A ceramic or induction cooktop with a power of up to 3680 watts is suitable for a 1-phase connector. This type of electric cooktop can be connected to a standard socket that supplies 220 or 230 volts. The appliance includes a regular plug, also known as a 2-pin plug. 1-phase cooktops are less powerful than cooktops with a Perilex connector. It's also more likely that you blow your fuses when you connect multiple appliances to the same cooker circuit.
