Anon as this is probably still there
Previous life as Theatre Electrician - theatre in Scotland with a concrete encased basement electrics room containing three phase incomers and main lighting dimmer racks. Local Fire officer required the water sprinkler system remain functional even when it was pointed out water and serious amounts of electricity didn't mix. Even a hint of fire alarms and lx team was not seen for dust.
Same theatre that due to the foibles of hydro power any matinee show in winter meant that at 5pm when the kettles and ovens went on for tea voltage could drop to around 190 and the lighting control boards would just give up - you could be left with every light in the rig live or complete blackout.
