Theoretically that can be done with Transformers, but the power available would still be limited by the circuit breaker on the original 120 v supply.
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
residential wiring are called single phase because the 2 phases coming in are one is neutral and the other is line.the neutral has a potential zero with ground and it is to provide a closed path for the current to flow through..the line is having a potential of 230V with the ground and a line together with a neutral is called a phase
A connection can be taken between phase lines, or between one phase and neutral. Both methods give a single-phase supply. Between phases the voltage is sqrt(3) times more than between one phase and neutral. In each case the load gives an unbalanced current on the 3-phase system but the idea is to average out the unbalances over a group of single-phase loads.
Both are possible. Single phase requires a neutral (or two phases, such as "Single-phase 240 V) to return the un-used voltage on the "down side" of the generating cycle. Three phases equal "each other out" on the up and down side. One phase generating positively while the other two are at various points of positive and negative on the sine wave to balance each other out.
I depends on what you are connecting to it but you only need 1 of the phases providing you can get to a neutral
you can't do this. to get single phase from 3 phase you must disconnect 2 of the phases and use one of them as a neutral...b.
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
I'm not sure what your question means as a single phase supply is normally one of the phases and the return/neutral, not all 3 phases converted to one, plus return.

On a Delta 3-phase you connect the single phase loads between pairs of the 3-phases. Warning both sides of these loads will be hot! You may want to use 3 isolation transformers so that the real loads have a neutral line.On Y 3-phase you connect the single phase loads between one of the 3-phases and neutral.In each case to balance the loads, try to put similar loads on each phase (or pair of phases).

As many single phase loads as is needed by the installation. The key to loading the three phase wye system is keeping the current equal in all three phases. As the neutral only carries the unbalanced current it is prudent to keep the current as low as possible by equalizing the loads on the phases.
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).

By having a transformer with 3 phase input and single phase out put
Mark the phases red (phase) black (phase) and blue (phase) along with a white (neutral) and a ground (wire size depends on the main breaker amperage) the phases attach to the main breaker unless it is a breakerless panel attach the phases to the lugs on the bus bars top or bottom then connect the neutral to the neutral bus and the ground to the panel
How much current equipments are drawing from three phases (combined or individual) is called three phase load and how much supply we are getting from source is called three phase supply. Ex. In INDIA single phase supply is 220 volt ac with neutral. So in three phase supply all RYB phases should be 220 volts ac with neutral individually. If we calculate with phase to phase than it shoulb be 415 volts ac.
