I am wiring a 480 volt motor. I have a 277/480 volt panel
I am wiring a 480 volt motor. I have a 277/480 volt panel. On the motor there is a low voltage wiring and a high voltage wiring. Do I just use the high voltage wiring diagram or do I need to change some wires in the panel
How many wires are in a 277 volt circuit? - Quora
You’re probably talking about a 3-phase 277/480V wye (star) circuit, widely used in commercial and industrial establishments in North America. The voltage from each phase to neutral is 277V, and the voltage between any two phases is 277 * sqrt(3)[PDF]
10 and 12 Lead High-Wye Available Voltages
10 and 12 Lead High-Wye Available Voltages 10 lead generators are identical to 12 lead generators with the exception that T10, T11, and T12 are permanently bonded together as T10 or T0
Electrical Service Types and Voltages – Continental
Used in older manufacturing facilities with mostly three-phase motor loads and some 120 volt single-phase lighting and plug loads. Similar to the Three Phase Three Wire Delta discussed above but with a center-tap on one of the transformer winding to create neutral for 120 volt single-phase loads.
