    Why does it try to give you the value of 16KA in the drop down box for prospective fault current. Has anybody else come across this or do they know the reason why? I always put my measured value in but still would like to know the reason they try to give you the above value.

    There is the real world and then there is the gospel according to st NICEIC.... heaven help anybody who is stuck in the church of NICEIC who questions the gospel and comes up with any sort of reasonable or sensible idea or opinion that differs. That would be heresy.

    Agree - I've forgotten all this now (if I ever really knew it) but I think the BS61439 sets this and DNO work to it and so our nice little boards handle faults faultlessly, in theory :)
    Can anyone clarify please?

    You'll find in the notes section it explicitly states that this should not be a measured value. That is why it defaults to 25kA/16kA.

    Annex ZB of BSEN 61439-3:2012 has a Deviation for the United Kingdom that states that distribution boards intended to be operated by ordinary persons with double pole isolation, normal protective devices and type tested for use with standard supply fuses should be able to withstand a specified test using a fault current of 16kA and not fall below certain levels of safety during and after the test e.g. not cause fire and not be significantly damaged or deformed.

    Therefore all UK consumer units should be designed to withstand a 16kA fault current and so this is the maximum level you can specify on the EIC.

    That is 16KA with the energy limiting of a 100A BS1361 / BS88 fuse between it and the supply.

    Yes so long as it has a standard supply fuse you should be OK, the test is with a 100A BS1361 / BS88 fuse.
