Q: What is "grounding"?

Many people over-simplify, or even confuse the term Grounding with what should essentially be separated into three categories: Grounding, Earth Grounding, and Bonding...

Here’s a quick explanation...

Electrical Grounding is connecting to a common point, which is then connected back to the electrical source.  It is not necessarily connected to Earth (such as an aircraft’s electrical system). Earth Grounding on the other hand, is a term used to describe the connection of equipment and facilities grounds to actual "Mother Earth". And Bonding is the joining of metallic parts into a conductive path to carry anticipated current.  These practices, or combination of them, form the basic term known as Grounding.
