Circuit Breaker
- A device that can automatically stop an electric current, before it becomes dangerous. The circuit breakers are housed in a panel box, and is usually located in a service zone like kitchen (for residences) and electrical room per floor (for large buildings).
- This is a centralized control board which is found on each floor or major area of a building.
- A circuit breaker can be turned off for a particular floor, if the said floor needs an electrical repair or maintenance, for the safety of the electrician / repair men from electrocuting.
