Double insulated appliances.

Kevin Brodie

Good afternoon, can anyone tell me when double insulated appliances were introduced to the market.

    I was not aware of that one - I was aware of  it pre-dating the IEC classes but not by more than a decade. (makes the B and D campaign  quite late actually - I have since found this amusing read.  Double Insulation The Black & Decker Story (PDF) )


    Odd perhaps that we did not retain 2 pin sockets, had double insulation been a little earlier, or 13A plugs a bit later,  we may well have, as the idea of a compulsory CPC to each socket circuit only really appears in the post war regs. (to be followed less than 30 years later by CPCs in lighting circuits as well.)

    Mike.
