5 Questions
Question 1 of 5
What is the primary function of earthing in an electrical system?
Earthing provides a low-resistance path to the earth for fault currents, preventing electric shock.
Question 2 of 5
What is the main purpose of bonding in an electrical system?
Bonding equalizes the electrical potential of all exposed metal parts, reducing shock hazards.
Question 3 of 5
What is the ideal earth resistance value for an earth electrode?
A low earth resistance ensures that fault currents can dissipate quickly and safely into the earth.
Question 4 of 5
Which test is used to check that all conductors are properly connected to the earth?
The Earth Continuity Test specifically checks the integrity of the earth connections throughout the system.
Question 5 of 5
What is the acceptable bonding resistance between metallic parts?
Bonding resistance should be as low as possible to ensure effective equipotential bonding.
