Sure, that's what I meant, and thought I had expresed clearly. I decided against using 'to/from' in favour of 'between', since I though that made it clearer that I wasn't not meaning to imply anything about direction, but I seem to have failedOr vice versa.it must be flowing between the incoming neutral and your main bonding (i.e. to incoming water pipe etc.)
OK, but if it gets worse when the fuse in in and the load is increased, that implies than an appreciable part of the return path for your loads is via the earthhing conductor rather than the N conductor (until they join at the cutout) - which could only really be due to something very wrong within your installation - which I thought we had established is not the case.sorry, to be clear, it's there when the dno fuse is in, and seems to be effected by load. It is also there, but nowhere near as bad, with the dno fuse out (ie, It's like an 'idling' current).
Very odd. Logic seems to suggest that if an increased load on your installation results in a substantial increase in current (rather than tiny increases die to leakage currents) in the earthing conductor, then the return path from those loads must be at least partially via the 'earthing' (CPC) wiring - which makes no sense, given your 'clean' PIR.OK, I'm confused too, I can see your point but this also happens in other property's so I don't know how this happens! but yes, it was FULLY investigated with the PIR, then an extended look at the entire house tracing each cable from start to end. Floor boards up, loft checked all over and nothing could be found by either of the two (and I must say very experienced) electricians sent out.
No, not 'the forum' - only those forum members who have participated in this threadRE: the film/book - I suppose this forum is entitled to a cut of the profits? lol
Indeed, but surely they should know, not be speculating, whether there is such a broken/high resistance neutral - and if they know it's there, should have identified by now where (or, at the very least, roughly where) that fault exists?I think the clue came from an earlier comment by Andrew that one of the SP guys mentioned a broken (possibly high resistance) neutral. If this is between him and the transformer some of the current from customer loads could use the numerous parallel paths via customer bonding as a return path for the load current (and any fault current if there is a fault on a customer's wiring somewhere)
