[QUOTE="binky, post: 477509, member: 490"] so why do we have individual cct IR boxes to fill in on a standard test cert and no 'global value' box? When was the last time anyone sat down and calculated a global IR value? It's a question that is never raised on the forum becuase nobody does it, and if you are correct, how come this isssue has never been raised on any of my annual assessments? I think the wording of the big book is a little misleading, or has been worded to allow for global testing whether it is a good idea or not. Perhaps [USER=9512]@Sidewinder[/USER] could shed some light on this? If you consider how much cabling is in something like a shopping mall and used global IR testing, I suspect it would have an 'ice-cream in hell' chance of passing :^O I once fully rewired a house that had been rebuilt in 1947 after being bombed. It was wired in ViR, it passed all IR testing and I was surprised how supple the rubber still was, except where it gets a little warming in the back of sockets - try moving the cable and the insulation disintegrated. This is where experience and the opinion of the tester comes into play. There was no way I would pass it a safe for continued use even if the test results said it was OK [/QUOTE]
