480 to 208 transformer wiring
M. micromind · #4 · Jan 26, 2018. 150 KVA @ 480 3Ø = 180 amps. You can feed it with a 200 but if it's loaded to the gills, it'll push the 200 a bit. 150 KVA @ 120/208 3Ø = 416 amps. This would obviously overload a 400 amp panel. If the 400 amp panel is loaded to the full 400 amps, you'll see roughly 172 amps at the 200 amp breaker.15 Apr 2009 ...

Ungrounded 480V distribution has been known for serious ground-overvoltage problems for close to 50 years. There is ample discussion at this site. One "reason" for not wanting Y-grounded service is that NEC 230-95 ground-fault protection is required, and that costs a bit more money. This is very poor, short-sighted thinking.Your 480v hot connects to H1. Your 480v white connects to H4. I'm not 100% on this part but from what I recall from school u need a jumper between H2 and H3. So they r in series. On the lv side 120v. Your 120v hot connects to X1. Your120v white connects to X4. Then jumper between x1-x3. And another jumper x4-x2.Transformer fusing tables for power line construction and maintenance - EatonThis pdf document provides guidelines and tables for selecting proper fuses for various types of transformers and applications.
