To calculate the amperage, you can use the formula A = W / V, where A is amperage, W is watts, and V is voltage. Thus, for 4800 watts at 220 volts, the amperage would be 21.82 amps.
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
Yes, a 30 amp double pole breaker would be suitable for a 4800 watt wall heater. Since watts equals volts multiplied by amps, this wall heater on a 240-volt circuit would draw 20 amps (4800 watts/240 volts), which is less than the 30 amp capacity of the breaker.
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
You need to know amps to answer this... Amps x Volts=watts
