[QUOTE="Phoenix, post: 473279, member: 8133"] I would be hesitant in using N/A for the L-N insulation resistance, as clearly the parameter of LN insulation is applicable to the circuit , what isn't applicable is the requirement to test it in those situations. In my head I consider N/V more to do with a quanity which is inspected, rather than tested, e.g. the supplier's fuse size, carrier says 80A on it, so it goes down as "80 (N/V)", I suppose I could use N/T (not tested) for items where the test is not required or even "---" as per the R2 box which is not needed when R1+R2 is provided. It just goes against the grain marking it as N/A when clearly it is applicable but I see what you are saying, LIM suggests its a required test but it was excluded for some reason, when what we are trying to say is "Test not relevant/required for the works carried out" Might make myself a note to discuss this one with the NICEIC chap in a few months when he does his annual visit in a few months time [/QUOTE]
