jsciarlo said: The tranformer that is there is a 460 primary to 120/240 secondary. Oh, so the main service is 480. Doesn't sound like it would be a problem, although its more common to stick with equipment that works with the available voltage. A lot of equipment will work with either 208 or 240 volts.I have a transformer with the following nameplate 750kVA, 480V-208/120V, 3P, Z=5% I got a rating of 41.6kAIC and rounded to the nearest standard I get 42kAIC. But from the Engineering drawing, the MDP after the transformer is rated with the following data 1600A, 208/120,3P,4W and a 14kAIC. How did they get a kAIC of 14kAIC.The input side was 480 volts (V), three-phase, and the output side was 120/208V. They wanted to know if the output side of 120/208V transformer could be used as an input side, and if so, how was the electrician to bond and ground the transformer? ... cannot be derived from a reverse-fed transformer because standard transformers are not usually ...

I can understand this scenario if you have non-linear loads fed from the transformer. One other interesting thing I read was "The neutral conductor of a 3-wire circuit from a 4-wire 3-phase 120/208V or 277V/480V wye-connected system is considered a current-carrying conductor".Generally, you would run 4 wires from the transformer to the panelboard.For this exercise, let's assume we are installing a 45 kVA and a 112.5 kVA 480V delta primary to a 208Y/120V 3-phase wye secondary. Each transformer supplies a lighting and appliance branch circuit panelboard with continuous nonlinear loads, typically found in today's office buildings.
