I have a ponderance.... When encountering a split load board that complied with the 16th edition, how is it possible to make it 17th compliant?
Rather than replace an entire consumer unit, I've been contemplating modifications. One existing situation has a MK Sentry 12 way board (100A Main Isolator, 80A RCD) with the busbar cut to make it 5 unprotected ways and 7 RCD protected ways (2 of which are spare).
To RCD protect all ways, one option is to fit 5 RCBOs, but this costs way more than a new board.
I could fit another 80A RCD to protect the first ways, so making it a dual rcd board. However this has no high integrity circuits, or indeed capacity for extra circuits.
I could fit another small board for extra circuits.
Or can I remove the 100A DP isolator and so free up another two ways? There's already a 100DP isolator in the tails from meter to board, clearly labelled, and only an arms length from the existing consumer unit too.
I asked MK technical and they couldn't grasp the concept.
Am I missing something or would this be compliant?
Ideally I would end up with
2xRCBOs, 1 x 80A RCD protecting 6 ways and another 80A RCD protecting the final 6 ways.
All advice, and any reg references, most gratefully recieved!
