Diagram Circuit Breaker
Circuit breaker is an automatically operated switch that protects the appliances from short circuit or heavy load current.
Diagram circuit breaker. This circuit breaker wiring diagram illustrates installing a 20 amp circuit breaker for a 240 volt circuit. Circuit breakers snap into place onto one or both of the bus bars to provide power to the circuits. Leave that breaker on and have your helper plug the device into other receptacles.
The white wire is used for hot in this circuit and it is marked with black tape on both ends to identify it as such. The basic circuit breaker consists of a simple switch connected to either a bimetallic strip or an electromagnet. Without a circuit breaker you could find yourself dealing with household fires on a regular basis.
We will be using this simple diagram to discuss the components involved with the electrical operating sequence of a circuit breaker. This device is essential in a modern world that runs on electricity. If you don t see a circuit breaker labeled service disconnect or main in the panel it is likely in another.
This circuit breaker is likely to have the largest amp value and will be located either at the top or bottom of the panel. Turn off the power supply to the electrical panel. The hot wire in the circuit connects to the two ends of the switch.
A breaker circuit is an electrical switch that cuts off electrical flow in the event of a possible short circuit or overload. Single pole circuit breakers provide 120 volts and connect to just one hot bus bar. 4 repeat this process switching on room lights one by one and note the circuit breaker that controls each set of lights.
A neutral wire is not used in this circuit. These are all the symbols used for generic circuit breaker. Note all the ones controlled by that breaker.
