AFDDs NEW REGULATION IN AMD 2

John Peckham

As you may be aware amendment 2 to the 18th Edition was published in the early hours of this morning. If you have the access to the IET Digital package you may have already seen this change.

The new regulation is.

Arc fault detection devices (AFDD) conforming to BS EN 6206 shall be provided for single phase AC circuits supplying socket outlets with a rated current not exceeding 32A in.

High Rise Residential Buildings (HRRB)

Houses in Multiple Occupation (HMOs.

Purpose built student accommodation.

Care homes.

For all other premises, the use of AFDDs is recommended for circuits supplying sockets not exceeding 32A.

So we will not be seeing consumer units full of AFDDs if at all in ordinary domestic premises.

Lights blue touch paper and retires.

  • If the enemy is supposed to be arcs forming in flexible cables and plugs and sockets, then it is surprising that temporary installations (building sites pop festivals, film sets and so on) have not been put in the focus as the folk who use flex by the kilometre and far more plugs and sockets than anyone else.

    I imagine it is more the fact that no AFDDs are made for circuits with as low a current as the MCB as a typical UK lighting circuit .

    Of course we do not have the culture of unfused extension leads that are the norm on the continent and the US.
