480 to 208 transformer wiring.

If that transformer has percent taps, (the wiring diagram on the cover should show these) you can boost it some more by moving these to the highest voltage tap. ... I have done this with a 480/120/208 (delta/WYE) transformer backfeeding it with a 240 delta service and actually got 600 volts and had to back the taps down to get the 560 volts I ...The 480 Delta to 208 Wye transformer wiring diagram is used to connect a 480 volt Delta three-phase source to a 208 volt Wye three-phase load. This type of wiring is important in industrial applications, as it provides the necessary power reliability while using safety precautions.To get 277V out of a 480V 3-phase system, you should use a star connected 3-phase supply and connect only one of the phases and the neutral to the primary winding of the transformer. Doing so, you will get a 240 output in the secondary winding. In homes, you may use 240V or 208V in that case knowing how to wire 208V single phase will come in handy.THIS IS A STEP UP TRANSFORMER / SPECIALLY MADE TO TAKE A LOWER 208 VOLTAGE, 3 Phase-3 Wire & STEP UP TO 480 Volts, 3 Phase-4 Wire Manufacturer : Jefferson Electric Catalog Number : 423-9211-000 KVA : 45 Phase : 3 Primary Voltage / High Side : 208 Delta, 3 Wire Secondary Voltage / Low Side : 480Y/277, 4 Wire Max Temp Rise : 150 Deg C Lugs ...MT-DOE16-1P-480V-10KVA-120.240V-N3R Wiring Diagram WARNING: DO NOT SERVICE WHILE ENERGIZED!

We put in a 3 phase transformer (480V - 208/120). We only needed single phase on the secondary panel. I should have ordered a single phase transformer with a new 2 Pole breaker for the switch gear that feeds the transformer. I ordered the 3 Pole breaker for the transformer, a 3 phase transformer, and a single phase panel.

You can get away with reverse feeding a 480 to 208 transformer, but the 480 volt side is typically a delta winding and you would need to either make it a corner grounded system or provide ground detectors to indicate a ground fault on an ungrounded 480 volt system.Wiring diagrams, sometimes called “main” or “construc-tion” diagrams, show the actual connection points for the wires to the components and terminals of the controller. They show the relative location of the components. They can be used as a guide when wiring the controller.
