What is a circuit breaker?


Circuit Breaker

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

Switch lever
Contact mechanism
Metal contacts
Bimetallic strips
Calibration screws
Arch divider
