45-50 amps. But your overcurrent protection and wire must be designed for 125% of load so the max overcurrent protection is 55 amps or 60

The formula you are looking for is I = W/E. Amps = Watts/Volts.
you will need 21.81 amps at 220v
A 2000 watt heater draws 8.3 amps on a 240 v supply, so the cutout should be set to 10 or 12 amps. <<>> In North America a 2000 watt baseboard heater will be fed with a two pole 15 amp breaker. A two wire cable of #14 copper will be used to connect the supply voltage to the heater.
Pwer is volts times amperes. 120 volts times 10 amperes = 1.2 KW

First you need to find out how many amps the heater draws. Then use this formula: Volts (220) X Amps = Watts Then take: Watts x 3.41214 = Btu/hr
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts - but uses 12.5/6.3 amps
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Find the block heater and look for the nameplate on it. It will be in watts. Use the following equation to find the amperage that it draws. Amps = Watts/Volts. The voltage to use for the truck will be 12 volts.
The formula you are looking for is I = W/E. Amps = Watts/Volts. As you can see a voltage must be stated to answer this question. 10kW = 10000 watts.
you will need 21.81 amps at 220v
That load would be 10.9 amps.
A 220v heater has two 110v lines coming into it--either two 110v lines with a neutral, like a range, or two 110v lines with no neutral, like a water heater. Unless there's a fan in the system, they only use two wires. It's cheaper that way. If you have a DEDICATED circuit for each 220v heater--one where there's only one thing on the breaker--and you have at least 10/2 wire (unless the amps call for 8/2 or 6/2 wiring, which happens), you can install a two-pole breaker to feed 220v to the heater. If you're just trying to plug the heater into an outlet and get it to work, you've got a problem in that you can't pull 220v out of a 110v outlet no matter how hard you try. Sorry.

The amps it draws depends on how big it is. Typically 2-12 amps. Check for a manufacturer's plate that shows the wattage Most of the load in a rice cooker is a resistive heating element, so the amperage will be quite close to the wattage divided by the voltage (220 here).
