picked up a Megger LT7 for peanuts the other day. so thought would try it, check it against 1552. plugged into outside socket ( feeds water feature) no trip loop test-- >50v.
Uh-Oh. isolated at MCB, opened socket, snapped off cpc at terminal due to stress caused by limited space in enclosure. reconnected, power on- Zs=1.0ohms. coffee time. just goes to show the importance of regular testing.
