odd problem - when the ring main loaded up (e.g 2kW kettle or similar), the L-N voltage coming into the CU drops to circa 170V.

Anyone ever seen something similar to this ? Right now I can only think it's a high Z issue on the supply side, or very soon after it before it reaches the main switch in the CU.

It's been going on for a long time however, so wherever those watts are going, they aren't enough to further degrade wherever it is.

problem solved - loose connection at the meter :)
