Hi,I just wonder if how many of you would test a 4mm ring for ring continuity .The reason I ask is that a chap I work with testing has said a lot of sub contractors don't test 4mm ring as it can carry 32amps if the ring was broken.i my self have always tested ring regardless of conductor size, would be good to see what you think
