While global harmonization could be a good thing, I wouldn’t hold my breath in expectation for it to happen anytime soon, even for North America. While the electrical systems in Canada and the US are similar, many of our standards in Canada are much different than those of our American neighbors’. Regulations even differ from province to province. With these differences, I would think that it would be virtually impossible to come to an agreement on who’s standards are best and which ones to adopt into a common Electrical Code.
Just my 2¢ worth.
