[QUOTE="toontoonizer, post: 504021, member: 33054"] Ah getting the hopes up and then down again 😁. I did another test to assess the voltage drop between the supply and annex. Checked the annex voltage with both multimeters to assess for differences in calibration - both meters showed the same voltage so differences were within margin of error. Put voltage probe on the supply live and neutral Henley blocks and a probe on the annex's consumer unit IN live and neutral. I measured 209v at the supply and 207v at the annex with a 40A load on the annex SWA only. Total load on the supply was 60A. So that's a 2v drop across the SWA run from the supply to the annex consumer unit. [/QUOTE]
