Electrical installation grounding – what it protects and why it is necessary

What grounding does

Grounding creates a safe path for fault current and helps protection devices function correctly.

What should be checked

• The continuity of the protective conductor.
• The connections at the grounding busbar.
• The metal casings of appliances.
• The condition of the grounding system.

Important

An installation may appear to be operating normally but can be dangerous if the grounding is inadequate.
