    best practice continuity

    If doing end to end continuity testing on a radial circuit (2391 test board) is there a requirement to carry out R1+R2 as well, and if so what does it prove? I carried out end to end on the board today as some of the circuit used armour as CPC etc and I was told I should have tested R1+ R2 as...

    Question regarding Continuity of Ring Final circuit.

    Can we carry out the continuity test for the ring final by connecting the line, neutral, and cpc end to end at any socket or do we have to identify and disconnect the conductors at the C/U? I am aksing as i think it is much easier to link the line, neutral, and cpc end to end at any socket...
