A circuit breaker is an essential component of any electrical system. It prevents circuits from becoming overloaded and shorting out, potentially causing damage to electrical equipment and even starting fires. To understand how a circuit breaker works, it helps to look at a diagram.
A typical circuit breaker is composed of several components. At the heart of the device is a switch that can be used to turn electricity on or off. This switch is connected to two lugs, one on each side of the device, which are used to connect the circuit breaker to the power source. On the other side of the switch are two contacts, the “common” and the “trip”. The common contact is always connected to the power source while the trip contact is only connected when the switch is closed.
When electricity is flowing through the circuit, the current is constantly monitored by the circuit breaker. If the current becomes too high, the breaker will trip, disconnecting the power source from the circuit and preventing overloads and shorts. The breaker also has an indicator light which shows when the breaker has tripped.
Understanding how a circuit breaker works is important for anyone working with electrical systems. Knowing how to properly install one and use it correctly can help reduce the risk of serious damage or injury from electrical shocks and fires. By looking at a diagram and understanding the various components of the circuit breaker, you can be sure you have the right protection for your electrical system.
