A small number of customers have had difficulties with Electricians who have insisted that RCDs must be fitted instead of the standard isolator switch when installing dedicated Hi-Fi consumer units and ring mains.
What's worrying on that page is that I believe it might encourage some people to just replace a main RCD with a D.P. switch regardless.
I agree with the the point made about misinterpretation of the RCD requirements, but how about homes on a TT supply which absolutely
need RCD protection on all circuits to provide proper protection against ground faults?
And what on earth is the point in suggesting a dedicated
ring circuit to feed
one outlet? Two sets of 2.5 conductors to one point? You might just as well run a radial with 6mm cable if you really want to keep the impedance of the circuit as low as possible.
