    I think the big change has been in cost. When RCDs first started being mainstream, they were expensive so a big incentive to only fit...

    As above, there are many light switches inside bathrooms. Most are fine. It really comes down to where it is in relation to the "wet...

    That's the sort of thing I had in mind. Users find that if one of the loads trips the breaker, the others go off. So some bright spark...

    Yes, it is indeed. The twist here is having 3 phases and (we assume) 3 poles on one MCB. Some might be tempted to swap out the 3pole MCB...

    Still allowed IF sharing protection (fuse). But since most dimmers I can recall tend to have a fuse on each output, that's not the case....

    Ooh, interesting one. I assume you mean you have a 3P circuit which you don't need to run anything 3P - so you stick (say) 3off BS1363...
