Background story about the power blackout at Megabit last night

From What The Wiki?!


Last night at the Megabit tent we had several power blackouts. The reason was water from the bar (not the rain as far we can see). Behind the bar there is a small drain tank for the sinks and a pomp with a floater to pomp the water away when the tank is almost full. But someone put a 230V division box near the tank to power the motor and the cooling for the beer taps. I think someone spoiled some liquid over that division box and the earth leakage protection in the distribution box nearby the generator turned our feed off.

Becase the earth leakage protector at the generator has a sensitivity of 300 mA and our distribution box 500 mA we needed to run a few times ;) .

To prevent this for the next time we placed a third distribution box with earth leakage protectors of 30 mA. So "if" something goes wrong at the bar, only the bar goes off and not the lights and music.

update 18:38 The second distribution box did not operate in the right way when i connected an arcade game 'Space Invaders'. So, we decided to get an another feed from the distribution box by the generator. If something goes wrong, only the lights or the music goes off. And we can just react very quickly to fix it (like max 10 seconds.)
