Also the cable is not rated for a standard 500 Vdc Megger insulation test.
Huh?, I never thought of that aspect of the voltage rating.
Now lets be real here, 230VAC is the RMS voltage of the supply we receive, the peak voltage is somewhat higher, that would be getting rather close to the maximum voltage rating of the cable, between cores.
This whole issue in my opinion is something being fixed that isn't even broken in the first place.
