What's classifications for this grounding system ?
and do you think what's best surge arrester for my client with ground system like this ?
Is this TN-C or TN-C-S or something ?
For 220v 2a - 50a (Small to Medium house), ground wire and neutral wire is connected in KWH meter, also ground wire between kwh meter and LVMDP ground is usually not bonded, and neutral and ground connection only allowed at KWH meter
