You can use either. I assume the 240 volts is the line to neutral voltage, and the 415 is the line to line voltages. They will both give you the correct answer. It is important to note these values are RMS, not 0 - peak voltages, but this may be beyond your question. The equations below are for calculated from RMS values (both voltage and current).
If you are using a L-L voltage, P = I*V*sqrt(3)
If you are using the L-N voltage, 1-phase power P = I*V (for the power in a single phase, for all three, multiply by 3), or 3phase power P = 3*I*V
You will get the same answer, since the L-N voltage is (1/sqr(3)) times the L-L voltage.
To calculate kilovolt-amps (kVA) when kilowatts (kW) is known, you can use the formula: kVA = kW / power factor. The power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical circuit.
The equation to calculate force when mass is known is F = ma, where F is the force, m is the mass, and a is the acceleration. If the acceleration is due to gravity, the equation becomes F = mg, where g is the acceleration due to gravity (approximately 9.81 m/s^2 on Earth).
When you have multiple circuits connected to a site, the entire circuit is known as a "distribution circuit" or a "feeder circuit." These circuits distribute electricity from a central source to various points of use within the site.
The last four parameters of the Drake equation (fl, fi, fc, and L) are not known.
The sum of currents in a circuit is known as total current, which is the combined flow of all individual currents passing through the circuit components. This total current is conserved in a series circuit where it remains constant throughout the circuit.
The equation for calculating velocity when acceleration and time are known is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.

the ABACUS. it is also known as the 1st calculating device created by the Chinese. it is also known as the 1st computer.
The equation is acceleration = net force / mass. This formula describes Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
If a dynamo puts out 100,000 kilowatts and the area it services only requires 80,000 kilowatts; then the remaining 20,000 kilowatts is known as its residual power. This extra capacity is useful in withstanding power spikes when consumer demand increases during peak periods.
This is what is known as a "short circuit".
In a series circuit, the voltage is the same across all components connected in a series. This is known as the series circuit voltage.
Calculating clock is the first known calculating device made by Wilhelm Schickard. This machine can perform the basic mathematical operation, but canÕt show too large result which is limited to six digits.
virtual circuit
This type of circuit is known as a parallel circuit.
