The default setting is 20 amps.
If your not sure if the electrician has set the power rating correctly you can easily go in and change it, as per the install guide.
Power on the hob without any pans on it, straight away set all hobs to level 1 for 20A, level 2 for 16A or level 3 for 13A.
Using the - button start with the bottom right hob, and set it to 0, followed by far right, then far left, finally set the bottom left to 0, the current should now be shown on the display eg "A/2" and "A/0" for 20A.
Press the power button on the hob and the setting should be saved.
Please let me know if you need anything clarified.
I just wanted to follow up and check if you required any further assistance, and request you rate the service received so I may resolve this case.
