New single module AFDD RCBO

Sparkingchip:

I fitted a few Crabtree consumer units twenty years ago, but there were the two designs in use and even then you could not get replacement RCDs for the earlier versions. Plus I had to drive quite a long way to replace a couple of failed MCBs.


So I stopped using them and have not fitted a Crabtree CU since then, so after twenty years I need to be brought back on side.


I presume these are not actually made in the same factory by the same people as those old consumer units and devices of twenty years ago, so need to be considered as a completely different product designed to be installed in a similar way being plugged into the busbar.


I do wonder how much back compatibility there is?
