At a steady state (when up and running) Watts = Volts x Amps so you just need to solve the equation 75,000 / 400 = ?
However, you add the caveat "starting". If your application involves a motor, for example, the starting current will be higher than the steady state current. One rule of thumb says the starting current may be as high as 6 times the running current. This higher current starts high and then decreases as the motor comes up to speed.

Why do different components draw different currents?
Different components draw different currents because they have varying resistance values. Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance. Therefore, components with higher resistance will draw less current, while components with lower resistance will draw more current for the same voltage.
What is the maximum current draw for an appliance that has 240 volts and 2160 watts on name plate?
To find the maximum current draw, use the formula: current (A) = power (W) ÷ voltage (V). In this case, 2160 watts ÷ 240 volts = 9 amps. Therefore, the appliance can draw a maximum current of 9 amps.
120v how much current does a 1500w resistace heater draw?
Using the formula Power = Voltage x Current, we can calculate the current: Current = Power / Voltage. Plugging in the values, we get 1500W / 120V = 12.5A. So, a 1500W resistance heater would draw 12.5A of current at 120V.
How long would an 8 Amp hr battery last with 75mA current draw?
An 8 Amp hr battery would last approximately 106.67 hours with a 75mA current draw. This is calculated by dividing the battery capacity (in Amp hours) by the current draw (in mA) and converting the result to hours.
What current will a 100w electric fan motor draw when you plug it into a 240v wall socket?
To calculate the current drawn by the 100W electric fan motor when plugged into a 240V socket, you can use the formula: Current (A) = Power (W) / Voltage (V). Therefore, Current = 100W / 240V = 0.42 Amperes. So, the motor will draw approximately 0.42A of current.
Which is better for starting star or delta?
The star configuration has less current draw across the line when starting.
Is it possible to start a motor with starting current of 50 Ampere in a supply of 26 ampere?
Yes. Circuit breakers are designed to accommodate for a short-lived current spike. The motor does not draw high current for long at starting and hence it's possible.
When testing for current draw your digital multimeter should be set on?
When testing the current draw your digital multimeter should be set on the current.
How do you calculate starting current of 380 volts 3phase 50 hertz AC motor?
Dear Sir,I want to know that how much draw starting current of 380 volts 3 phase 50 hertz AC motors as per rating values?
What would be the cause of high current starter draw?
decribe two causes of higher than normal starter current draw
Why does a toaster draw a lot of current?
all electric heaters draw a lot of current (voltage times current = watts [or power]) and a toaster heats bread (no it toasts Bread)
How it is getting current from generator?
To draw current from a generator, you need to connect a load to it.
What would cause a fuse to blow by the battery of a Dodge Neon?
Either a short to ground, or too much current draw in that circuit.Either a short to ground, or too much current draw in that circuit.
Typical current draw for a refrigerator?
My 20 year old upright freezer is about 10A starting, 3.27 amp running (263 watts) My 10 year old fridge is very similar
How much current does a 120v 1200w hair dryer draw?
Using the formula Power = Voltage x Current, you can rearrange to solve for current: Current = Power / Voltage. Plugging in the values, the hair dryer would draw 10 amps of current (1200W / 120V).
Why do different components draw different currents?
Different components draw different currents because they have varying resistance values. Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance. Therefore, components with higher resistance will draw less current, while components with lower resistance will draw more current for the same voltage.
What is the effect of starting torque and power factor on double cage and deep bar cage 3phase induction motor?
In double cage and deep bar the tarting torque increases due to skin effect in the rotor wire. So the rotor circuit draw less current than simple circuit that draw around 7-8 times the rated current on starting. Due to skin effect the rotor resistance increases and it provide maximum torque at low speed.
