Fair enough. We do sometimes see people here being told that it is OK for the FCU of a fused spur to be a 'reasonable distance' from the origin of the spur (which is true in terms of protection of the cable against overcurrent) - but that is a situation in which the issue we've been discussing might possibly arise, if it's going to have to be an RCD FCU because of what is downstream of it.Ah, ok. ... I suppose I'm just used to doing it and not thinking there may be occasions when someone unfamiliar with the work may wrongly site an RCD FCU a long way from a socket necessitating needless discretion.
