It started with a blown fuse

We just had another busy weekend in Sydney. Yesterday the weather was very bad so we stayed inside a lot. Today was supposed to be worse but it turned out to be a really nice day. No rain and no storm as they had predicted. We spend the afternoon in the Royal Botanical Gardens where the kids spend over an hour to build a 'pretend' castle.

Yesterday, we enjoyed ourselves trying to use as many machines (washing machine, dishwasher, dryer, microwave, bread machine and coffee machine) as possible at the same time. Unfortunately, the electricity system in our house can not really cope with this. The result was a blown fuse. What followed can be seen on the picture. Instead of telling what happened because that's just too easy, I ask everyone to come up with ideas. So, what happened here? That's the question of the day.
