- Besides human safety risks, sensitive computers and electronics devices fail to operate properly and/or sustain damage at lower voltages which usually cannot be felt by humans, resulting in loss of productivity and expensive troubleshooting & repairs.
- Current also passes through the least path. In case of fault current, short circuit there is two options available for its dissipation into the earth:
Current may take the path of earthing
Current may take the path of human body of the affected person
- This depends on the least resistance of path between the two. Hence the resistance of the earthing should be always be lesser than the resistance of the human body.
- Earthing is absolutely necessary to protect human life and equipment from electrical hazards in this electronic age.
