Bonding & Grounding

More Information about Grounding and Bonding

For grounded systems, the National Electrical Code (NEC) requires you to perform all of the following: electrical system grounding, electrical equipment grounding, electrical equipment bonding, and bonding of electrically conductive materials.

FAQs

In grounding and bonding connections, do two metals need to be electrically connected and have the same electrical potential to achieve electrical continuity?

Yes, in grounding and bonding connections, two metals need to be electrically connected and have the same electrical potential to achieve electrical continuity and ensure safety.

What is a good equipment grounding conductor to prevent ground fault and static electricity incidents?

A good equipment grounding conductor is typically a copper wire, due to its excellent conductivity and corrosion resistance, ensuring reliable prevention of ground faults and static electricity incidents.

Grounding vs. Bonding

Bonding

Bonding is simply the act of joining two or more electrical conductors together. The bonding must be done to the areas of equipment that are not intended to carry any current during normal operation. Bonding itself does not protect anything. However, if one of those pieces of equipment is earthed, there can be no electrical energy build-up.

Grounding

Grounding is connecting the live part (meaning the part which carries current under normal condition) to the earth. This is normally done for the protection of power system equipment and to provide an effective return path from the machine to the power source.
