Connecting Multiple Bemco/Ryefield Boards

GHEC
Ok I have a new build project where one Bemco/Ryefield board is not large enough to cover all apartments. 


I will need to install 3 to cover the number of outgoing ways required.


My questions is this. Given that there is one incoming bulk supply, what options are there to split it between the three? I know Lucy do an MSDB with a vertical busbar. Would the DNO accept daisy chaining these together? Or should we use a busbar chamber and tap-off to each board?


Any advice would be gratefully received.

    I suspect the answer to your questions from the DNO are “no” and “no”. It should be done properly, with one DNO feed to each Ryefield, each fed from a separate fuseway on the DNOs fuse rack in the substation.
