How fuse should be used in a 2.8kW kettle?

To determine the appropriate fuse rating for a 2.8kW kettle, you need to calculate the current it will draw. Using Ohm's law (I = P/V), where I is current in amps, P is power in watts, and V is voltage in volts, we can calculate the current:

I = P/V = 2800W / 230V = 12.17A

Next, you need to select a fuse that can safely handle the current drawn by the kettle. It's recommended to use a fuse with a rating slightly higher than the calculated current to provide some margin of safety. A fuse rating of 13 amps (13A) would be appropriate for a 2.8kW kettle.

Here's a breakdown of the selection process:

1. Calculate the current drawn by the kettle: I = P/V = 2800W / 230V = 12.17A

2. Choose a fuse rating slightly higher than the calculated current: 13A

When selecting a fuse, it's important to use the correct type of fuse for the application. In this case, you should use a BS 1362 fuse, which is commonly used in UK plug fuses. Always refer to the manufacturer's instructions and safety guidelines for your specific kettle and electrical system.
