xformer question

[Ed Carr]

We are installing a 3 phase 480 volt service. I have a 50kva transformer
fed from a 100 amp 2 pole breaker in the 480 volt panel. My secondary
taps are 120/240 volt. The label on the cover of the transformeer reads
120 volt x1-x3 and x2-x4 and 240 volt x2-x3. My plan is to feed a panel for
offices. Where do I get my neutrsal from? The transformer is a Siemens.
In short I have H1,H2,X1,X2,X3 and X4.

Thanks, Ed

Look closer. Your 240v comes from X1 and X4, and your neutral comes from the junction of X2-X3.

Be sure to treat that neutral as you would any other as far as bonding and electrodes are concerned.
