An outbuilding is fed from a separate single way board in the house and has a 2c 4mm SWA to the building of 7m. Its a TNS. This outbuilding has its own water main (albeit in plastic) which comes directly from the water meter not through the house. Testing between copper pipes below the sink and the SWA earth gives 400Ohms
Given that Main protective bonding should be continuous and 6mm, am I correct in thinking that strictly speaking I should make this TT, or would anyone bond the pipes to the local CU earth terminal?
