    As the title says, does a three-pin socket (external) used as charging point need an earth electrode or open PEN fault? Are mode 1 and mode 2 exempt from this ? I was under the impression that anything used as EV charging point and if located externally, the installation would need to have...

    A quick search for earth tape didn't come up with much, though this thread was of interest. I'll start by mentioning that I've led a sheltered life and only ever dealt with PME (TN-C-S) so never had to deal with earth rods. At our church, we've had an inspection of the lightning protection...
