Somewhere on the first two pages somebody said the four generator control units for the four generators were close together and all got hit by the water from the galley
Not so. Generator Control Units 1 & 2 plus Bus Power Control Unit 1, are situated on E1 shelf. Generator Control Units 3 & 4 plus Bus Power Control Unit 2, are on shelf E3 at the opposite end of the rack, quite a long distance apart and I find it difficult to comprehend that all of them were flooded.
