[QUOTE="SLIPSHOD & SLAPDASH, post: 130508, member: 16"] The correct answer is to test at both socket no3 & the single socket spur, as the cpc could be lost/broken at either. In this scenario it would be easier to link the line to the earth bar in the consumer unit and then test at both furthest ends. When you come to do any live tests such as the Zs then you test all outlets and record the highest reading, which should be the longest cable run away from the board. If you want to be clever and get extra points you could mention that the sockets should most likely have 30mA Rcd protection i [/QUOTE]
