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.
What else can I help you with?
What will happen if 120 volt appliance is plugged into 220 volt outlet explain with electrical equiation?
If the supply voltage is Vs and the equipment voltage is Va, then the equipment will work if Va = Vs (equation). But if Vs / Va = 220 / 120 (equation) the equipment will fail.
What is a sentence using the word volt?
The unit of electrical potential is the volt. The volt was named for the Italian physicist Alessandro Volta.
Can 220 volt be the source at the panel and 120 volt out from the panel?
No, the source voltage can not change to a lower voltage without using equipment to do so.
How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
Is a grove rt 58c crane 12 volt or 24 volt electrical system?
The Grove RT58C crane typically comes equipped with a 12-volt electrical system.
What equipment is needed for testing electrical current?
For measuring electrical Current the electrical equipment used is Amphere meter. This equipment tells the current flow in the equipment.
What will happen if 120 volt appliance is plugged into 220 volt outlet explain with electrical equiation?

What types of test equipment does Fluke offer?
Fluke offers electrical testers and electrical test equipment to name a couple. They even carry voltage detectors and volt alert. On their website they even offer demos and videos.
What is the unit of electrical voltage?
The Volt
Do I need an adapter for electrical in Australia?
If your equipment is from North America then yes you will need an adapter as the Australians use a 230 volt system.
Will using 240 volts ac 60 cycle damage 240 volt 50 cycle equipment?
It shouldn't damage the equipment. But it will probably not work properly.
Will 120 volt equipment work on a 110 volt transformer?
Yes.
What happens when 220 volt equipment is plugged into a 110 volt source or if 110 120 volt equipment is plugged into a 60 volt source assuming all alternating current?
temporary it blows or KABOOOMM....
How can I install a 110 receptacle alongside a 220 receptacle using the 220 receptacle wires for power?
While you can physically do this it violates the Electrical Code. 110 Volt and 220 Volt receptacles are required by the Electrical Code to be on separate breakers for safety reasons, this would put them on the same 220 Volt breaker.
Can you charge a 12 volt battery with a 14 volt alternator?
Yes. It is done all the time in automotive electrical systems. The alternator, which creates AC, has its current rectified using diodes.
