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.

What is 1 to the 480Th power?

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.

Will a step up transformer from 208 to 480 save on power bill?

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


What is the benefits of using 277 volt electrical equipment?

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.
