    Called to carry out live tests & certify

    I was called by the client to do final live test & issue EIC. Not so straight forward, not all cable chases have been plastered and a couple of areas where boarding has still to be completed. So annoying, anybody else come across this?

    Continuity Tests

    Is the continuity test for circuit protective conductors, the same test for ring and radial circuits or is there a different test for each type of circuit? Also what is the difference between testing for cpc continuity and testing for continuity for ring final circuit conductors?
