480 to 208 transformer wiring.

The input to the power supply is 480V 3 phase (no neutral, just 3 phases and 1 ground). I want to use this in our facility but we only have 208 3 phase. Short of having a major change to our facility power, I thought of this. I want to get a small step-up transformer (about 9KVA) and wire it to plug in to one of our 208 3 phase 30 Amp …For example, a transformer that’s marked as 480V primary, 208V secondary can’t be wired with a 208V primary and 480V secondary. According to UL 1561, only transformers marked in this manner can be installed this way. The 2014 NEC also revised the allowance for having a transformer disconnect remote from the equipment.The utility provides the site with a 480V single phase service. The Owner has an existing 480V transformer that gets the voltage down to 120V. This xfmr is being relocated, specs on it are: 15kVA, 60Hz, single phase, Primary Volts 432/456/480, Secondary Volts 120/240.

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. Figure 1 is a typical wiring diagram for a three-phase mag-The advantages of using a buck-boost transformer over an equivalent standard isolation transformer are: Advantages 1. Used in a variety of applications 2. Inexpensive and stocked voltage correction 3. Smaller and lighter than an isolation transformer Disadvantages 1. No circuit isolation 2. Cannot create a neutral 3.
