One main reason for some disharmony in electrical product standardization is the existence of national installation codes.  As mentioned earlier, as with standards, historically, every country has their own installation code, which is reflective of that country’s culture and practices.  Canada uses the Canadian Electrical Code, Part I, (CEC) published by the Canadian Standards Association (CSA). The US and Mexico use the National Electrical Code (NEC) published by the National Fire Protection Association (NFPA). These codes are developed by the respective accredited standards development organization, through a consensus based process, that includes participation by the electrical safety authorities in that country. This makes it difficult to move to a single harmonized code for North America. However, there is significant harmonization of the two North American codes along with participation in the International Electrotechnical Commission (IEC) installation code
