Why Part of a Home Lost Power

What will cause lost electric power to part of our home? Possible Electrical Problems that can Cause a Home to Lose All or Part of the Electrical Power.

Lost Power to Part of a Home
Electrical Question: What will cause lost electric power to part of our home?
Example #1: We lost power to parts of our home. The ceiling light does not work, and the light over sink does not work, and a wall outlet does not work.

Example #2: All my breakers are on but I don’t have power in all the house.

Example #3: We have lost power to part of our home. The electrical power goes out in a large section of my house, leaving the living room, the refrigerator and microwave still with power.
