[QUOTE="ADS, post: 130675, member: 7231"] As with a ring final, you prove polarity by doing R1 + RN followed by R1 + R2. There is nothing wrong with doing the exact same tests on a socket radial as you do on a ring final, and test at each socket. R1 + R2 on it's own doesn't prove polarity on a socket outlet,(even if you throw the switch), because you could have a Line - Earth reversal:D [/QUOTE]
