Circuit breaker is an electrical switch that is designed to protect an electrical circuit from damage cause by several factors such as
Electricity overload- Overload is an excess amperage flowing over a circuit.
Short Circuit- an unexpected electrical flow,that travels from sources that are electrically conductive.
Reason for electricity overload- Loose or corroded wires and connections electricity coming from a lighting bolt
Reason for short circuit- Wire being stripped and touch by a tree limb Two wires with different voltage touching together
Circuit breaker components
