I'm working on a property with a tncs supply which has the dno cut out in an outbuilding about 20 metres away from the house. They have had a boiler installed in said outbuilding which is connected from the main house via some swa for electrical controls and insulated pvc pipe for the water.House is supplied from 100A enclosed main switch in outbuilding has dual rcd board and the tncs earth has been exported to house.Now the outbuilding also has sockets and lighting installed which are not rcd protected.Do i need to put the ccts in the outbuilding on an rcd? Is it ok to export the tncs in this way?
