Installation (domestic) without Service Head

Martyn
Canvassing opinion...


We have an Installation without its own service head fed from a 50s/60s ryefied/MSDB style unit.


The Ryefield/MSDB is inturn fed from a 200A Tp&n supply head belonging to DNO. No visible issues other than supply to MSDB being unsheathed.


The MSDB has no key or tool to open, has direct access to 70mm lugged cables with door closed. 


With door open for fuse access there are no barriers, all removed and lost. 


Service cables are single insulated, tails to meters insulated & sheathed direct in to this unit. 


EICR for one of the supplied flats, does it pass or fail?

    . . . In any normal domestic install we assess the entire install from the intake, BS7671 starting at the load side of the head. . . 

     


    No, BS7671 begins at the outgoing (load side) of the meter, or the outgoing side of the isolator, where this is provided by the meter operator / DNO. 


    Regards,


    Alan.
