When were ring mains introduced in domestic housing?
I was watching an episode of Foyle's War recently. A woman living alone was plunged into darkness. She called up a male friend who came round and told her that the "ring main" had fused. He repaired the fuse with fuse wire. The episode was set in 1941! I believe ring mains with 13 amp sockets etc came in some time after the war had ended. The family home built 1939 had old style 5 amp and 15 amp three pin switched sockets. We moved to a new built house in 1954 which had the new ring main system.
Comments anyone?
