Forklift pockets or lifting eyes included to transport by trailer Sep 10, 2008 · Sep 10, 2008. #4. Make sure you can live with a an unground delta at 480V. Also, remember that the 480-208Y/120V has the low side lagging by 30 deg. if you go 208Y/120V-480V, you are going LV wye/HV delta, so make sure if you have a secondary feed to the equipment that the phase angles match-up. M. Mar 9, 2009. #4. As you step up the voltage you are stepping down the current. (total power stays the same if you ignore all the transformer and wire losses.) So your 600A service is only going to give you about 260 amps at 480. (208/480) * 600 = 260. Steve.#1 Hello everyone, I'm having trouble trying to size a 3-phase transformer.
