Panel of doom

Went for a run after work today while J drove down to Portie to Run Kilda and I headed down to meet them. While we were having dinner we noticed the electric had gone off again. Happened a couple of time in the last 6 weeks. This time I confirmed it was the downstairs sockets which we have the BT hub all the network points, downstairs door buzzer and TV system. Right pain in the arse. Went through un plugging each item and testing the breaker again with no luck, its not something plugged into the ring main that I can find which is a bigger problem. Had to run  and extension lead from the other side of the kitchen, under the rug to run the BT hub to get the internet working fro J to work from home tomorrow.
