decades Greece had a 3-pin
type of earthed plug and socket, named Tripoliki
which means three-pole. Late 1980s Greece authorities have decided to
switch to CEE 7/3-7/4 (Schuko) standard for earthed plugs and
The museum has a Tripoliki plug, but a matching socket is missing.
Occasionally Tripoliki sockets can be found in some older houses in Greece.
Please contact me if you have an out-of-service socket, or a socket that you
like to replace by a Schuko socket.
The image shows the outlet of a Tripoliki - Schuko adapter.
|a - d||The
Bakelite plug and connector with two angled, flat power pins and a
round earth pin have been identified as late 1930s models, made by
Vynckier Frères & Co. in Gent, Belgium. They are now shown on the Belgian heavy duty page (see nos. 17-20).
|e||An uncommon T-slot connector plug rated at
10A - 250V that has been made in England.
The museum has a few T-slot sockets and plugs, but they are incompatible with the shown connector. The critical difference is the slot spacing (9.9 mm for the connector).
Classic U.S. T-slot spacing is 13.8 mm. NEMA 2-20R has a larger slot spacing: 15.9 mm.
Non-earthed T-slot plugs and sockets are used In Australia for extra low voltage. They have a slot spacing of 15.2 mm.
The significance of the T-slot model made in England is not clear. Was meant for export to …?, or was it an adapter plug for …?
If you recognize the English T-slot model, please contact me; find the address at the home page.
