[QUOTE="Chrisbee, post: 545264, member: 34814"] My friend has just had a Growatt battery system added to his existing FIT PV system. The installers couldn't get the WiFi dongle to connect to his WiFi so he asked if I'd try (I failed). While there I noticed that the two CTs had each been clamped right around 3 core cables. See pics attached. Also one was on the AC connection of the battery inverter and I'm sure that one should be on the house incoming tails. We called the installers who are coming back on Monday. My question is, how should we expect the CTs to be attached to just one core in a run of T&E or 3 core flex? I'm thinking some sort of break out box, maybe with terminations (wago?) inside, along with space to attach the CT around just the live core. [ATTACH]15465[/ATTACH][ATTACH]15466[/ATTACH] [/QUOTE]
