Hi all, I haven't done domestics for a while and have been asked to install an 18th edition CCU to a small terraced house ( 2 floors Ground and first). I been told that I need to install a SPD? Can someone confirm this is the case and are there any exceptions. Haven't done my 18th but will be doing so shortly. I found this from crab tree, option 3 appears to give the installer some discretion?
Regards peter
