Earthing Rods for EV chargers

johnwicklover over 2 years ago

Why is earthing rod needed in a TN-C-S System but not required in a TNS system?

Could you have a earthing rod in a TNS system ?

Any pointers would be appreciated.

Thanks.

EVSE installers seem to think that Open-PEN Protection built into the EVSE is the means of dealing with all the issues, allowing them to get in and out of a job in the shortest possible time.

But voltage measurement as an alternative means of protection is not as straightforward as it may seem.
