If you have a 208Y/120 volt 3 phase system, you can use any one of the three phases (hot or ungrounded conductor) with the neutral for 120 volt load or you can use any two phases of the three phase for a single phase 208 volt load.

If you have a 120/240 volt 3 phase system, you can use any two phases of the three phase for a single phase 240 volt load or you can use either the A phase or C phase with the neutral for a 120 volt load. You can not use the B phase with a neutral (you would have 208 Volts!).

Can you use 3 phase circuit as 3 separate single phase circuit?

Yes, a 3-phase circuit can be used as three separate single-phase circuits by connecting each load to one of the phase conductors. This allows you to operate three independent single-phase loads using the same 3-phase power source. However, caution should be taken to ensure that the loads are balanced among the phases to avoid overloading any of the phases.


When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?

In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).


Cell division is accomplished by what?

there are 6 stages of cell division. Phase 1- interphase Phase 2- prophase Phase 3 - metaphase Phase 4-anaphase Phase 5-telophase Phase 6- cytokenesis


What are the 4 phases of micro organism growth?

1. lag phase- cell does not increase in mass2. exponential phase-cell grows at maximum concentration3. stationary phase- straight line phase.balance between cell death and cell division.4. decline or death phase- cell death increase and cell division decrease.


What is the relationship between phase and line voltage in a 3 phase generator?

The Voltage produced by the generator will be like 3 sets of your home's voltage (assuming we're looking at an outlet and not the 220V at the brkr box).Each phase (sinusoidal wave) will be separated by 120 degrees, so when the 1st phase starts the 2nd phase will start 1/20th of a second later. The 3rd phase then starts 1/40th of a second later, and the 1st phase starts again 1/60th of a second later which is the beginning of the second set of sin waves. This of course is based on the N. American Frequency of 60 hertz which is 60 cycles (waves) per second.AnswerFor a three-phase, three-wire, system the line voltages will be identical to the phase voltages.For a three-phase, four-wire, system the line voltages will be 1.732 times the value of the phase voltages.

If 3 phase 240 is used to power a piece of equipment that should be powered by 1 phase 240 will it damage the equipment?

As only one phase of a 3-phase supply can ever be properly connected to a piece of 1-phase equipment, such as a motor or whatever, no damage will result if that connection is done correctly.As most household 1-phase ac power is derived from power generated and distributed as 3-phase power, this question may just be an exam question designed to catch out students who don't really know what they are talking about...For more information please see the answer to the Related Question shown below.
