I would have thought that by far the most important reason for not fusing a neutral (whether alone, or also with a fused 'live') is the pretty obvious safety issue - that a neutral fuse can blow, making it appear that no power was getting to whatever was downstream of the fuse, even though there could still be a live feed to the load/whatever.
If there were an RCD.
Are you still talking about a fuse in the neutral? If so, that would not protect the live conductor in the cable from overload, in the event that there were an L-E fault and no RCD.
Only joking.Only if there were no additional paths to true earth after the CPC has been disconnected!I guess disconnecting the CPC would sort that.
I'm pleased to hear that!
Are there any that aren't?
Indeed - as I said, that appears to be one of the two main issues.
That's true, although as you can see my point of disagreement is on the importance, i wasn't trying to introduce a new reason.
Oh, fair enough. I certainly wouldn't argue about which is the 'more important', since I personally would say that they both are (important) - and I was therefore probably wrong to write what I did about relative importance.
Indeed - but I'm not sure of the relevance of that. As Andy himself added, even a single-pole one would break the 'live' (in response to an L-E fault), so I don't really understand what that has got to do with the discussion about a 'fused neutral' - what am I missing?
