What is the importance of circuit breakers?

A circuit breaker automatically disrupts the flow of a current if there’s a short circuit or overload. In doing so, it can prevent damage to an electrical circuit and possibly appliances, electronics, and your home.

How does a circuit breaker protect you?

A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by overcurrent/overload or short circuit. Its basic function is to interrupt current flow after protective relays detect a fault.

What are the importance of circuit breakers fuses and other safety devices at home?

Circuit breakers and fuses interrupt excessive currents to prevent thermal hazards. The three-wire system guards against thermal and shock hazards, utilizing live/hot, neutral, and earth/ground wires, and grounding the neutral wire and case of the appliance.

Can a bad circuit breaker cause a fire?

A circuit breaker protects an electrical circuit from damage by automatically shutting off power to the circuit. Breakers trip because of overloaded circuits, power surges or spikes, a short circuit, and ground fault. If the circuit breaker fails, it can damage appliances or equipment on the circuit or lead to a fire.

Does a circuit breaker protect the wire or the device?

The fuse or breaker at the main service panel or sub-panel protects the circuit wire against dangerous overloads. The equipment fuse or breaker protects the individual piece of electrical equipment and adds safety to the system.

Why is it important to use electrical safety devices at home?

The voltage of the available electrical current in a household has enough power to cause severe third-degree burns and even cause death by electrocution, which is why it’s essential to be aware and take necessary precautions to ensure complete electrical safety, especially if you have children at home.
