AFDDs AMD 2

John Peckham
In response to the suggestion of separate threads for individual changes to the 18th I thought I would start this one for AFDDs.


So what are the forum members views on the new requirement for AFDDs?


What is the safety case for the change? E.g impact on public safety, fires etc.Evidence?


What is the impact on the installation industry? How easy to fit, cost advantages disadvantages etc?


Will you feedback to the BSI on the changes and what will you say?

    Presumably, a 10 way CU from Wylex costs about £2000. This is a joke. A normal board with 2 RCDs costs around £100-120. The price has been multiplied by 20 times with the stroke of a pen! They also consume power at all times, lets say 1W, so an additional 10W load (10 way board) uses about 10 x 10000 kWh/year = 100 kWhr/year, about £17 too. This alleged fire protection is quite expensive, particularly as there is no evidence it will reduce fires at all. It will only cost £60 billion + 30 GWhr per year. Fantastic!
