24 amps. This could be three 11.54 resistors connected in star, or three 34.6 ohm resistors connected in delta.
The electrical code states that a 30 HP induction motor at 460 volts three phase will draw 40 amps. <<>> I = 33.34 AMPS IF EFF.= 95% AND P.F.= 85%

There is one part of the question missing. To find an answer the kW of the heater must be stated. Then the equations used are, to change kW to watts, Kw/1000 = watts. Once that is found then use, I = W/E, Amps = Watts/Volts. This will give you the value in amperage of the heater.
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
To calculate the amperage for a 10kW heater on a 3-phase 220V system, use the formula: Amps = (kW x 1000) / (√3 x Volts). So, Amps = (10 x 1000) / (√3 x 220) = 26.18 amps per phase. Therefore, the total current drawn by the heater is 26.18 amps per phase multiplied by 3, which equals approximately 78.54 amps.
To calculate the amperage drawn by the heater, you can use the formula: Amperage (A) = Power (W) / (Voltage (V) * Square root of 3). In this case, the amperage drawn will be approximately 5.8 Amps.
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.
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.
The formula you are looking for is I = W/E.
A block heater typically draws around 6 to 10 amps of current. It may vary depending on the wattage of the heater and the voltage of the electrical system it is connected to.

100 KW divided by 415 volts is 241 amperes. Power = voltage times current, so current = power divided by voltage.
For a 1hp 3-phase motor, the current draw will depend on the voltage supply. Typically, at 230V, a 1hp 3-phase motor will draw around 3.6 amps. However, this value may vary based on the motor efficiency and power factor.
To determine the amperage draw of a 5200 BTU heater, you can use the formula: Amps = BTUs / (Voltage x Efficiency). For example, if the heater operates at 120 volts and has an efficiency of about 100%, it would pull approximately 43.3 amps (5200 BTU / 120 volts). However, many small heaters operate at lower voltages (like 120V), so it's essential to check the specific heater's specifications for accurate amperage.
Assuming the power factor is 1, a 10 hp motor operating at 600 volts in a three-phase system would draw approximately 13.33 amps.
