Neutral ground bonding- After Transformer

[mathan1987]

Hi

I am connecting a 208V panel at secondary side of a 480V/ 208V Y transformer. Is it enough to bond the neutral and ground at transformer or Do i need to bond the Neutral and ground in the 208V panel as well.

thanks

Only bond in one or the other, or else you will create a path for parallel neutral current.

And where you make the bond (SBJ) is where you terminate your GEC.
