@drscriptt So technically, the way the electrician set this all up works, except for the breaker.

The wire is 2x 2.5mm² between the stovetop and the breaker in the picture, that should be enough for the 30A load between the two conductors. But it doesn't make sense to configure it this way, unless I'm missing something, since the three breakers are there, ready for use. Why not split the load and prevent the breaker from tripping when all cookers are on? :floofWoozy:
