Hello friends,
i have been doing EICR for caravan sometimes now. On 16A or 32A hookup box with 30maRCD protection mostly found 1ohms or more Zs at hookup and more inside the van. When you put the results in schedule of test sheet which will not comply with maximum Zs value table from regs book. If you compare with amendment 3 now it gonna be even worst. When you get Zs value at hookup box 1 ohm or more on TNS earthing system ,inside the van your ring main Zs reading won't comply if you compare with regs Maximum Zs value table 1.1 ohms amendment 3 or 1.15ohms before amendment @ 80%. I have giving satisfactory EICR if I find low Cpc continuity and high insulation resistance of all circuits and in reference with 1667 ohms maximum Zs allow if you have 30ma RCD protection. I just want your opinion guys please.
