The Arc Fault Detection Device… again.

whjohnson
Some humourous but valid observations on AFDDs, the state of the industry, the wiring regs and future amendment requirements.

He also attempts to build a AFFD tester which electrically tests rather than relying upon the mechanical action of the test button on the device itself.

    Hello Farmboy.

    Good one!  I was rather engrossed in my own situation of low current, personally monitored and/or off!  A series fault in a BS 6004 cable running above 2 amps could be a candidate for an AFDD.  I wouldn't fit one left to my own devices because, after a lifetime in the industry I haven't met such an incident that resulted in a fire.  However, it looks like we'll soon all be made to.  Mainly good for the manufacturers' and their shareholders I think.

    Regards,

             Colin.

     




    Hi Colin,


    I was interested in your perspective because other more learned members than I on the forum seem to have been focussing on the technicalities and motivation(s) regarding AFDD installation, whereas yours seemed more from an interested users viewpoint (the other side of the coin, so to speak). 


    Personally, I think they're just one big con, and to alter a borrowed phrase: they're designed by computer, built by robot, installed by reluctant doubtors and used by the clueless - all pushed by alleged financial greed in the apparent face of no credible evidence of efficacy at all. We'd be forgiven for thinking this is politics.


    Regards
