Whirpool ACM 816 BA Induction Hob: Short Circuit and Fuse Blow on First Use - Possible Causes?

Hello,
I have a problem with the induction hob, first the electrician connected the plate to the three-phase residual current circuit breaker (AC type), the switch immediately knocked out.
Questions:
1. Does the difference have to be A or B or it doesn't matter?
2. The hob, after connecting without a differential, turned on, but after switching on the field with the pot, it sparkled and the overload fuse broke, and after turning on the eska again, the plate sparkled, and immediately blown the fuse as if there was a short circuit.

The hob is connected by a qualified electrician according to the diagram in the manual (bridges etc.) Could the quality of the pot (type) have an influence on the situation? There are no signs of short circuit on the terminals under the board. Does anyone have any idea what could be the reason?

It was probably connected wrongly, unfortunately it happens very often.

Knowing from experience, the board was connected to three phases, it should be two.

To be sure, attach the diagram as it was connected.

I am sending a diagram and photos of the test connection, according to the figure, 3 phases, earth electrode and bridge on neutral.
PS. Can anyone comment on the subject of differences?

Attachments are added in the previous post, please comment. An electrician says to call the service that the board is damaged?
PS.
What kind of differential to use?
best regards

How did the fault end because I have the same problem ??

Hello.
Is someone able to describe the solution to the problem?
I have exactly the same symptoms - after connecting, it throws out the protection.
When connected to 230 (no matter on which phase) the board does not respond.
best regards
