    Well, I could say with TNC-s you are never sure the potential the CPC will be, relative to earth.  ?

    However, in a self contained equipotential zone, just using the TNC-s Earth will be perfectly fine. As  TT island woudl also be fine as well.

    If it had an earth floor, or was going to supply an  EV charger or a radio shack then TT might be better.

    If using the TNCs earth, please earth the armour at both ends.
