Not that I know but I assumed that an AFCI _could_ detect an arc on a broken or lose wire where the arc was phase - phase? I take it that it will trip on a phase - neutral or phase - earth arc where a normal breaker wouldnt because the current being used in the arc ist sufficient to cause an overload or short circuit condition.

I wonder if they will make an appearance in the UK. Overheated or sparking connections dont seem as common from what I have read and seen, except on shower circuits >7kw mainly down to dodgy DIY!
