Customers would like the option to label two halves of the board differently e.g. DB1L and DB1P (L for lighting, P for power) so that the two halves of the board have their own identity. It will also require the ability to select the number of ways on both halves of the board.
Consumer units are very close to what we need for split metered boards. It just needs to be three phase ways and enable the user to name each section accordingly rather than section 1 / 2. Numbering of the ways on the board will need to be laid out correctly too (or give the user the choice).
Adding similar functional to Switchboard Sections may be sufficient. Each Section may need it's own user interface as they would potentially be separate pan assemblies.
