Hello there everyone, I've dead tested some ring mains on a job recently but unfortunately I didn't do my measured end to ends. The circuits only have two spurs on each.
I have my R1 + R2's, it was wired in 4mm T and E so the earth is obviously 1.5mm.
For example, if one circuit measured 0.33 ohms, is there a calculation to work out r1, rn and r2.
Many thanks in advance.
