Can a residential range (in a dwelling unit) receptacle be connected to a 40A circuit breaker with wiring sized for 40A? The range used is less than 40A. The range literature says 40A circuit breaker. The receptacle will be 50A.
Is there anything that says that the 50A receptacle needs to be connected to a 50A circuit?





This does not affect the sizing of feeders and service. I am asking what is required (not what should be done).

I agree-- sounds good. The minimum size for a range 8 3/4 kw or more is 40 amps-- 210.19(A)(3). Look at T. 210.21 (B)(3)
