Help needed here, where can i buy affordable built in oven? Any dealer or shop i can go? What brand is good with budget of 1500 - 2500?

Hi experts.. Recently I've just purchased a oven Fotile model KQD50F-C2 and a electric hob model EEG75201. My wiring contractor was asking me the power points requirement on oven and hob. I read the specification of these models but it didn't specify the requirement for oven. Only stated for the electric hob is to be connected directly to 25A circuit breaker.

Then I called up the Fotile support service centre hotline for clarification. A very helpful and friendly technician says 15A for the oven and 20A for my electric hob would be sufficient. For the oven no issues but I questioned him that his advice on 20A power requirement for electric hod is contradict with their brochures which stated 25A. Then he says 25A also can.. I asked my wiring contractor, he says 25A is super big power! It makes me more confused

Appreciate if anyone here can advice me should I go for 20A or 25A for the 4.5kW power requirement. Thanks in advance!
