I have a stepdown transformer 480V-120V. Usually for single phase, 120 Volts is line to neutral, is there any code violation per NEC 250.26 if the connection is 120 Volts line to line, both conductors are ungrounded?
Hey Jesus thanks for your question. A Neutral Conductor only exists if it is connected to a Neutral Point as those terms are defined in Article 100. If the transformer secondary (120 volt) only has two termination points there is no neutral point therefore no neutral conductor.
