Show Solution
Solution and Explanation
To conduct an earth fault test:
De-energize the equipment.
Attach an earth tester or insulation resistance tester between the equipment's chassis and ground.
Apply a test voltage (commonly 500V DC).
Record the resistance. A value exceeding 1 M Omega is required to confirm adequate insulation.
This procedure identifies potential leakage paths and mitigates the risk of electrical shock.
