All electrical equipment, regardless of the voltage, should have a voltage supply that is no more than plus or minus 5 per cent of the equipments stated voltage requirement.
It depends on your definition of efficiency. 480 can certainly push more power than 208 through the same size conductors, but it would not be efficient to wire a motor for 480 when 208 was all that was needed.
A 350 kVA transformer operating at 480 volts would draw approximately 416.67 amps of current. This is calculated using the formula: Current (I) = Power (kVA) × 1000 / Voltage (V). Thus, I = 350 kVA × 1000 / 480 V, which results in around 729.17 amps. However, it's important to note that this value assumes a power factor of 1; if the power factor is less than 1, the current draw would be higher.
On farms, the most commonly used voltage for general electrical needs is typically 120/240 volts for residential areas and 480 volts for three-phase power used in larger agricultural equipment and machinery. Some farms may also use higher voltages, such as 600 volts, for specific applications. The choice of voltage depends on the size of the farm and the type of equipment used. Additionally, some farms may have specialized systems, such as solar or wind power, which can vary in voltage.
A 480 v three-phase system has 480 v between live lines and 277 v from each line to the neutral. This type of supply is common in North America for supplying for example small factories that need more power than a 120/208 v three-phase system can supply.
Current in 200kw at 480 volts = 200,000/480 = 416.667 amps

640 x 480
It ranges from about 900F to 860F (about 480°C to 460°C) at the surface.
No, SJ cord is only rated for 300 volts and is not suitable for use with 480 volts. It is important to use the correct voltage rated cord for safety and to prevent damage to equipment. Look for cords that are specifically rated for 480 volts.
50.375^480 = 1.1567203912184184319807171792746454876653658310532 x 10^817
The 757's cruising speed ranges from 460 to 480 Knots
To calculate the time taken to perform work with a certain amount of power, you can use the formula: time = work / power. In this case, the time taken to perform 480 Joules of work with 20 watts of power would be 480 J / 20 W = 24 seconds.
1 to the power of 480 is equal to 1. This is because you are multiplying 1x1 480 times. Thus, 1 to the power of ANY number will always be equal to 1.
The frequency of a busy tone typically ranges from 480 Hz to 620 Hz.

No, you are billed for the energy used so in principle the voltage does not affect the cost. The equipment used is designed for a set voltage and cannot be used on a different voltage. The reason to choose 480 v instead of 208 v would be based on the size of the site, and if there are distances of more than 300 ft involved in the power supply it might be economical to start with a 480 v system. The choices are between 120/208 v and 277/480 v so that using the higher voltage will require the installation of 277 v lighting
with 3 phase lighting you do not have to use as large of wire and can use one neutral for every 3 current carrying conductors so it cut down on material costs ( as voltage increases current decreases) <<>> The voltage 277 is the star-point voltage of a 480 volt three phase system. By using a 480 volt wye system you have the dual ability of running 480 volt three phase equipment along with 277 volt lighting. The side advantage is the ability of using the phase voltage to ground (neutral) 480 / 1.73 = 277 volts for general lighting of the building the 480 volt equipment is located in.
