Wiring 3 Phase Transformer Connection Diagram Three phase transformer connections (wiring diagrams. A 45 kva wye 480 277 v transformer primary would require a conductor ampacity of 54.19 amperes at 125 percent totaling 67.73 amperes. (45,000 830.4 = 54.19 x 1.25 = 67.73) our conductor size would be based on this number. note 1 to table 450.3 (b) allows us to round up to the next standard size of 70 amperes for our overcurrent device. Here is a step by step guide to help you wire a 3 phase transformer correctly: calculate the correct transformer size for your application based on the load requirements. this will determine the voltage and current ratings of the transformer that you need. locate the primary and secondary terminals on the transformer. • the wiring diagram in figure 3a can be made implemented using a bank (group) of three single phase (1Φ) transformers. • y y transformers are used in industrial applications and are preferred over ∆ ∆ transformers when it is critical to have a neutral connection in the secondary circuit.
