As a European standard for industrial socket and plug, the BS4343 standard was first published on September 30th, 1968.
From then on, this standard was used especially the country of UK.
Now it is replaced by the standard of EN 60309-2:1992 and BS 4343:1992.
This standard mainly described the specification details for industrial plugs, sockets, and connectors. For example, the voltage of BS4343 socket and plug is not higher than 750V, and the frequency is lower than 500Hz.
