London Consumer Unit Fires.

Zoomup
It is comforting to know that there are apparently no consumer unit fire these days in London (or elsewhere) since all of the plastic consumer units have been replaced by metal enclosure types.


But, do not forget that there might be lots of sub-standard cable cooking and smouldering in people's homes installed years ago.


Lest we forget.........

    I must have missed this BBC news story when it was published. What struck me is the comment "The cable was sheathed in grey plastic and marked with the manufacturer's name. Basec advised that anybody worried about the cable in their home should commission an electrician to test the system."

    If you are asked to test a suspect system, what tests are you going to carry out? As the deficiency is stated to be that the cable has too little copper, the proper test is to measure the conductivity, but for a meaningful result you need to know the length, and if it is already installed in a house that is going to be problematical. The only thing that I can see will work is to look at the cable sheath markings, which the homeowner can do anyway.
