I am not asking about the induction cooktop - I need to know about the wattage useage of the Bosch unit 500 seri3es.
I understand that. What your electrician told you is 100% correct. If all the burners are turned on at once, Watts (W) 7,700 W Current (A) 32 A Volts (V) 240/208 V Frequency (Hz) 60 Hz If you want individual burner wattages: (2) 7" 1800 W; (1) 400 W; (1) 6"/9" 1300/3100 W; (1) 6" 1200 W
Also, you asked how it compares to other cooktops, and it's right about average for the upper end electric glass cooktops. If you wanted one that consumed less power, you'd want one that doesn't have a bridge element between the left two burners. That's why it uses more power that the lower end ones.
Thank you - will it really require #3 wire?
