Suppose someone from Europe moves to the USA and brings most of his electronic equipment designed for 230V. Assume this equipment won't mind 60Hz instead of 50Hz, but needs the 220V. Would it be a code violation if he uses a few European style outlets (with the seal of approval or listing from the European equivalent of UL) installed in his house, fed by a 220V circuit equipped with a double pole 15A breaker in the panel? Or should he use a NEMA 6-15 (If I recall correctly, 220V @ 15A socket) and change the plug on a European outlet strip that he can plug his equipment into?
