I have never TT'd a shed/garage I always just extend the earth from the house.

In the example of a shed/garage being supplied with SWA is the armour of the SWA earthed by the house (lets say TNCS) or by the earth rod?

Also, if the SWA is earthed by the TNCS then you have both TNCS and TT present in the garage CU. If the SWA is earthed by the TT then you have TNCS and TT present in the Main CU? Is that ok with regards potential difference between earthing systems?

ps... I realise you can extend the equipotential zone but I am just looking at a TT for a shed, this is because of the chance of an electric charging point being in the shed (as per my other thread).
