"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.
Ouch! I can feel my knuckles being rapped for putting one in so that I might use an electric hedge trimmer more safely. In fact, I know that one should put the flex over the shoulder i.o.t. reduce the risk of slicing through the cable, and even if I did slice through it, I wouldn't be daft enough to pick up the live end. Sadly it's all a bit academic 'cos box blight seems to be killing the wee hedges. ?
Let's not forget that short of Part P, there is no obligation to install to BS 7671. Thanks largely to this forum, I think that I am in a good position to decide when to depart.
