Explanation
To determine the correct fuse rating for the electric device, you can use the formula:
Fuse rating (in amperes) = Power rating (in watts) / Voltage rating (in volts)
In this case, the power rating is 2000 watts and the voltage rating is 250 volts. Plugging these values into the formula, we get:
Fuse rating = 2000 watts / 250 volts
Fuse rating = 8 amperes
Therefore, the correct fuse rating for the device would be 8 amperes.
