A320 ELEC EMER CONFIG and gen reset
Going by the ELEC EMER CONFIG checklist, GEN 1+2 has to be set to "off" and then 'ON". If one of the gen is reset successfully, would the successful gen power all the buses? I understand that in the older version of A320, DC and AC ESS BUSES continues to be supplied by EMER GEN until landing gear extension. However, there is no such explanation given regarding the successful outcome of a GEN reset with respect to the latest version of A320.

AC abd DC essential busses remain powered by the emergency generator even if you manage to reset one of the main generators. The is done to protect the AC and DC essential systems. However what powers the emergency generator changes. In the emergency elec config the RAT powers the blue hydraulics, which powers the emergency generator. If you get a generator back on line and it powers everything normally, then the blue hydraulics would be powered by the blue electric pump. But the RAT would remain deployed and engaged, so if the generator tripped off again you wouldn’t have to wait 8 seconds for the system to reconfigure.
