EICR Certification DNO Fuse

Chivers
What are peoples thoughts on completing Certificates with regards to DNO fuses.


When you complete a Certificate Technically you do not remove the DNO Cut out fuse so you do not know 100% what the Fuse size is so would you personally put the fuse down as a 1362 type 2 and note down the rating advised by the Supplier or put this down as a Limitation? Up to this week I had normally put the rating as Written on the Fuse carrier by the DNO so 100A = 100A , 80a = 80a etc... I test the ZE/ZS at the closest place to the Suppliers cut out & note this down as the EFLI.


A colleague of mine has recently been "critical" of this stating we should be putting it down as a limitation as we can not guarantee the fuse is exactly what it says on the carrier.

    Couldn't you just write "≤100A" - we should be able to deduce that much at least (and you probably do need that much if you're relying on Annexe ZB of BS EN 61439).


    (BTW an EICR isn't a certificate)
