Neutral Vs Ground Bus Bar

The neutral is isolated from the metal enclosure.

Neutral vs ground bus bar.

Personally i prefer to put them on separate buss bars usually there is one on each side of the box also while not specified in the codes i will never put both the white and ground wires under the same screw. Earth or ground wire is assumed to be at zero potential while the potential of neutral depends upon unbalance between the wires. In this case the ground bus is electrically connected to the neutral bus in main service panels only. Neutral is provided by the power company to make the path of electricity closed.

In any distribution panel there are individual bars for each termination. Ground is therefore universal reference which is always taken to be zero potential. Ground bus bar some service panels have a separate bus bar for ground wire connections instead of a neutral ground bus. Under certain conditions a conductor used to connect to a system neutral is also used for grounding earthing of equipment and structures.

The ground buss is in direct contact with the metal enclosure. The difference between a ground wire and neutral wire is often misunderstood. In an entrance panel both bus bars are grounded to the box. Thank you for your question regarding the separation of the ground bar from the neutral bar in an electrical sub panel it is our pleasure to help.

The problem primarily comes from the inappropriately named neutral wire. In subpanels the ground bus and neutral bus are not connected to each other. A double tapped neutral is when more than one neutral wire is fed into a single screw terminal on the neutral bus bar in the main electric panel. As the neutral point of an electrical supply system is often connected to earth ground ground and neutral are closely related.
