Arc Fault Detection Devices

Hi Everyone,

I'm just wondering how everyone is faring with AFDDs, especially in commercial/industrial installations?

421.1.1 states that you shall protect against "insulation faults or arcs, sparks and high temperature particles", yet 421.1.7 only recommends AFDDs,


What are everyone's thoughts?


Thanks,

    Both are valid points,

    Ensuring that terminals are tightened correctly, mechanical protection is sensibly installed etc. goes some way to stopping the arcs in the first place.


    Do you think that they will become mandatory in future amendments?
