Great attitude issue ...see you getting a lot of repeat business with responses like that.. Not!
We are professionals, our opinions are derived for the Regulations as simple as, the 2 question I asked were very relevant and would have totally changed my answer.. if this was a new install I would have said its poor design best to re-run the supplies in SWA or Mechanically protecting the T&E so as to drop the need for RCD up front, If this is an existing set-up then you don't have to bring it up to the 17th but either way having 2 x 30mA in series is a no go and on any new install this should not ever be the case.
To call us reg book shaggers is a clear statement you are somewhat less than professional, anyone who was genuine would be interested in what area of the regs and where they stood with regard to their question, your response suggests you see anyone competent to use the regs as some sort of jobsworth well maybe its a reflection on yourself not been up to the mark.
You stick to what you think you know, why bother with regs... the fact you asked the question means you don't fully understand them and yes thats why we are here to advise but sorry your attitude stinks, you don't like the responses you got so dummy was spat like an immature excuse for a professional tradesman .... Enjoy your short stay in the forum if you keep it up with the attitude!
