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
You would need to use a transformer. It would have to come from a three phase system. Residential homes are single phase electrical systems and the only what to get three phase 480 volts would be from a generator. This is a common question when someone gets a piece of equipment from a commercial or industrial setting where three phase electricity is commonplace. It is not practical to try to run a 480 Volt, 3 phase piece of equipment at home.
typically only high voltage commercial equipment uses multiple phase circuits (e.g. dryers, sheet metal benders, generators). more voltage means more current is possible which makes the other component requirements desirable
Yes you can and the logical approach would to use a step up three phase transformer. The primary voltage being 220 volts with an output of 480 from the secondary. The kVA rating of the transformer would be calculated on what the connected load current or connected load wattage would be at 480 volts.
277/480 voltages are used almost exclusively for commercial and industrial applications. that kind of voltage you might find in a factory or metal fabrication shop for large tools and motors.
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.
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.
Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.
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.
Current in 200kw at 480 volts = 200,000/480 = 416.667 amps

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.
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.
There are two types of water pumps, submersible and fixed position. Each pump is wired differently from one another. Use the discussion page to state what type of pump you are talking about.
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.
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.
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.
