I have a garage unit of Wylex make with 6A and 16A MCB's. This unit is on the recall list. The installation date is around about the problem period possibly later. Given that stuff can be on the shelves for months how can there be any certainty that the dates quoted will catch all potentially faulty units. There are codes on the back of the MCB where the DIN rail goes, If I am correct in presuming that these are batch codes why have these not been quoted in the recall notice? How can I identify if my unit is affected?
