Re: Another unusual plug and some other questions
Tractorfan, G6Tanuki, AC/HL (220, 221, 222)...
Many thanks for the suggestions. Our landlord in the 1950s was never anxious to modernise - we still had Victorian fireplaces and a cast iron cooking range when we left the house in 1969 - and he had family links to both coal mining and railways, so an industrial origin for the plugs and sockets sounds very likely.
The sockets were star wired back to one of two cast metal quadrant lever boxes above the kitchen sink (the other being for lighting). The sockets had no earth provision, despite the fastening screw on the plug case, which 'captured' the appliance earth wire.
I will now investigate industrial connectors!
