Xfmr voltage

What does 380 v look like on a line diagram ...delta is a delta Wye is a Y.

The secondary is a wye, just like 480Y/277 or 208Y/120...just a different voltage. I believe that 380Y/220 is a common voltage in Europe.

So the configuration. Is the same. Delta to Wye.

What size sec would you prefer @ 500 amps. Single. Parallel,x2x3x4?

 

[electricalist]

The drawings already define the raceway size ,amount as well as the feeders. Its only gonna have 2 conduits feeding it.
My question is more about If you can run more parallel feeders is it done for pricing , because it's less labor intensive or better electrically?

I believe that 380Y/220 is a common voltage in Europe.

Nominally 400/230.
