Subject - the Same Difference?

The behavior (variables-dynamics, properties, etc.) of a circuit that has the ground and neutral combined in a seperate 30 amp breaker box that is connected to the main breaker panel with 3 inch metal conduit is absolutely no different than if that 30 amp circuit were connected directly to the main breaker panel in the same manner. Right?

| Correct but, this is not up to code. After the main disconnecting means the neutral and the ground should be kept seperate.

| Thanks, Scott. This is what I thought. Why does code dictate this? I appreciate your patience and thanks again.

| Because the connecting them in parallel causes objectional current to flow through the grounding system. If the neutral becomes opened then all the current that would normally flow through the neutral will now be going through the ground system which may not be capable of handling the current.
