An object that throws off only 480 volts of electricity is no more powerful than a static electric shock from carpet in winter. Tasers can shoot out probes that are 20,000 volts or more.

A voltage level of 480 volts is the working three phase service voltage of commercial and industrial sites in the United States. The service is usually a wye connection so that the star point voltage of 277 can be used for building lighting.

In Canada the three phase system voltage for commercial and industrial is 347/600 volts

How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?

220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.


How do you get single phase 440 from three phase 440?

You Don't. 440volt 3-phase is actually 480 volts, taking a single phase gives 277Volts single phase. To get single phase 440 you would use one leg of three phase 440/760 three phase power.


Should 2 legs of 480 volt 3 phase each have 480 volts?

Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.


Can you run single phase 230 from one side of 480 volt 3 phase?

No, you will not obtain 230 volts. From a wye connected three phase 480 volt supply, 277 volts can be obtained from one phase leg and the neutral on the wye connection. 480 volts/1.73 (sq. root of 3) = 277 volts.

What is the amps of a 5.5 kw 480 volt 3 phase?

Current in 200kw at 480 volts = 200,000/480 = 416.667 amps


Do you need a neutral to install 480 volts 3 phase heater?

If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.


Wiring diagram to convert a 3 phase 480 volt generator to 277 volt?

You should not need a wiring diagram. If the generator has a star point (wye) connection then the phase voltage to ground (star point) is 277 volts. 480/1.73 = 277.


What is the difference between 277 volts and 240 volts?

These voltages are both wye connection three phase voltages. The voltage difference comes from the primary three phase voltage supplies. 277 volts is obtained from 277 x 1.73 = 480 and 240 volts is obtained from 240 x 1.73 = 415. 480/277 volts is a common three phase American voltage. 415/240 volts is a European voltage. In Canada a common three phase voltage is 347/600. The 240 volts could also be a single phase voltage in North America derived from a split phase secondary on a distribution transformer that supplies 120/240 volts to homes.


Does a 480 volt panel have a neutral bus?

Usually yes. A typical 480 volt panel is a 3 phase panel with 480 volts line-to-line and 277 volts line-to-neutral. However, I did once see a panel that was 480 volts, 3 phase, but because it served only motors it did not have a neutral. (a 3 phase motor doesn't use a neutral.) Similarly, if a panel uses only 2 legs of a 3 phase 480 volt system, which would be called single phase, it would not require a neutral if it only feeds 480 volt single phase loads. But I find the idea of no neutral to be extremely unusual and in my one personal experience, I blamed it on the age of the system. In 16 years of commercial and industrial construction I have never installed a 3 phase panel without a neutral and all my work is designed by engineers.


What voltage reading would you get from a 277 480 volt system?

From a three phase four wire distribution system the voltages would be as follows. From L1 to N - 277 volts. From L2 to N - 277 volts. From L3 to N - 277 volts. From L1 to L2 - 480 volts. From L2 to L3 - 480 volts. From L3 to L1 -480 volts.


How do you come up with 277 volts?

The star point or wye voltage of a 480 volt three phase four wire system is 277 volts. The 480 voltage is divided by the sq root of 3 (for 3 phases). The sq root of 3 is 1.73. 480 volts/1.73 = 277 volts. The same formula is used on all three phase four wire systems. 208 volts /1.73 = 120 volts, 416 volts /1.73 = 240 volts, 600 volts / 1.73 = 347 volts.
