Hi Jean,
The context behind wanting to know about the 3-phase infrastructure is just to know the limitations of putting renewable energy onto the island. Single Phase power and SWER lines limit how much power can be supplied to the grid unlike 3-phase power.
I couldn’t quite make out the street view photos on google maps to be able to tell the size of the fuse boxes attached to the buildings.
I’ll definitely look up at that previous thread and the document you mentioned as well.
Thank you for answering my questions. 🙂
