yes
A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors. (*A two-phase generator has two phase windings, displaced from each other by 90 degrees.)
Assuming this is a WYE connected system: (Most commercial/industrial services are) Your question answered it: 480 volts. The phase to phase voltage on this system is 480 volts and the phase to ground voltage is 277 volts.AnswerThe 'leads' you refer to are more-properly called 'lines', and the voltage between any pair is called a 'line voltage' (not a 'phase voltage', as stated in the original answer). The rated voltages of three-phase systems, regardless of whether they are three-wire (delta) systems or four-wire (star/wye) systems are always quoted in terms of their 'line voltages'. So, to answer your question, the line voltage ('voltage between leads' ) of your three-phase system is 480 V. If your system is a four-wire star/wye system, then the phase voltage voltage, or 'line-to-neutral' (not 'phase to ground') voltage is the line voltage divided by 1.732, i.e. 277 V.
Any two legs of a three phase system are classed as single phase. So yes a single phase motor will operate when connected. Be sure to use the proper motor protection devices to control the motor.
If you are referring to a.c. three-phase systems, then a three-wire system is associated with a delta-connected system, while a four-wire system is associated with a star, or wye, system. The conductors being three line conductors and a neutral conductor.
A balanced three phase system is where the currents into the loads placed on all three phases of the service are reasonably close to each other in amperage.Another opinionA 'balanced' three-phase system describes a three-phase load in which each phase current is identical in both magnitude and phase. If the phase currents are only 'reasonably close', then the load is not balanced.
Phase II identifies the requirements for the systems. It includes systems analysis, user requirements, necessary hardware and software, and a conceptional design for the system.

It helps in product life cycle
Phase IV is the implementation of the system. The new system is converted from the old system, and the new system is implemented and then refined. There must then be ongoing maintenance and reevaluation
3 phase system has more power than a single phase system
1- System Implementation is fourth of five phases in the systems development life cycle (SDLC). In the systems design phase we developed a physical model that include data design, user interface, input and output design, and system architecture , Now we are in the system implementation task which includes application development, testing, documentation, training, data conversion, system changeover, and post-implementation evaluation of the results. At the conclusion of the system implementation phase users will be working with the system on a day-to-day basis, and will focus on system operation, security, and support which is the final phase in the SDLC. 1- System Implementation is fourth of five phases in the systems development life cycle (SDLC).

a system development life cycle consists of analysis,design,construction,testing and implementation.When a system is to be designed it needs a proper analysis or you can say proper investigation which includes requirements,use and future scope of a system.An analysis is the starting phase for a system which will be designed.Even a successful and through systems planning analysis and design can be ruined if a poor system is constructed as this phase consist of coding & logics and if the coding and logic and coding are not correct the implementation will also effect.That is the reason a proper check should be made in construction phase that the analysed data is up to the mark.
Phase I is systems planning. The systems team must investigate the initial problem by determining what the problem is and developing a feasibility study for management to review.
Polyphase systems are used because they allow the efficient transmission of electric power, in terms of power transmitted per kilogram of wire. Polyphase systems with more than three phases are very uncommon.
No, that is false.

False.
