A 13 Amp fuse (brown) is needed for a 3kw heater. <<>> Answer for USA, Canada and countries running a 60 Hz power supply service. 3000 watts at 120 volts = 25 amps, 3000 watts at 240 volts = 12.5 amps.

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 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.

A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.

For a 3KW motor with a 350-meter run and 240V supply voltage, you would typically need a cable size of around 16mmยฒ for proper voltage drop considerations and to prevent overheating. It's recommended to consult with a qualified electrician or use a voltage drop calculator to determine the exact cable size needed for your specific installation.

Assuming no other factors are considered, a 3kW geyser would draw approximately 13 amps of current on a standard 230V electrical supply. This calculation is based on the formula: Power (in watts) = Voltage (in volts) x Current (in amps).

Assuming 100% efficiency, it would take approximately 6.7 hours to heat 500 liters of water with a 3kW element. However, in reality, the heating process may take longer due to factors like heat loss and initial water temperature.

To find the energy transformed in 1 second, we first convert the power from kilowatts to watts: 3kW = 3000W. Then we use the formula Energy (Joules) = Power (Watts) * Time (seconds). Substituting the values, we get Energy = 3000W * 1s = 3000 Joules.

To answer this question a voltage must be stated.

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.
