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.

    Thank you Chivers for asking this question. The BS7671, Requirements for electrical installations, as its name suggests has no bearing on ESQCR Distribution/Suppliers works. For some years now the guide book has tried to associate itself with the legal paper but of course any reports/certificates (EICR/EIC) can only ever be of a visual nature. If by chance you through your experience you notice exposed terminations, overheated wiring, tampering, its best to contact the local DNO who will attend as an emergency, or ask your customer to make the call. In answer to your question the term N/V (not verified) is suitable.
