The Electricity powers our world, but it must be handled with great care. The Safety Practices ensures electrical system remain safe and efficient: Earthing, Bonding and Grounding. Though these terms are often mixed up, they serve different purpose.

| Difference between earthing Bonding and Grounding |
Earthing
Earthing means connecting the electrical installation to the earth (ground), usually through a metal rod or plate buried in the soil.
Purpose
To provide a Safe path for fault current (e.g. When a live wire touches a metal casing), ensuring the excess electricity flows into the earth, not into human body.
Example :
If a washing machine has a fault and its metal body becomes live, earthing ensures the electricity flows to the ground instead of shocking anyone who touches it.
Bonding
Definition
Bonding involves connecting all exposed metal parts (like water pipes, metal frames etc) together with a conductor wire to keep them at he same electrical potential.
Purpose
To prevent dangerous voltage difference between metallic objects .This reduce the risk of Electrical shock if a fault occurs.
Example:
if your bathroom has a metal tap and metal shower fitting, bonding ensures they are at the same voltage level. That way ,touching both at once wont give a shock.
Grounding
Grounding usually refers to connecting parts of an electrical system to the earth, like the neutral point of transformer or generator.
Purpose
To stabilize voltage during normal operation and help in fault detection , its essential in power distribution system to avoid overvoltage.
Quick Recap
Term Purpose Example Usage
Earthing Direct connection to earth for Safety Fault current flows to earth
Bonding Connect Metal parts to prevent shock Joining water pipe and heater body.
Grounding Stabilize voltage and fault path Connecting transformer neutral.
