3 wire 3 phase ungrounded systems

Former Community Member

I suspect I already know the answer but are 3 phase, 230 volt, 3 wire ungrounded systems permitted in a UK installation?


I know this is common practice in some parts of the world but it's not something I've come across in the UK.


Just for clarity this would entail a delta connected secondary with 230 V between phases requiring separate earth fault detection.


I wait with abated breath.

    What equipment is this circuit intended for, I presume it is a piece of imported equipment that serves a very specific function for which there isn’t a UK alternative?
