For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.

What if the input power is 208 volts line to line two phase 8 amps to a heating element vs 110 volts 8 amps to a heating element How is watts calculated?
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts
What is the kilowatt output of an electric heater that has an ampere draw of 50 a and a voltage source of 208 volts?
The watts is the volts times the amps So 208 x 50 watts, or 10.4 kW.
How many amps is 3KW at 480 volts 208 between legs.?
If you have 208 between legs, you have 120 from each leg to neutral (208 divided by 1.73). Assuming a balanced load, this would be 1 KW per leg - 1000 divided by 120 = 8.33 amps per leg. Your question contradicts itself. If you have 208v, the answer above is correct, 8.33 amps. If you have 480v, you have 3.6 amps.
45 kva at 208 120 volts amp load?
To calculate the amperage load, use the formula: Amperage = Power (in watts) / (Voltage (in volts) * Power Factor). For a 45 kVA load at 208-120 volts, assuming a power factor of 1, the amperage would be approximately 173A.
How many amps in a mega amp?
One Megawatt = 1,000,000 watts. Watts = Volts x Amps or voltage x current. Hence if you know the voltage then Amps = 1,000,000 watts / Volts.

What size ground wire needed for 75 amps at 208 volts?
#8 copper

45 kva at 208 120 volts amp load?
To calculate the amperage load, use the formula: Amperage = Power (in watts) / (Voltage (in volts) * Power Factor). For a 45 kVA load at 208-120 volts, assuming a power factor of 1, the amperage would be approximately 173A.
How many amps in a mega amp?
One Megawatt = 1,000,000 watts. Watts = Volts x Amps or voltage x current. Hence if you know the voltage then Amps = 1,000,000 watts / Volts.
What is the Power dissipated allowed by a circuit breaker with 208 volts and 5 amps?
1,040 watts or 1.04 KW.
What is the current pulled by 7500 w at 208 v?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
How many amps does a 208 volt 3 phase 45 kw hot water heater draw?
To calculate the amperage, you can use the formula: Amps = (kW × 1000) / (√3 × Volts). Plugging in the values, we get: Amps = (45 × 1000) / (√3 × 208) ≈ 131.1 amps. So, the hot water heater would draw approximately 131.1 amps.
How many amps does 30KW strip heater draw at 208 volts 3PH?
To calculate the current draw, use the formula: Current (A) = Power (W) / (Voltage (V) * √3). Plugging in the values, we get Current = 30000W / (208V * √3) ≈ 78.7A. So, a 30KW strip heater operating at 208 volts 3-phase would draw approximately 78.7 amps.
How many hp is 208 cc motor?
I bought a 208 cc snowblower , how many horsepower is that ?
Single phase 220 volts 2.6 kW how many amps?
You cannot convert 2.6 kw to amps with that information only. In order to convert watts to amps, you also need to know either current or voltage. This is because watts is volts times amps, and volts is current times resistance
