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.
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
Yes, a 3 phase 95 millimeter for each phase 150 meters long cable is enough for a 285 KVA genset.
A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.
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.
see cable table chart
yes we can use as a single phase circuit because at practise directly the 3-phase circuit is made by combining the three single phase circuits
single phase have 2 wire treephase have 3, and 4 wires
3 phase cable is transposed to minimize the effect of leakage/capacitance current.
3 pole circuit breakers are used for 3 phase lines
If by 'cable wire' you mean Coax cable for the TV, or Internet, then the answer is no. The power/voltages in the cable are way to low to produce a spark which is usually what triggers flame. If by 'cable wire' you mean a cable carrying an electrical service such as 120V or 240V, then, if the cable is damaged by an accidental or deliberate cut which causes a short circuit from a hot phase wire or wires to other wires in the cable - such as to other hot phase wires in a 3-phase circuit, a neutral or a ground wire - then the resulting heavy current could result in the cable becoming very hot and could cause it to catch on fire unless there was some overcurrent protection device to prevent that from happening. That is why fuses and/or circuit breakers should always be included in any electrical service wiring to cut off the supply of current before a fire can be caused by such damage.
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.
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.

your not completing the circuit your only using one phase for a three phase motor
Yes, a 3 phase 95 millimeter for each phase 150 meters long cable is enough for a 285 KVA genset.
We can convert a 3 phase ac motor into generator by changing phase sequence of the ac input cable of that motor
About one million circular mill. You need to up the voltage.
