Ah, I see. That's obviously very different from what Risteard suggested - namely that it was deliberately omitted from BS 7671 because hearsay had told him that BS 7288 forbade the use of devices to that Standard as providers of 'additional protection' unless there was another upstream RCD device.
Yes, maybe it's almost semantic - a BS 7288 device can obviously only provide 'additional protection' to things plugged into them, not to any of the actual circuit.
Agreed (and a lot are still in-service in such situations) - but what is your point?
I didn't know what sort of device BS7288 referred to until I looked it up.
That's what I suspected, and why I asked the question. In that case, as I said, such a device surely could be used to afford 'additional protection' to fixed wiring, couldn't it?
Factsay.
Which proves my point.
I'm not totally clear as to where the quote came from, but what on earth is meant by "....such as phase to neutral"?
That is clearly obvious - NO residual current device can provide any upstream protection. Perhaps it was someone misunderstanding a statement like this that resulted in things getting twisted to create the hearsay which Risteard's heard?The quote then said:
Perhaps. However, nothing in BS7671 indicates, or even suggests or implies, such a restricted meaning of 'additional protection' - so if that's what they meant/intended, they should have given away a clairvoyant with each copy of BS7671!
