Supplying garage with power

[Paul Willoughby]

Evening

I am supplying a garage which is 14 meters from the house (House is TNCS), I will be taking the supply from a non - RCD protected 32A MCB using 6mm SWA cable buried. I will not be exporting the earth, so will installing earth rod - TT at the Garage, protected with a 30ma RCD and 2 MCB's 6 & 16amp.

Is is this sufficient protection MCB & SWA or is RCD protection needed?

Where I am confused is the earthing connections from the house as I am not exporting the earth is my only earth connection for the circuit from the earth tag of the SWA.

Also in the garage, I have my earth from the rod connected and the terminal and the earth tag from the SWA.

I originally purchased 3 core SWA and was told I should connect the earth to the house and leave it disconnected at the shed.

Think I have over thought this job and I "cant see the wood from the trees", so hoping for some clarity.

Thanks
