About 3 kilowatts. That's why the unusual-sounding rating of 13 amps was chosen - no portable domestic appliance that is plugged in is above 3 KW ; all high power appliances are permanently wired in, e.g. oven, shower.
Answer for USA, Canada and countries running a 60 Hertz supply service.In North America there are many appliances above 3 kW, dryer, range oven, hot water tank. These appliances all use 240 volts for their heating elements
Watts = amps x volts. 13 x 240 = 3120. 13 x 230 = 2990. The heater is probably a 3000 watt heater
because kilo mean 1000
then the kilo watt would be 2990 divided by 1000= 2.99
Yes you can run a 400 volt heater on 230 volts but you will not get the full wattage rating that the heater produces at 400 volts.
The fuse rating should be 5 amps
From a 120 Volt supply, the Amp rating is calculated as 2,000 Watts (which is 2kW) divided by 120 Volts = 16.7 Amps.
No, this should not be done. If the appliance is a heater it will operate over its given specified wattage. A 200 volt heater run off of 240 volt will have an output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. A 240 volt heater can be run off of a 200 volt supply but the wattage will be reduced. For example if the heater is 5000 watts at 200 volts, the current is I =W/E 5000/200 = 25 amps. The resistance of the heater is R = W/I (squared) =5000/25 x 25 (625) = 8 ohms. Applying 240 volts on the same heater whose resistance is 8 ohms results in this new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/8 = 7200 watts. This is 2200 watts higher than the manufacturer's safety rating. W = watts, I = amperage, R= resistance in ohms and E = voltage.
It means that, to operate at its rated power, the appliance must be provided with a 230-V supply.

No. You need a 3-phase supply that matches the voltage and current rating of your appliance.

It will work but not as efficient as the manufacturer designed it to. If motors are involved in the appliance they will run hotter as they will draw a higher amperage due to the lower voltage. Appliances with a wattage rating for heating elements will not reach their nameplate wattage rating.

Yes. The voltage is the same on each. The ma rating of the power supply is the current the supply can handle before burning up. So if your appliance is designed to work on an 800ma supply, an 850ma supply will do fine.

Yes you can, as long as they have the nearly the same output voltage it doesn't really matter. It is even more important to check three other things:* that the amperage (current) drawn by the appliance is not greater than the rated output amperage shown on the transformer's label or rating plate;* that the transformer or power supply unit produces an output that is the same kind as that required by the appliance. For instance, if the appliance requires a dc (direct current) supply it will not work on a power supply unit producing only ac (alternating current);* if the power supply produces a dc output, be sure to check that the polarity ("+" and "-") of the power supply plug's inner and outer connections matches exactly what the appliance requires. If they are the wrong way round the appliance may not work or could even be damaged.If you have them, it is best to check the rating plates of both the original power supply unit and the other one you are thinking of using, as well as the appliance's user handbook, to see exactly what voltage (ac or dc) and what amperage is required.
True power is expressed in watts, so the true power of your heater is its kilowatt rating at its rated voltage. Variations in voltage will result in variations in its power. Assuming its resistance remains roughly constant for variations in temperature, then True Power = V2/R.

It means that, to operate at its rated power, the appliance must be provided with a 230-V supply.
Its function is to supply electrical power via a plug that is plugged into it to supply an appliance.
