11. That is some 33 amps at 220 volts on single phase . 12. A form 2S watt-hour meter used for single phase 120-240 volt, 3 wire systems. 13. The work may have been single phase , or added over several stages of modernisation. 14. I don't see how a single phase will keep it rotating under any load. 15. All versions can be used for single phase and, much more commonly, three phase applications. 16. Single phase AC-power lines as used for traction current have four conductors for two circuits.17. A 3-wire system with two phase conductors 180 degrees apart is still only single phase . 18. Additionally, such composites have yielded higher strengths than those observed for single phase solid-state components. 19. Self authorship is only a single phase of development within the lifelong process of self-evolution. 20. The site would be developed in a single phased and completion is expected in 2017.
