Another consumer unit contemplation. What's the best solution?
Been asked to replace 3 old Wylex fuseboxes at a 2 bed flat. Economy 7 supply, TNC-S earthing. Tails are 2xtwin and earth, probably 16mm (tbc). The meter box is in the communal area in its own meter cupboard. The fuseboxes are in the flat hallway by the front door, right up close to the ceiling.
First board, 4 way rewireable fuses on the off peak supply.
3 x 15A radials for one storage heater each.
1 Spare. (labelled as Immersion, must've been moved some time ago)
Second board, 4 way rewireable fuses on the standard supply.
15A radial for 2 x 3kw immersion heaters (via Horstmann Electronic 7 to ensure only one can be live at a time).
5A radial for lighting
30A ring for sockets
30A radial for cooker
Thirdly is a single 40A MCB for the shower (not sure what power rating yet).
There's no RCD protection on anything, there is some evidence of bonding but think it's 6mm not 10mm.
I'm looking for the most cost effective/ simplest/ easiest to install consumer unit solution.
Either two matching boards, or a 'dual tariff' one? or another idea?
Looking forward to your wisdom and experience. Thank you.
