My wife woke me up early this morning. She had got up to go to the toilet and noticed a problem with the fish tank and couldn't suss out what it was. Anyway to cut a long story short there appeared to be, for want of a better explanation, less electricity coming into the house. Nothing had tripped, but a lot of the lights and things weren't working and those that were seemed to be at a reduced power. So, for example, the lights that would work were operating like a torch which needs new batteries. After about half an hour of scratching my head and looking at the fuseboard as if I knew what I was doing everything kicked back up to full power. Anybody know what could have caused something like that?
