Thus, the term “grounding.” Grounding protects your family, and any sensitive electronics in your home.

What does it mean when an appliance is grounded?

Grounding gives electricity the most effective way to return to the ground via your electrical panel. A grounding wire gives an appliance or electrical device a safe way to discharge excess electricity. When an electrical malfunction occurs, this power will be stored in internal wiring and external metal housing.

How do I check for bad appliances?

1. Visual Inspection.
2. Earth Continuity Test.
3. Insulation Resistance Test.
4. Leakage Test.
5. Further tests have to be performed on leads, RCDs etc.

What should the temperature setting of the freezer section of a refrigerator be?

0° F

Is 10 degrees too hot for a fridge?
