Cable to outbuilding

[Mac]

Macca . the outbuilding is remote from the existing main building.....be it 1m. or 100m. therfore if it is to utilize the existing fault protection of EEBAD [ADS],then the equipotential zone extends to the outbuilding which means 10mm2 bonds to any extraneous conductive parts whithin it. Alternatively the outbuilding can form its own equipotential zone by creating aTT system.............if no extraneous conductive parts then no problem !

So what you're saying is,if you had a shed in your back garden with an existing supply already feeding a socket,you would still spike the shed.

If there where extraneous conductive parts insidethe shed and the supply cable was less than 10mm ,on a tncs supply,then i would probably run in a 10mm2 seperate bonding conductor from the M.E.T in the house....if this was not easily done then yes i would TT the shed........if no extraneous conductive parts then the problem does not exist.....The o.p doesnt say either way on this issue
