oven/range amperage requirements

Yesterday I observed an oven and range - separate appliances – wall installed oven and counter top installed range wired with 8 AL protected by 30 AMP breakers.

I generally see 6 AL on 40-50 AMP breakers for these appliances.

As these were both installed flush – no manufacturer tags could be observed.

Are there appliances out there that have 30 AMP requirements?

Yes, I see it all the time, and I'm just down the road from you and Chad.

Good thing to remember is you can always use a smaller size breaker on a larger size conductor...as long as it properly fits the terminal lugs and so on. However in this case the # 8 AL is rated for ( 60 degrees ) 30A so in this case the wire size is correct for the OCPD....Now as stated we would need to know the KW of the appliances to finish the calculation...the safety aspect is you know 30A can be handled on that 8 AL....so even if the feeder to the cooking appliances was under sized the OCPD will protect the conductors......which is about all you can go on right now without the other factors.

Here is a nice calculator you can use if you ever find those values
