Oct 19, 2021 · I have 208/120v coming in on a 100amp disconnect on a bus duct and need to temp in a 480v AHU package unit with mop at 60 Amp. Is this doable with a step up transformer and what size should it be. Can I get the 60 amps from the 100 amp breaker or would I need a larger breaker assuming this calculation is correct 208 x 480= .433 x 100= 43.3 . 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 receptacles. The output of the transformer would …Generally, if the transformer is mentioned by 11kV/415V means, it is called step-down transformer, the input will be given as 11kV and the output will be connected to 415V. At the same time, the transformer is mentioned by 22kV/220kV means, it is called a step-up transformer. The input will be 22kV and the output will be 220kV.Terry Lundgren is preparing to step aside as the CEO of Macy's.

THIS IS A STEP UP TRANSFORMER / SPECIALLY MADE TO TAKE A LOWER 208 VOLTAGE, 3 Phase-3 Wire & STEP UP TO 480 Volts, 3 Phase-4 Wire Manufacturer : Jefferson Electric Catalog Number : 423-9211-000 KVA : 45 Phase : 3 Primary Voltage / High Side : 208 Delta, 3 Wire Secondary Voltage / Low Side : 480Y/277, 4 Wire Max Temp Rise : 150 Deg C Lugs ...JRaef · #7 · Mar 15, 2022. On the 208V side, you do NOT connect the X0 to anything, let it float. On the 480V side, IF it is a 480/277V Wye winding, you WOULD bond the X0, but likely not run it to the AHU unless it says it needs it (and that would be unlikely). If the 480V side is Delta, there is no X0, but you would need to either corner ... ….
