the following types of earthing connections are practiced:

TT>> Earth-Earth Connection

TN>> Earth- Neutral Connection

TN-C >> Earth-Neutral Combined

TN-C-S>> Earth-Neutral Combined Segregated

one moe thing is for telecommunication

 

TT is the best pacticed grounding system for the facotories

TN is normally used for residential bulding in may areas/countries

the other grounding systems are installed purposely; grounding system also depends also on GFCI (Ground Fault Current Interruption) or RCD (Residual Current Device) installation requirements.

but the safer and convenient is TT.

thanks
