Metal Contactum board installed 1998 according to the labelling. Unfortunately it has a plastic flap covering the front of the devices. Anyone know if it's possible to cheaply get a new cover with a metal flap? Would be much easier than taking the whole board out, and seems silly to update all the innards and leave that one thing non-compliant with current regs.
If anyone cares why I'm updating the innards:
Currently has a 100A 30ma main switch with 11 circuits coming off it, RCD has been tripping lately, only when all the outside lights (on several circuits) and the inside lights are on together apparently, and then only intermittently. After testing and inspecting including taking apart everything outside to check it's not full of stuff and looking for any damaged cables, with no culprit I can find besides some low IR (but just about acceptable), I've put it down as combined leakage just tripping the RCD. Splitting it from 1 RCD to 11 RCBOs (with a normal MS) will either sort that, or if I'm wrong pinpoint the problem circuit, and of course mean they don't lose all power when something does trip!
