We were lucky; the concrete floor slopes slightly towards the aircon
and the water level didn't reach any electrical circuits. If it had
been an inch or so higher, it could have shorted all the circuits.
Let's see, that's 3 phases times 8 (IIRC) dual sockets, each on a 30A
240V circuit. The UPS wouldn't have helped much, its 3-phase 6 x 30A
circuits terminate in sockets bolted to the same concrete floor. Of
course, the UPS won't actually supply 3 x 180A, more like 3 x 48A;
similarly the raw mains isn't 3 x 240A, more like 3 x 100A.
