440.62 does not limit the size of a room air conditioner to 40 Amps or to 250 Volts.




BTW, even though it doesn't apply, 440-62 has remained basically unchanged since it was added in the 1975 Code.
(Before the addition of Article 440 in the 1971 NEC, the info for Room AC's was in "Appliances", Article 422(F) Provisions for Room Air Conditioners)
