BNO Connection Issues

gibb01
Hi - I'm new Here! Although I've been lurking for a while...I've had a Job today that has managed to Irk me enough to see if anyone else has had this issue.  We've been asked to carry out the works for a new supply to 3n. Flats & 1n. House - All of which are existing. (Long story - but they've all been connected via a communal supply from a commercial building for some time)  The new UKPN supply terminates into a standard 100A 3 phase head inside a kiosk. We've then installed a 5 way Ryefield board, From here Tails go out awaiting the meter connection & then onto 100A Switch Fuse isolators & then out in SWA's to each property. We've done this plenty of times & have never had an issue.

However....

The meter company (SSE) Attended site today & the installer stated he was unable to connect as we haven't installed Henley Red Link Fuses. I've never seen these before & after a quick google - they look like a normal surface mounted 100A cutout. I suggested that this was really no different from the Ryefield board & In fact that would then mean 3 100A fuses in series within the same kiosk within around 300mm of each other. However, He wouldn't have it & still refused to connect. This resulted in a very unhappy customer Who  may have to pay for an aborted visit (Unless I can prove there should be no reason for no connection)  & us having to temporarily connect back up all the cables we had disconnected...

Am I missing something - Or is this just an overzealous (& Perhaps underexperienced) installer?

To me - Cutout to Ryefield board to Meter to SW Fuses isolator is perfectly acceptable. 

Anyone's thoughts would be welcome

    The DNO, in this case SSE, have installed a 3 phase head. The DNO will not energise their supply unless the building network is complete if there is no (as in this case) MS/MSF. The building network from there is BS7671 requirements, up to a red head link/neutral block correctly terminated. on a meter board to which a suppliers meter and isolation switch will be fitted.by the Meter operator.


    All cables and ancillary equipment between the intake position and individual premises are installed in common access areas within the building and not through the property of another customer or third party. 


    While a PME connection can be available at the intake position if appropriate, the avoidance of neutral current diversion within a property is essential Therefore the building network shall be designed as separate neutral and earth network.


    Hope this helps,
