It does not looks much but it took most of the day to fit the 16mm cabling in the distribution board then make the final connection at the temporary supply.
16mm is difficult to work with because it is not at all flexible. So I had to estimate the length including bends to avoid other cabling behind, pre-bend it then feed it in before screwing it in tight.
All done by late afternoon and I now have power and powered lights inside the house.
