45000 / 208 /sqrt(3) = 125A per phase
this is probably called a boiler unless it has a 2000Gallon tank

How many amps will a 3 phase 480 volt 4kw heater draw?
8,33 Amps
What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?
10 Amps. Amps=Watts/Volts
How many amps does a 50 gallon water heater with 2-4500 watt elements draw?
30
How many amps does a block heater draw?
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
How many amps does a 10kw heater draw that's 3phase 220volt?
40 amps
How many amps will a 3 phase 480 volt 4kw heater draw?
8,33 Amps
What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?
10 Amps. Amps=Watts/Volts
How many amps does a 1 phase heater draw if it run on 8kw?
To answer this question the voltage of the heater must be given. I = W/E.
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.
If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?
Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous
How many amps does a 50 gallon water heater with 2-4500 watt elements draw?
30
How many amps does a block heater draw?
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
How many amps does 30KW strip heater draw at 208 volts 3PH?
Assuming it is a 208-volt line voltage (as normal in 3-phase) the phase voltage is that divided by sqrt(3), or 120 volts. Each phase has to supply 10 kW so the current on each phase is 83.3 amps.
How many amps does a 10kw heater draw that's 3phase 220volt?
40 amps
Will a 10 hp 220 volt motor draw large amounts of electricity?
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
How many watts or amps draw on a GE water heater model se50m12aa01?
The GE water heater SE50M12AA01 is a 5500 watts or 5.5 Kilowatts water tank. The amperage on such a tank is I = W/E. Amps = Watts/Volts. Since most hot water tanks in North America use a voltage of 240, the amps will be 22.9 amps. It must be fed with a #10 conductor from a 30 amp breaker.
What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
