I understand the importance of not having an equipment ground in a remote distribution (sub-panel in most cases) sharing the same bar as the neutral conductor. However, I ran across a unique situation today with a sub panel bonded to the primary panel. The sub panel had one A/C circuit and two additional branch circuits. The Equipment ground of the A/C circuit was connected to the neutral bar. The two other branch circuits looks like were moved from the primary panel to the sub panel by extending the hot conductor, but the neutral conductors were not moved (in essence using the primary panel as a junction box (a no no).
- In the case of the A/C, isn’t the bare conductor actually the neutral conductor and OK to be connected to the neutral bar?
- What happens to the two additional branch circuits? The cable is physically not long enough to reach. Should a j-box be installed above the panel and then re-wired?
- Are Type HOM breakers rated to fit in an Siemens panel?
