If it is powering a single 3 phase device and is protected by a single throw 3 pole breaker or disconnect, yes. If all three hots share one neutral, and supply different devices or circuits, breakers should be able to trip independently but would still have to disconnect all three phases together.
What else can I help you with?
Can one use 1 circuit of a 3 wire plus ground 2 circuit cable as a GFI circuit with the other as a lighting circuit?
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
Would a 3 phase 95 millimeter for each phase 150 meters long cable be enough for a 285 kva genset?
Yes, a 3 phase 95 millimeter for each phase 150 meters long cable is enough for a 285 KVA genset.
What AWG cable for 200' x 208 volt three phase 250 amp circuit?
A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.
What is the current carrying capacity of 15 meters of 25mm2 3 phase cable?
see cable table chart
How you convert the value of single phase power to value of 3 phase power?
Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.
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.
Why the 3 phase of high voltage conductor or cable transposed?
3 phase cable is transposed to minimize the effect of leakage/capacitance current.
What is the difference between single phase circuit and tree phase circuit?
A single-phase circuit has one live conductor and one neutral conductor, typically used for residential applications. A three-phase circuit has three live conductors and one neutral conductor, used for higher power industrial applications due to its ability to provide a more balanced power distribution.
3 pole circuit breakers?
3 pole circuit breakers are used for 3 phase lines
How do you wire 3 phase circuit using 4 core cable and earth in 3 way switch?
There are many ways to wire 3 phase circuits, depending on the application. AN answer here will necessarily be a simplistic and general one. From a safety aspect, anyone seeking information of this kind is not qualified to work on 3 phase electrical systems and to attempt it is risking injury or death. It's best to leave mains wiring to qualified professionals.
Can one use 1 circuit of a 3 wire plus ground 2 circuit cable as a GFI circuit with the other as a lighting circuit?
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
What is the rating circuit of the 3 phase appliance protector?
16A
You found a 220volt coil on a 3 phase motor contactor and the one side of the coil is feed from B phase and the other side is also feed from B phase it would not pull in the contactor?
your not completing the circuit your only using one phase for a three phase motor
Would a 3 phase 95 millimeter for each phase 150 meters long cable be enough for a 285 kva genset?
Yes, a 3 phase 95 millimeter for each phase 150 meters long cable is enough for a 285 KVA genset.
How do you turn a 3 phase motor in to a generator?
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
How many wires are in a 3 phase circuit?
A ground, or earth, conductor is never included in the conductor count. So, a three-phase, three-wire, system has three line conductors, whereas a three-phase, four-wire system, has three line conductors and a neutral conductor.
How can you earthed a 3 phase electric circuit?
To earth a 3-phase electric circuit, connect the earth wire from each phase to a common earth point, usually a grounding rod or plate buried in the ground. This helps to protect against electrical faults and ensures the safety of the circuit by providing a path for excess current to flow safely into the ground. It is important to follow local electrical codes and regulations when earthing a 3-phase circuit.
