Hi hope someone can help. The shed in the garden is about 15m away from the house. Its supply is spurred from kitchen ring via a 30Ma RCD/13A FCU, the load side of the FCU (2.5mm flex) runs outside and underground (within metal conduit) to an adaptable box where its joined to 2.5mm SWA which runs to the shed. At the shed the SWA is terminated into a 13A FCU, which supplys' 2 sockets and 2 strip lights.
Does this installation require a TT earth system as a matter of course. As it is now the earthing arrangement is via the CPC (including SWA). The house has TN-S system.
Thanks
