Ran a lighting circuit, singles in conduit, this circuit has a decent Zs 0.7ohms
Owner then decided to put in another light which he wanted switching separately.
I ran in a new switch live and neutral, no earth as I was using the earth already in the conduit.
Now this circuit gives me a Zs of 2.3mohms, which is massive.
The earth is continuous and r1 + r2 is good
Any ideas
