I’m using a Tesla wall connector, with intelligent octopus go. I have been having an issue where the pen fault detector has been tripping out, after about 30 mins to about 2 hours after it started to charge off peak. This has been going on for months. The electrician has ran test and can not find anything wrong, all through this I have changed to a new model 3 and had another wallconnector replacement from Tesla, and it is still happening. Anyone else experience anything like this and ideas of how to help.
