How you convert the value of single phase power to value of 3 phase power?
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
How do you calculate full load in single phase circuit?
The question has to be more specific. Full load amps, watts or voltage. Please restate your question.
What is the amperage for a 20000 volt-amp heating unit on a 240 volt single phase circuit?
Volt amps is the same way of saying watts. This is seen in the formula Watts = Volts x Amps. Using the formula I = W/E we transpose I = 20000/240 = 83.33 amps.
What is circuit breaker rating when electric load of a machine is 11.5 kW?
This question cannot be answered as asked. you would need to know also the voltage and phasing. Assuming we are dealing with 120-volt, single phase, 11,500 watts would be 55-running amps. Assuming we are dealing 208-volts, three phase, 11,500 watts would be 32 running amps and assuming we are dealing with 250-volt three phase, 11,500 watts would be 26.5 running amps. I hope I have answered your question.
What type of induction motor used in ceilinf fan?
Could be a single phase induction motor of 20-40 watts.
How do you calculate watts to amps?
The most basic calculation is volts multiplied by amps of a circuit for a single phase load.
How you convert the value of single phase power to value of 3 phase power?
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.

How many amps does a 2000 watt heater draw at 240 volts on each line?
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
A 100 amp 3 phase power supply is good for how many total amps?
100 amps to a 3 phase load. Power = 100A x Voltage x 1.73 ((line to line voltage)(1.73=SQRT(3)). 173 amps to each of 3 single phase (line to line) loads. Power = 173A x Voltage (line to line voltage). or... 100 amps to each of 3 single phase (line to neutral) load. Power = 300A x Voltage (line to neutral voltage). Example: - 3 phase, 480v, 100amp to a 3 phase heater. 100A x 480V x 1.73 = 83040 watts. - 3 single phase 480v (L-L voltage) heaters, 100amp. 173A x 480V = 83040 watts. - 3 single phase 277v (L-N voltage) heaters, 100amp. 300A x 277V = 83100 watts.
How many amps is 6kW 240 volt single phase?
The equation that you are looking for is Amps = Watts/Volts. There are 6000 watts in 6kW.
How many watts is 4.75 amp refrigerator starting watts?
To convert amperage to watts, you need to know the voltage, power factor, and the number of phases that you are working with. For a residential refrigerator this is single phase, an industrial refrigerator could be three phase.
Why neutral wire carry no current?
Usually yes, sometimes no. For instance: The neutral in a single-phase, 120V (in the US) branch circuit, such as one feeding receptacles, does. The neutral in a 120/240V circuit feeding a 240V appliance does not. The neutral in a 480Y feeder feeding a balanced load does not. A neutral is there because of the possibility that current flow could occur. For instance, in a US household, with 120/240V service, if you plugged in 5 100 watt lamps on one side of the line, and another 5 100 watt lamps on the other hot leg, there would be no neutral current in the service cable feeding the house. The loads are said to be 'balanced'. The 500 watts of power flowing into the first hot leg goes through the first set of lamps, then the second set, then out the other hot wire. Neutral current still flows in the individual branch circuits, of course. Now, if you moved one of the lamps to the other side, 600 watts would be coming into that side, but only 400 would be going back out the other hot wire, so 200 watts would flow through the neutral.

Is converting ac to watts and dc to watts the same watts equals volts times amps?
Yes, watts is still volts times amps, for both ac and dc circuits. The complexity lies in the phase angle between voltage and current. If the circuit is purely resistive, the phase angle will be zero. If the circuit is capacitive or inductive, the the phase angle will vary, depending on frequency and on how much capacitive or inductive reactance there is. The difference comes into play when you consider true versus apparent power.
If a 240v circuit hsa 30 amps per phase what is the amperage 30 or 60?
Still 30 amps, but at 240 V you'll have twice the watts that you would on a 120 V, 30 amp circuit, and after all, watts are what actually does the work.
