Check out Annex B of En61000-4-6 on the cut-off frequency (lambda/4) for short cables. Referring to the figure, <316mm is so short that the entire test is non-applicable.
Installation instructions (and/or a dedicated cable) assure installers do not splice in more cable length.

Several of the leads are not really long enough to make it through the FTB capacitive coupling clamp. Any thoughts on how to test these lines? 1) Extending them just for this test 2) Using what length there is 3) Not testing at all.... Insight appreciated, Derek Walton ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
