SteveFor 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 ÷ 230V ≈ 13A). Always consult the manufacturer's recommendations and a qualified electrician to ensure the proper fuse size for your specific heater.

What is the fuse rating for a kettle?
A standard 3kW immersion heater will require a fuse rating of 13 A. This is because, it draws a current of 12 A.
What protective device should in the consumer unit be rated for a 3KW immersion heater use?
For a 3kW immersion heater, a protective device such as a circuit breaker or fuse should be rated at least 13 amps to safely handle the load. This is calculated by dividing the power (3000 watts) by the voltage (usually 230V in residential settings). It is important to ensure the protective device is properly sized to prevent overheating and potential hazards.
What is the cable size for a 3KW motor 350 meter run for cable 240v?
For a 3KW motor with a 350-meter run and 240V supply voltage, you would typically need a cable size of around 16mm² 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.
How many amps does 3kW geyser draw?
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).
How long to heat 500 liter water with 3kw element?
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.
