Ground Connection

Always connect the Neutral at the service to Earth Ground. If ground is not provided by the electrical
service, a grounding stake must be installed nearby. The grounding stake must be connected to the
ground bar in the main breaker panel, and the Neutral must be connected to Ground at that point.
The cross sectional area of the power grid's protective earthing (PE) conductor shall have a cross-sec-
tional area not less than 10 mm
Note:
• Need to provide sufficient separation between TT system and the buried metalwork
connected to the supply PEN conductor.
• When installed in a TN systems, the supplying circuit shall not include a PEN
conductor(combined protective and neutral) .
• If the power grid belongs to TN-C-S system, the charger needs to be grounded
separately to into TT system. A PME earthing facility shall not be used as the means for
the protective conductor contact of a charging point located outdoors.
