we turned off IDG1. After arriving at the gate; I made an entry in the logbook that maintenance control had us turn off the IDG1. When I called maintenance control to get the controller's number; he refused to give it to me. He then told me that we had 'misinterped his instructions' and 'that he could prove it with the recording.' I contacted the chief pilot's office and explained the situation. Callback conversation with reporter revealed the following information: reporter stated when the maintenance controller directed them to turn off the 'idg' the second time; that's just what they did. This switch actually disconnects the 'idg.' he does not know what the fix was for the original high fuel temperature problem. Reporter also feels the controller may have limited experience or familiarity with the airbus electrical system.

Narrative: ACFT ECAM CAUTION THAT L OUTBOARD FUEL TEMP WAS 58 DEGS C; LIMIT FOR TKOF IS 54 DEGS C. FO CALLED MAINT CTL; CTLR SAID TO 'TURN-OFF THE IDG1.' FO TELLS ME; I STOP THE ACFT (PARKING BRAKE SET); I ASKED THE FO TO VERIFY WITH MAINT CTL THE REQUESTED ACTION WHILE I LISTENED TO THE RADIO COM. BOTH OF US HEARD THE MAINT CTLR SAY TO 'TURN-OFF THE IDG1.' AFTER THE CONFIRMATION; WE TURNED OFF IDG1.
