This diagram provides guidance for checking the continuity of ring final circuit conductors for compliance with Regulation 612.2.2. This should be viewed as step two to the post: Checking the continuity of live and protective conductors. Ensure installation, or appropriate part of it, is securely isolated, and proved to be so, before proceeding. Cross-connect the incoming neutral conductor with the outgoing phase of the circuit, and vice versa. Measure the resistance phase…

This diagram from Megger will walk through the process of checking the continuity of live protective conductors for compliance with Regulation 612.2.2.   Ensure installation, or appropriate part of it, is securely isolated, and proved to be so, before proceeding. Measure resistance of each loop in turn of phase, neutral and circuit protective conductors and record measured data, r1, rn and r2 respectively. Where the CPC is the same cross-sectional area…
