This question already has an answer here:

I have an old house that was remodeled with a bathroom addition added years ago. I have two breaker panels: the outside service entrance panel (A) and another panel in the garage (B). I found bonds from neutral to ground at the service entrance panel (A) and in the garage panel (B).

The service entrance panel (A) was added for the remodel; it has a 125 amp breaker that feeds the garage panel (B) (3 wires: 2 hot and 1 neutral but no ground). It also feeds the bathroom addition. The neutral and ground are bonded in both panels.

What panel should have the neutral and ground bond?

  • I went into some pretty good detail of how sub panels should be installed in this answer - in short, you bond only in the primary panel, ground and neutral need to be isolated in secondary panels. – Tim Post Jul 15 '15 at 5:47
