Over the last few days I have been stuck indoors because of the rainy weather. To pass the time I cobbled together my simple idea for a FRC live conductor break detector, ie break in L or N. I also have a working demonstrator for detecting a break in the cpc but I will/may post that another time. The quality of filming is not great but you should be able to make out an LN into a double pole 30mA RCD (bottom middle) and then the left and right legs each supplied by a 32A 30mA DP RCBO and fed from the RCD. The lamp holders represent FRC sockets and the lamps loads. The top switch plate breaks the N and the middle left switch plate breaks the L. Only the 2 RCBOs trip - the RCD remains set.

It is a technology idea using off the shelf components but of course not approved for use in actual installations. It has some flaws which you might want to think about and how you would fix them.

I repeat, it is just an idea which might be the basis of a new commercial product. Someone no doubt has thought of something similar already but I am not aware of anything; I don't then claim to be the first to think of this technology.
