Just dismantled an old Memera 2000 CU that we had replaced shortly after

I assume the MCBs are still ok and could be used on another CU if they
fit, but the three RCDs are weird. They are (probably) single-pole, and
appear to be piggy-backed onto a 16A, 20A, and 32A MCB (but not the 6A
lighting MCB). Maybe Adam or John can remember these. Are these devices
of any use at all? Is it in line with the Regs to replace a
previously-compliant MCB or RCD with an identical device which is not
compliant with the current Regs? Or are they only fit for recycling?


They make the MCBs into RCBOs?
