Chris Pearson:UKPN:
"Begs the question, what the actual purpose of a BS 7288 SCRD is now."To provide additional protection for a particular socket in an installation that pre-dates routine RCD fitment in the CU and which is otherwise sound and a change of CU is not desired.
Except that BS 7288 is not recognised by the 18th Edition in Regulation 531.3.4.1. So, in either an addition or alteration, or a new circuit, a BS 7288 socket-outlet can provide neither additional protection nor fault protection without a departure. And with the current Edition of BS 7288 saying what it does in the introduction, effectively additional protection and fault protection should be provided upstream in accordance with BS 7671, it's arguably difficult to justify that departure.
