Appliance Wiring (wire and breaker size needed)

Guys, just checking to see if I have the right idea for my wires and breakers for my appliances. This is new construction so nothing is ran yet.

Here are links to the appliances:

For the cooktop, I'm thinking I need a 2 pole 40amp breaker with 8/3 romex?

For the oven, its a single oven, and a search on Home Depot of my model says it 4000w. So that would be a 2 pole 20 amp breaker with 12/3 romex?

Yes, and actually you would only need 12-2 for the oven; however if it was my house I would also install the oven with 8-3 for greatest flexibility with future replacement appliances. Just use a 20A breaker on the oven and cap off the white wire as it will be unused at this time. The house will last longer than the oven and you don't want to have to cut out drywall to pull new cable when it comes time for a new one.

Thanks for your reply ib. One question though, why do you only need 12-2, not 12-3wire for the oven, but the cooktop needs 8/3 still?

The cook top is 120/240. The oven is 240 only.
