Protective conductor terminal must be connected to the cubicle or station protective grounding
system. Electrical codes and standards require that protective ground cables are green/yellow
conductors with a cross section area of at least 2.5 mm
connected to the station grounding system. Use a conductor with a core cross section area of at
least 4 mm
