I think you may have difficulty finding guides that discuss European systems as a whole in anything but the broadest terms. Although there is a standard 220/380V system and certainly a gradual move toward what the EU calls "harmonization" of standards, each country still maintains its own methods at the moment. For example, France and Germany use different connectors, different circuit arrangements, etc.
I understand a similar variety exists in Africa due to former colonization (e.g. Algeria follows French standards, but Kenya follows British methods). I think the same goes for the Middle East (I know one or two countries there use British methods & fittings).
You may have to resort to searching for information under each individual country.
The German VDE standards organization publishes a large assortment of technical books, some in English, so you might try there as a starting point: http://www.vde-verlag.de
