[QUOTE="avinalarf, post: 19690, member: 631"] Evening folks Been going over (& over) testing and did an IR test on my downstairs ring and got the following reading which concerned me somewhat; line to neutral = 0.67! Neutral to CPC was 175 megohms and line to CPC was 143 megohms. I'm assuming that these readings indicate a breakdown of insulation, but can anyone suggest why the line - neutral is so much lower??? Also, is there some way which I can detect exactly which part of the ring may be most affected? Many thanks [/QUOTE]
