For a 3kW heater, you would typically need a 13 amp fuse. This is calculated by dividing the wattage of the heater by the voltage of your power supply (3,000W รท 230V โ‰ˆ 13A). Always consult the manufacturer's recommendations and a qualified electrician to ensure the proper fuse size for your specific heater.

A 3000 Watts heater typically uses a 13 Amp fuse in its socket. 13 Amps is an accepted fuse rating because it can allow high power usage but will be secure enough to cut out any over-voltage that can damage an item.

How do you size a fuse?

To size a fuse, you need to consider the maximum current that your circuit will draw. The fuse should have a current rating slightly higher than this maximum expected current to provide protection without nuisance tripping. The voltage rating of the fuse should also match the circuit voltage.

What would be the resistance of and the current drawn by a 3kw 240 v immersion heater?

Power = E2 / RResistance = E2 / power = (240)2 / 3,000 = 19.2 ohmsCurrent = E / R = 240 / 19.2 = 12.5 amperes
