Hello All,
I live in an old Edwardian house, which has an extension built about 7 years ago. I have a range cooker which has its own electrical RCD fuse. There are several more fuses for the old downstairs sockets and the new extension sockets. I had to move a microwave into our kitchen this week. On top of my kitchen cabinets there are two single sockets. One is used for the fridge and the other has a 4-1 adaptor with an extractor fan in it.
On moving the microwave I had to use an extension lead (1.5mm cable 13 amp plugs) that then plugged into the 4-1. So far so good. After a day or so the cooker tripped out when I turned it off. It blew fuse 1 which is the cooker. The microwave stayed on and everything else. Bugger I thought. So I tried without the 4-1 pluging it directly into the socket. Now its worth mentioning that the two single sockets seem to have other grey wires feeding into them which I suspect isnt ideal. Anyway after turning the oven on and off rapidly a few times times the fuses blew again - fuse 1. I have also tried plugging it into the fridge socket which should be on a separate fuse - each time the issue is with the cooker.
If I plug the microwave into another socket in the house I get no such issues. The cooker is fine. Can someone help me explain this ? If the sockets were on the same circuit as the cooker then I would expect I was overloading the circuit - but why is the microwave/fridge staying on?
I dont understand electrics so I am sure this is a simple answer......Also is there anything I can do here to use these sockets rather than a have to route a cable somewhere else?
thanks
Brian
