Hi went to a job yesterday there was 3 ring mains so i thought, after testing them they were radials but were all terminated into 32 a mcbs 2 wire in them did R1 R2 TESTS and readings were high 3.2 ohms/ 1.9ohms these were the highest there are a further 4 radials which are around the 1.9 the house is a barn conversion
so the runs are quite long the system is TT and the zs is around 70 ohms on most sockets will this be acceptable not quite sure what to do here, just need some advice please.
