Hello I have added 5 sockets to a double socket the double socket in the annexe has a 2.5 armoured cable added which goes down to the summer house before going in the summerhouse it runs. A water feature on an exterior fused switch then goes in to the summer house where the first socket works but the other 3 do not the last one ends there. Did I have to run a cable from the last one to the first one to have a ring?? Regards. E
