7. 3 kw INDUCTION HOB

[nicebutdim]

The bottom line is that a number of factors need to be taken into account in determining cable size and these would require knowledge no one here is in possession of. A quick visit from your electrician would provide the answer.

That’s your second opinion then.

When I was “on the tools” I hated customers who bought their own materials. Often it was just plain wrong, or some cheapo tat that wouldn’t last a week. Or it hadn’t arrived. All of these added to time on thd job, and cost the customer more ££.
On more than one occasion I’ve just walked out to another job.
Look, It’s a new circuit. You’ll need a registered electrician, he/she has trained for years, is competent and is assessed annually. Trust him/her, you won’t save any money.

Bc I am currently in Czechia
I do not trust these people at all.

I am not in west eu or US... So it's pain here. So many diletans and I can imagine how they are assessed :/

Surely it's a three-phase supply there rather than a large single phase supply? You really need someone familiar with Czech wiring regulations and practices.

@Risteard
i have electrian visit next week, i believe there is also 3-phase supply, do i have to ask him to setup it in 3-phase way? is that better then single phase supply with one big CB?

thanks

He said i have 1phase 25A CB, and he said that my induction 7.3kw should work with it... that these are modern and know how to regulate power....

but he suggested that i should go for 2x 25A CB setup.

Confused.

It would probably work fine on the single phase due to diversity if nothing else.
