You need to look at wiring diagrams for 240/120 3-phase 4-wire connections. This system often goes by several slang name, a popular ones are 'wild-leg' and 'high-leg'.

Here is a picture gallery about 480v 3 phase wiring diagram complete with the description of the image, please find the image you need. If a How much 3-phase 240V?, How much single phase 240V, how much single phase 120V? But I noticed that no one seems to make a standard single phase under 1 kva, 240 x 480, 120/240 transformer in open style. The secondary winding can be “split” or “tapped”, to produce multiple voltages, such as, /V. As an aside, this transformer, being an enclosed potted type is not really typical of what would be used in a machine tool cabinet. Note how a center-tap terminal is used on the secondary of one transformer to ground the entire system. FORMULAS USED IN CALCULATOR: 1-Phase KVA = Volts x Amps / 1000 1-Phase Amps = KVA / Volts x 1000 3-Phase KVA = Volts x Amps x 1.732 / 1000 3-Phase Amps = KVA / Volts / 1.732 x 1000 Energy Efficient Transformers Three-Phase Transformers Three-Phase Transformers Refer to Tables 2–9 for three-phase transformer information. Table 11 Ratings for 120/240 V, 3-Wire, Single-Phase Dwelling Services101 Table 12 AWG and Metric Wire Data 102 Table 13 Electrical Formulas for Amperes, Horsepower, Kilowatts and KVA 103 Table 14 Ratings for 3-Phase, Single-Speed, Full-Voltage Magnetic Controllers for Nonplugglng and Nonjogging Duty 103 Table 15 Ratings for 3-Phase, Single-Speed, If you are using this unit as an isolation transformer with a primary of 120 or 240 or 480 volts and the secondary of 12/24, 16/32, or 24/48 (depending on the model) use the wiring diagram located on the inside of the cover to the wiring compartment. Before we go off into the weeds: what loading will you require? The neutral wire serves as common return to all the three phases acting outward from N 1. In a delta connected ( Dd ) group of transformers, the line voltage, V L is equal to the supply voltage, V L = V S.But the current in each phase winding is given as: 1/√ 3 × I L of the line current, where I L is the line current. The banking of these units results in a 240/120V, 3-phase, 4-wire secondary. The neutral points in both alternator and the load are joined together.
