I have a 3 Phase 480V motor fed from a 20A cb powering an exhaust fan. There is a 120V motor operated louver that needs powered when the fan is running.
We are thinking of using a 50VA 480V:120V transformer connected to two lines of the motor circuit to power the louver motor operator.
Do I need an ocpd for the transformer? Are there any other considerations with this solution?
