I've met several senior engineers and have an impression that most (if not all) of them are allergic to NEMA. They prefer IEC for electric motors, even they dislike to see the word "TEFC".
How about you? Do they regard NEMA as "old engineering school" ?

I guess I'm old school, because I've never had any trouble with NEMA (National Electric Manufacturers Association) standards. Of course they dislike the acronym TEFC. The EU boasts 19 different official languages, and TEFC is an American acronym standing for Totally Enclosed Fan Cooled. Why anyone would object to the design standards for that type of motor mystifies me.
If I were working in Europe, I would use the IEC standards as a matter of course, but IEC standards would have to be loose, indeed to apply to both Europe and the US (and possibly even Canada). NEMA works just fine in the US (and possibly Canada, although Canada has her CSA) and making them subordinate to the IEC would be both counterproductive and inappropriate.

What country? What electrical code? International trade??
