Two of the three phases makes single phase, it isn't to ground or nuetral, just use two of the leads and you have 460 single phase. One leg to ground would be 277 more commonly used for lighting in a building.
The chart below displays information for motor wire size, breaker size, thermal overload ratings, and other data for three-phase AC motor circuit protection. Full-Load Current and Circuit Protection Data for Three-Phase AC Motors
Im ready to change the wiring from 460 To 230 3 phase, and I cannot find a wiring diagram on line Jraef, the motor tag states 208-230/440v 3 phase. No diagram anywhere on the motor It has 9 wires. So i Ohmed the windings to determine I had DELTA.
The Motor Wire Size Calculator will calculate the proper wire size for a given motor HP and voltage. This applies to three-phase AC motors. This calculator will also give you motor amps and recommended breaker size, starter size, heater size and conduit size. Motor Wire Size Calculator
Recommended dimensions of copper wire and transformers for tree phase 230 & 460V electrical motors . Sponsored Links . All wiring and electrical connections should comply with the National Electrical Code (NEC) and with local codes and practices. electrical motor wire three phase 230 460
A three-phase motor is more efficient than a single-phase motor because of the peculiarities of alternating current (AC). Wire a three-phase motor in either a wye configuration or a delta configuration, in high or low voltage, using a nine-lead set-up.
