The £1300 AFDD consumer unit

I wasn't successful in tracking down the surge withstand strength information on the internet. It would be ironic if the introduction of AFDDs required the addition of SPDs!

See [Table 443.2]. Equipment which goes in a 230/400V DB needs to be able to withstand 4kV transients. (Meters, including smart meters, have to withstand 6kV!) One assumes manufacturers design their AFDDs to match.

I'm not sure that it's safe to assume anything associated with AFDDs!

This would be a great opportunity for the manufacturers to post their data sheets WITH the impulse withstand voltage.

I did find a data sheet for a combined MCB, RCD, AFDD with a 4kV impulse withstand quoted (co is called Eti and the device is an KZS-AFDD). I couldn't find the price!
