Interesting diagrams Scott --Thanks.
We're seeing more of this sort of thing here as well with the increasing use of computers.
We don't have the bright orange recepts. to identify IG outlets, but some manufacturers have gone as far as introducing a "non-standard" plug and socket so that equipment can be wired with different plugs and nobody can connect to the wrong outlet.
The plugs are based on our normal 13A type, but use a different shape earth (ground) pin. The only problem is revealed in the "non-standard" part of the definition: Each manufacturer has changed the pin shape in a different way, so a MK plug won't fit a Crabtree outlet, for example.
