Circuit breakers stop energy from flowing through a circuit if the current is too high. Electrical fires, shocks, and other injuries would be more common without circuit breakers.
Understand electricity before learning how a circuit breaker works. Electricity is electrical charge transfer between atoms. Electricity comes from natural gas, coal, or solar. Voltage, current, and resistance define electricity.
According to Electronicshub, voltage is the pressure needed to carry electric charge through a conductor. When current meets the conductor, resistance occurs. Some materials transmit electricity better than others because conductors have different resistances.
Hot, neutral, and ground cables make up your home’s wiring. Hot and neutral wires rarely touch, like ships at night. A high-resistance appliance maintains voltage safe by passing a current through it.
Sometimes the hot and neutral wires touch. It reduces current resistance, causing dangerous voltage and current levels and even fires, circuit breakers trip when voltage and current are too high. The trip disables the circuit until the problem is fixed.
In most cases, we blame a tripped circuit breaker on high-power-usage appliances like air conditioners, hair dryers, curling irons, and blenders. But suppose the circuit breaker trips, and no such devices are plugged in. Since nothing is plugged in, it is reasonable to question why the breaker keeps tripping.
Faulty electrical systems can cause fires, so it’s understandable if you’re worried about the potential danger to your home.
