Narrative:

We were climbing to cruise altitude when ECAM chimed ECAM ess bus shed; used QRH; ECAM; and supplement book for fault. Reviewed form for restrictions to over water operation; aircraft not allowed over water with malfunction. Call maintenance; told them of problem; explained situation and advised to return. All primary systems were normal. Power plants; hydraulics; and normal electronics. Consulted QRH for overweight landing. Did not declare an emergency. Landed at 142.2 gross weight vertical speed less than 100 FPM. Landed normally and taxied to gate. Maintenance advised aircraft had same problem day prior. Breaker popped in avionics bay. Many items affected by fault.
