    If a CU caught fire, and it was shown that at least one component was not approved by the original manufacturer, and that led to the fire; and the electrician who put the component there is known; and there were greater than trivial losses, litigation might take place. Even then, it is likely to be settled out of court.

    Failing to comply with BS 7671 (or any other standard) does not usually break the law, but it would hardly help a defence in negligence.

    So I think that there are two questions. (1) Do the standards permit mix and match? No. (2) Would you take the risk? That is, of course, a matter of personal choice.

    Type testing is set out in the standards and is both complex and expensive.

    I can understand whjohnson's cynicism. It is all about personal attitude to risk.

    Along similar lines, would you fit manufacturer's brake pads or a different brand from your local motor factor? Do you (deliberately) break the speed limit?
