RESETTING AND/OR REPLACEMENT



One device used to protect electrical components from burning out due to excessive current is a circuit breaker. Circuit breakers rapidly open and close the flow path for the electricity, in order to protect the circuit if current is excessive. A circuit breaker is used on components which are more likely to draw excessive current, such as a breaker often found in the light switch that protects the headlight circuit. Circuit breakers are found in the protected component, the fuse block. Circuit breakers pull out of the fuse panel just like a regular fuse. The breakers are self-resetting.
