Make sure to use the code for the socket, not for the plug; some combinations have a measure of cross-compatibility, and you don't want to mix that up in the tagging for the socket. A few examples: the UK, Ireland, Malta, Singapore (at least) use Type G, in France/Belgium it is type F, in the Netherlands it is type E.

Looks good to me, except that the tag name should really be something
like "power_supply:socket_type" rather than the over-generic
"power_supply". I am please to see that frequency and voltage are
covered, as is maximum current. Not sure polyphase supplies are fully
covered though. Only one socket type is described as 3-phase; there is
at least one other type, and that also seems to accommodate USA
split-phase as well:

There is also this tagging scheme for the same thing:

Now how did that happen???????
