Residential Cooktop and double oven Compliant? Practical?

[mbrooke]

I would like you all to weigh in I was recently asked if the following was compliant and or practical. I personally think it is compliant but not practical.
This is a remodel situation. Can you take the existing Range Feeder 6-3 w.ground and terminate it to a new Sub panel then feed two circuits one 40 amp to a 7.9 Kw cooktop and a 6.75 KW double oven.
I calculate as : 14.65 KW
subtract 12 KW from 14.65 = 2.650
2650 X 5% = 2782.5
8kw the min demand plus the amount over 12KW

8000 + 2782.5 = 10782.5
10782.5/ 240

44.93 amps

it looks ok but i feel it is impractical as this home owner entertains a lot. It will be difficult to run a new circuit as this is a condo and another unit below and concrete floor.
What do any of you think.

If you bump the breaker up to a 60amp I feel its ok, however that cook top is pushing it. But if your forced to do it, you can do it without worry.

But if we are still talking multioutlet circuits, 210.3 doesn't let us go over 50 amps.

Good point. I was assuming these were hard wired, but it appears to not matter. Easy to forget what can be done on industrial premises with supervision and what cannot.
