What role does a circuit breaker play when the appliance is shorted?


What is the role of a circuit breaker in the event of an electrical short circuit?

 

A short circuit is a circuit or a portion of a circuit that is shorted. For example the two ends of the load and the power supply are connected by wires; it is called a short circuit. The current provided by the power supply during a short circuit will be much larger than the current provided by the path. Generally, a short circuit is not allowed. If the short circuit is severe, the power supply or device will be damaged.

 

Short circuit with electrical appliances is also called partial short circuit. That is, a wire is connected to both ends of the electrical appliances (the ammeter is connected in parallel, and the closed switches are connected in parallel). This electrical appliance is short-circuited, and it is easy to burn other electrical appliances.

 

What equipment protects our home when electrical appliances are shorted? It is the miniature circuit breaker. When a short circuit occurs, the circuit breaker will detect an unstable current and trigger the short circuit protection function. As the home inspector, it will always protect the safety of household electricity and prevent accidents.
