Meaning of the applicance wattage range 2000-2400W that is written on a tally
Does the nameplate also state a voltage tolerance range, such as 230-240V? Because that would make a difference in the wattage. In a load that is a fixed resistance, Power (watts) varies at the square of the voltage change. So if the kettle is rated for 2000W at 230V, but you apply 240V, the new voltage is 240/220 = 109%, so it will consume 1.09sq. the amount of power, so roughly 120% power, i.e. 2400W.
