had a call yesterday customer telling me the cooker has gone of and could I look at it .well now the customer tells me that every time he put on the out side lights (XMAS) ones the old string lights the type you find on the Blackpool front ,that the their is a fault .
so me was thinking ok ,plugged in the lights and see what we get .
waited and the mcb tripped .now why would the cooker circuit go off.
me was thinking .
push the test button ,nowt .started turning the mcb off again to show which .breaker is feeding the cooker circuit ,because all on the c/u showed sockets only . and all of a sudden the rcd tripped .
I opened the box front and see what I see . now this c/u was fitted about 14 years ago .

now looking at it again saw the fault laid on the lighting circuit on the non rcd side the neutral came on to the rcd side and the c88P left by the idiot person .
