UPDATE TO THE ABOVE POST:
I've found the Ze readings on the reports!
2015 report (current report) = 0.04Ω
2008 report (old report) = 0.23Ω
So... looking at the 2008 report.... 0.25 R1+R2 +0.23 Ze = 0.48 (calculated Zs). Zs per the report = 0.47. So virtually exactly the same, like you guys said. Although that might still indicate the 2008 electrician managed to get a "normal" Zs reading of some sort as the Zs figures aren't identical.
So, I think I will go back and ask the current electrician if there was a reason why he didn't use the alternative calculated Zs (ie do an R1+R2 reading) in the absence of a standard Zs reading.
Is there any issue with the differences between the two Ze readings? (the 2015 Ze reading seems quite low comparatively with the 2008 Ze reading)
This does also still leave the question about the low readings on the heating circuit insulation resistance (less than 1MΩ) so I'd be grateful if you would let me know "attention" this circuit might need, in your opinion?
Thanks guys, your help is much appreciated.
I think you are giving this spark a hard time lol.
