A CAT 4, 600V INSTRUMENT IS *NOT* REQUIRED FOR LIVE MAINS *BUT* is acceptable as it exceeds the requirement. Are they simply using the word *WRONG* to highlight that it is simply overkill for the task but still acceptable or are they actually saying it is WRONG to use that instrument for this task.
