Earthing question

The question is; would this be the same for TT as well as TN systems? 
Yes.
But don't say positive - thats for DC supples - positive an negative.
We use live and neutal, and so say something is live, or say it has a potential difference of 240v etc.
Neutral to earth should be near to zero, but may have a few volts hanging on it due to volt drop in the neutral etc.
