Have the rules for ring mains changed over the years?

So flex is dangerous? Not sure the cpc 'detects' anything.

Flex demands different requirements and it's clear you were refering to UK flat profiles.

I didn't say any cable was 'dangerous', I said it was less safe and more expensive. No strawmen please.

The cpc is used to carry fault current, which may be to do with an appliance and not the cable's insulation.

Yes, I know.

You can't strawman by asking a question.

You can when it misrepresents the argument but each to their own.

the sole purpose is to detect a breach of the dielectric barrier within the run of cable

Mainline : The cpc is used to carry fault current, which may be to do with an appliance and not the cable's insulation.

Yes, I know.

Then why post such a statement if you knew it was wrong.

We're encouraged to split between floor levels

By whom? I've always considered grouping power circuits into floor levels to be bad practice. Excluding rooms such as kitchens and utility, I've always grouped power circuits into rooms and those above or below them.

Like a ring upstairs and one downstairs

Bad practice, in my opinion. I wire a downstairs room with the rooms above it. Uses less cable and allows power upstairs and down even if a circuit is out of operation. Tht power may not be in the room you require it, but it won't be far away.
