What is a Breaker?

A breaker, also known as a circuit breaker, is a crucial element in an electrical system. Its primary purpose is to safeguard the electrical wiring and appliances from potential dangers caused by overloading and short circuits. By monitoring the flow of electricity passing through the wires, the breaker acts as a safety device. When there is an excessive amount of electrical current, the breaker automatically shuts off the flow of electricity to prevent any damage or hazards.

The breaker’s functionality is based on its ability to handle a specific load of electrical current, which is typically measured in amps. If the current surpasses the safe threshold, the breaker trips and disrupts the flow of electricity.

To restore the functionality of the breaker, you must locate the circuit breaker panel in your home and return the switch to the “on” position. It is crucial to have an understanding of the electrical load of your appliances and devices and distribute them across different breakers to avoid overloading any single circuit.

The origins of the breaker can be traced back to the early 19th century when electrical systems were first being developed. During that time, fuses were commonly used as protective devices. However, fuses had a significant drawback as they required replacement each time they blew. In the late 19th century, circuit breakers were introduced as a safer and more convenient alternative for electrical protection. Since then, circuit breakers have become a standard and indispensable component in electrical systems, ensuring the secure and efficient distribution of electricity.
