[QUOTE="SLIPSHOD & SLAPDASH, post: 258488, member: 16"] Another well done from me. I dropped a clanger yesterday whilst testing a new job. The job has been running nearly two years now, huge house with 3 phase supply and 2, 24 way boards Cables were meggered and i did R2 wander lead testing ages ago but now most circuits were on i thought i would go round with the young lad and do a complete set of tests. I linked L to E at a board I was getting 201 ohm R1+R2 ( did more tests and found same results on quite a few circuits). I spent ages looking for a bad Cpc, thought about feed through neutral and general head scratching for over an hour and a half. Then it hit me, 3 phase board and i had only linked one phase to earth :Blushing :Blushing:Blushing [/QUOTE]
