AFDDs and bated breath

The IET/CEF webinar on BS7671A2 a few days ago was a good entertaining, production which was easily digested. At one stage Darren turns to Mark and suggests that we are waiting with bated breath as to whether Mark in consultation with colleagues from ESF will prescribe a code two or three to the absence of AFDDs in an installation. Their decision will then be published in a new Best Practice Guide for periodic inspection and testing. 
I trust that the Guide will keep to domestic installations. Straying into areas where BS7671 mandates AFDDs will cause serious issues with the statutory requirements attendant with those installations. The absence of such devices in these circumstances is best left to professional fire risk assessment rather than some arbitrary declaration that does not have knowledge of the individual premises or the control measures that are in place.

  • Who advises local Councils on the implementation of changes such as this, are they instructed by the Department for Levelling Up, Housing and Communities or whatever they are called this week?

    I know Charlotte Lee at NAPIT used to be involved with lobbying on such matters at Government level through the Electrical Round Table as well as being the members forum moderator keeping ex members of this forum in check. Joy

    However the Electrical Round Table seems to have gone quiet since before Covid, I don’t know what they are up to these days

  • I wonder how they are going to reconcile the increased loading on the grid if these things are mandated across the board.

    Imagine a installation such as offices, a hotel or HMO with multiple dist boards, never mind the 28 million homes, each with at least a 10 way CU.

    How much power does a AFDD consume?

    They can make it a whichever 'C' code they like, but it won't mean that a previous installation assessed and considered 'safe' will have further moneis spent on AFDD upgrades. Indeed, we can look forward to much belt tightening in the forthcoming couple of years. The lack of a AFDD won't get people to open their wallets, not at a hundred quid a chuck for some dubious unproven benefit.
