The question is can I just disregard the X0 terminal as I haven't a neutral on our 3 phase 208. And is the 3 phase 480 I will end up with going to be stable.
varmit · #2 · Jul 11, 2020. If there are any across the line motor starters of any sizable horsepower, a 30 kva transformer could be to small to handle the inrush demands. That being said, #8 fused at 50 amp would be minimum on the load (480) side.The line (208) side would need to be minimum #3 fused at 100 amp.Are you trying to figure transformer primary/ secondary? infinity Moderator. Staff member. Location New Jersey Occupation Journeyman Electrician Mar 13, 2018 #4 You could just do a ratio of the 480 volts to 208 volts. For volts 480/208 or 2.3 to 1. For amps 1 to 2.3. Ex. 480v and 10 amps = 208v and 23 amps. J. JFletcher Senior Member.Crossboss. IMHO the ideal transformer for this job is a 208V delta to 480/277V wye step up transformer. Probably 45 or 75 kVA. The current at 208V must be greater than the current at 480V, so you are correct, 100A at 208V is the equivalent of of about 43A at 480V. ….

Feb 9, 2023. #6. Junior_EE said: Because of supply chain issues, a client is looking to select a 480V chiller despite our building having only 208V. Obviously we need a step-up transformer to accommodate the load. Here is the info on the chiller @ 480V from the manufacturer: 359A MCA. 600A MOPD.We put in a 3 phase transformer (480V - 208/120). We only needed single phase on the secondary panel. I should have ordered a single phase transformer with a new 2 Pole breaker for the switch gear that feeds the transformer. I ordered the 3 Pole breaker for the transformer, a 3 phase transformer, and a single phase panel.3-4 Wire 3-Phase; 3-4 Wire Single Phase; 4-5 Wire 3-Phase; Pin & Sleeve; Extreme All Weather Cords; Ground Fault Circuit Interrupters.
