No fault on this circuit, just the fuseboard is worn out and has come to the end of it’s usable life – in the block of flats where this was found all of the fuseboards were installed when the block was built – it therefore follows that all 68 of them need changing – I think we are going to busy following this call.. if you are worried about you fusebaord, don’t take a chance give us a call and we will check it is OK.
