The size of the breaker needed for an induction cooktop depends on its power requirements, which are usually measured in watts. To determine the appropriate breaker size, you'll need to know the cooktop's power rating.
As a general rule, you can use the following formula to calculate the breaker size:
Breaker Size (in amps) = Power Rating (in watts) / Voltage
Most induction cooktops operate at either 120 volts (V) or 240 volts (V), depending on their size and power output. Typical induction cooktops can range from around 1,200 watts for small units to over 3,500 watts for larger, more powerful models.
For example, let's say you have an induction cooktop with a power rating of 3,000 watts and it operates at 240 volts:
Breaker Size = 3000 watts / 240 volts ≈ 12.5 amps
In this case, you would need a 15-amp breaker, as breaker sizes typically come in standard increments (e.g., 15 amps, 20 amps, 30 amps).
It's essential to follow the manufacturer's specifications and recommendations when selecting the appropriate breaker size for your induction cooktop. Always consult the cooktop's user manual or consult with a qualified electrician to ensure the correct breaker size and safe installation. Additionally, local electrical codes may dictate specific requirements for cooktop installations.
