Electrical – Stove and oven on same circuit


Does an induction stove and an electric oven need to be on separate circuits? If they can be on one, what amperage circuit breaker do they need?

My house has a different circuit for each one, 50 amp for oven, 40 amp for stove. They are on opposite walls, and I'm redesigning my kitchen and would like to place them next to each other. So, if I could use the same circuit it would be much, much easier than having someone come out to relocate the second outlet, since I think relocating that outlet is beyond my comfort zone.

I'm looking at the amps required for a induction stove/oven combo, and they mostly say 40 amps, but when I look at just an induction stovetop by itself, it says 40 amps, and the wall oven I'm looking at says 20 amps. Little confused why it totals to much more when they are separate appliances.

See table 220.55 in the NEC, as well as footnote 4 to that table:

  1. Branch-Circuit Load. It shall be permissible to calculate the branch-circuit load for one range in accordance with Table 220.55. The branch- circuit load for one wall-mounted oven or one counter-mounted cooking unit shall be the nameplate rating of the appliance. The branch-circuit load for a counter-mounted cooking unit and not more than two wall-mounted ovens. all supplied from a single branch circuit and located in the same room, shall be calculated by adding the nameplate rating of the individual appliances and treating this total as equivalent to one range.
