THE 17TH EDITION BOARDS CAN BE VARIOUS CONFIGURATIONS
The dual rcd seems to be the type thats taking favour with most people
In the 16th one rcd covering the whole of the installation was a deviation because it did not allow discrimination between say the lights and sockets
The 17th regulations require rcd additional protection for mostly everything in a domestic dwelling unles its surface wired,so the double rcd is being touted with up lights on rcd with down sockets etc and other configurations as well
It seems to me that the single rcd covering the whole of the installation was never no major problem(In fact I have this in my own home and its never been a nuisance as far as tripping everything off causing mayhem is concerned)
The 17th requirement will be a problem when adding lights and such to existing installations
How many people will use a double rcd for discrimination then (not many I would think)
So why the option of one rcd is frowned on by many is not a big problem in my estimation
Additions will be provided with one rcd where necessary and no thought given to discrimination in these cases ,so why do we be so concerned for new installs
Bring back the one rcd over the whole of the installation if thats whats wanted I say
and forget this dual rcd game of picking which team the up lights are on
Things are being over complicated with little advantage being gained
I take so long to type these essays out I get logged out
Getting more and more annoyed with this function lately
