The delivery guy says to run my oven and tops for 30 minutes to burn off the factory chemicals.
I did. Turned on my oven to 400, set the timer for 30 min. Then I turned the burners on HI. My breaker tripped.
I'm perplexed as this is a replacement oven. I previously had a 220 for a cooktop and a seperate 220 for a double oven on an opposite wall, the cooktop was in an island. Was told the 220 for the cooktop could be used.
It is...straight from the wire....

The breaker will have an amperage listed on it. Say it is a 30 amp breaker - 30 amps x 220 volts = 6,600 watts. The instruction manual for the stove will have the wattages of all the burners and the stove element. Add those together and I'm almost certain it will be more than the rating of the breaker.
Your choices are to have the circuit rewired and a new larger breaker installed, or to not use all the burners and oven at once. I'd have it rewired, myself, so I wouldn't have to rely on the breaker if I did something dumb.
You're not going to be able to use both at the same time. 10/3 means it's a 30 amp circuit, of which the connected device shouldn't be pulling more than 24 amps (80%). Most ranges need more power than that at full load.
You're going to have to rewire - at least 8/3, which is suitable for 50 amps (40 amps working), and replace the circuit breaker. DO NOT even think about just replacing the breaker alone ... that'd be a fire hazard waiting to happen.
The breaker box shows what you had said....the one I tried to use from the cooktop was "30". ...this other one that went to the double wall oven says "50"....they both are like two breakers together.
6/3 - that's suitable for 65 amps, 52 amps working.
edit: new post came as I was typing this up ... yep, use the 50amp wall-oven circuit for the range.
I'm assuming you are applying the 80% rule which is wrong. The 80% loading of a breaker is only a rule on continuous loads and a oven/range is not a continuous load defined by the NEC. The range will not pull maximum current for 3 hours or more.
You need to read ampacity tables 310.16 in the NEC. With 6/3 NM cable you are limited to the 60 C column because of NEC 334.80 and 6/3 copper is 55 amps.
FYI - These electrical appliances come with installation instructions. Those instructions will tell you the amperage required for the specific appliance!
Best to read instructions like these before installing. (You can actually damage some things by not connecting them to the proper power supply - the warranty will also be voided if you do so.)
