    down sizing long lighting circuit

    I'm testing a car park lighting circuit at 200m long. 4mm singles to first point at about 100m and then reduces down to 2.5mm. Trunking used as additional CPC to reduce Zs values. How would you record that on a test sheet? And is there a regulation about downsizing?

    testing R1 + R2

    When testing R1 + R2 on a three phase circuit, do you connect each phase in turn to earth and test at other end? Record the highest value? Similar to what you test Zs on 3 phase but without the connecting? Cheers all.
