My mains electric circuit is bust! The 30A fuse in the fusebox went on Friday. I removed all the plugs from the sockets (except the washing machine and frdige) and rewired the fuse, turned the fusebox back on and it lasted about 10mins then blew again. Then I unpluged the washing machine and fridge, rewired the fuse, turned the fusebox back on, and it blew instantly! I have an electrician coming round first thing tomorrow but is there anything I can check before he comes to save me money?! A friend told me to unscrew all the sockets and make sure no wires have come loose, then check for any water leaks... Could it be the fusebox? Thanks loads in advance... I'd be grateful for any advice
