Narrative:

We taxied out and we're on the ramp with ground when all flight instrument and ECAM screens along with control panel lighting went out for approximately 4-5 seconds. Power was restored and; after evaluating the situation; we accomplished the QRH procedure for a #1 generator failure. It would not reset so we returned to the gate after notifying ops/maintenance. Maintenance deferred the #1 generator; but I let them know that I felt the aircraft did not properly switch power sources. Cockpit should not have lost 'all' power (screens; instruments and lighting) for that long. With summer thunderstorms along the whole route I did not feel that taking this aircraft was a smart/safe thing to do. I refused the aircraft. Dispatch had another aircraft available.
