Sizing breaker size for a range/oven

[Cartoon1]

I have a range spec sheet that says 40Amp rating for a 208V. But then it also says rated 12KW. How do you typically size the breaker?

This is not a continuous load: so typically i do 40AMP breaker with a #8 copper. Should i increase the breaker to 50AMP with a #8 copper?

Below is the range link im looking at

GE Profile™ 30" Smart Slide-In Electric Double Oven Convection Fingerprint Resistant Range|^|PS960YPFS

You look at Table 220.55 Note 4 which says "It shall be permissible to calculate the branch-circuit load for one range in accordance with Table 220.55." Any range from 8-12 kW nameplate is a load of 8 kW per the first row of Column C.

8 kW @ 208V = 38A, so a 40A OCPD with 38A ampacity conductor suffices.

If you're using #8 NM cable then the 50 amp OCPD is not an option.

Small range (kitchen, house, etc.), 40a and #8; large range, 50a and #6.

Thanks. MC cable.

Thanks. MC cable.

#8 MC is good for 50 amps.
