Thanks all. I was just checking to see if anything had changed after the long discussions about this subject in the past. I intend to place a 100mA S type R.C.D. before a new metal cased consumer unit on a TT earthed installation.
Could the S type not go in the CU as per section 2.2.6 of the OSG?
Yes, that seems to be the common way, but if an isolator is going to be installed in a (domestic) TT installation, then why would you not use an RCD "main switch" instead of an ordinary one in your REC2 (or similar) enclosure? The you can stop worrying about your tails flapping about or getting chaffed - as if that could happen when competently installed!
