i followed 1 last month where he's put a code 1 for undersized tails, but completely missed the burnt and dangerous connection on the main switch incoming L. ( wylex rewireable board )
Yes, similar thing here, code 1 for 'undersized 16mm tails' yet he identified the suppliers fuse as a BS88 60A.
Seriously though, actually putting in writing that 'upgrading the tails will rectify the high Zs' is just amazing!!
