480 to 208 transformer wiring
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-www.eaton.com. The secondary panelboard provided is 240/120V single phase. The designer has brought from the transformer secondary two legs two phase wires and one neutral wire and one equipment grounding conductor to the secondary single phase panelboard. The third leg/phase terminal of the transformer is left open nothing connected.

You can alternatively use kVA to Amps calculator for Conversions. 45 kVA transformer amps can be calculate using kVA to Amps conversion Formulas: List of Contents 45 kVA Single Phase Transformer Amps when V = 1.1 kV Amps = 45 * 1000 / 1100 = 40.9 Amps In case of Three-phase 45 kVA Transformer Amps = 45 * 1000 / (1100 * 1.73 ...Need some help.....I have a 3 phase 480V Delta Primary to 208V WYE Secondary dry transformer.....however it was hooked up in reverse.....whereas the Incoming Power is 208V and the Outgoing is 480V.....It feeds a 3 phase 4 wire 480 Volt Panelboard.....they installed a neutral wire from the XO terminal, thru a lug on the frame (stripped the insulation in the lug) and terminated it in the 600V ...
3-phase power systems: Y (Wye) and Delta. With a 3-phase supply you have two ways of connecting a traditional 2-wire load, such as a light bulb or a server. In a Y system you can connect it between any phase (X, Y or Z) and neutral (N). In both Y and Delta systems you can also connect it between any two phases (X-Y, Y-Z or Z-X).This is typically what you'll see in homes and small businesses. 120 volts and 240 volts for a single-phase, and 120, 208, and 240 for three-phase. Depending on how a transformer is wound at the service, you'll have 208/120 or 240/120, and in the case of a 3phase 4wire Delta application, you'll have 208/240/120 all in the same service.This is typically what you'll see in homes and small businesses. 120 volts and 240 volts for a single-phase, and 120, 208, and 240 for three-phase.

IS RATED FOR 3-PHASE 40 AMPS.I AM USING A 45KVA 3-PHASE TRANSFORMER 480-240V AND REVERSE THE CONNECTION.WHAT SIZE BREAKERS WOULD I NEED ON THE LINE AND LOAD SIDE.THANKS
The capacity of the 200 amp, 277/480 volt, 3-phase service is 166.3 kVA (200 amps x 480 volts x 1.732). This equates to 461.5 amps at 120/208 volt, 3-phase. If you want to convert the entire 200 amp 277/480 volt, 3-phase service to 120/208 volt, 3-phase, you would need a minimum of a 225 kVA transformer.What matters is only the total KVA of the loads. If your mission is to match a transformer size to the rating of a 200 amp panel, you get there by multiplying 200 amps times 208 volts times 1.732. That result is 72 KVA. Even if you allow for the short time overloading of a 45 kva transformer to a level of 125%, it would still only give you 56 KVA.So no, it seems the path of least resistance (or cheapness) is to change back the wiring I altered and use a transformer to step up from 208 3p to 480 3p somewhere in the 15 to 30kva range. The machine calls for 53 full load amps at 220 so 15kva is the smallest I can go with. ….

Motors loads are commonly connected to phases A, B, and C, while single-phase loads are connected to either phase A or C and to neutral. Phase B, the "high" leg, is not ...Section 250.20 (A) provides the requirements for grounding systems of less than 50V. The Code requires alternating current (AC) systems of less than 50V to be grounded under any of the following conditions: Where supplied by transformers if the supply system exceeds 150V to ground. Where supplied by transformers if the supply system is ungrounded.
