Why do the IEC standards differ from the ANSI/IEEE standards, isnt lightning the same all over the world?
Yes, lightning, for all intents and purposes, is the same all over the world. The standards differed in some respects and overlap in others. In the United States, the adopted standards for TVSS manufacturers are the ANSI/IEEE C62.41 and ANSI/IEEE C62.45. These standards have been the basis for TVSS design and implementation for over twenty years, and have been successful in protecting electronics all over the world. A portion of the IEC standards use a waveform that many feel does not represent the surge environment in which surge protectors are utilized in.
