A circuit breaker trips when the current traveling through the circuit exceeds the rating of the breaker, causing it to become warm and spring open. This occurs when too many electrical devices are plugged into a single circuit. Moving some of the devices to other circuits should relieve the problem.
Circuit breakers in the home are often rated for 15 or 20 amperes. With 120-volt service, this means they have a limit of 1800 or 2400 watts, respectively. However, circuits should only run at 80 percent capacity for long periods, so if a circuit is loaded near its maximum, it may cause the breaker to trip.Learn More
A relay switch runs by sending electricity through an electromagnet in order to close or open a secondary circuit. The metal arm of the secondary circuit has a spring that is overpowered by the magnetic attraction created when power flows through the electromagnet. This attraction is what affects the circuit.Full Answer >
To change a circuit breaker, switch off the main circuit breaker, and unscrew the load terminal wire. Remove the old breaker, and reverse the sequence used to remove it to install the new one. Use a voltage tester, a screw driver, and a new circuit breaker to complete this task.Full Answer >
The common term for electrical pressure is voltage. Voltage is defined as the amount of electrical pressure that results in 1 ampere given a resistance of 1 ohm, according to Bay Electric.Full Answer >
Double-pole circuit breakers, also known as two-pole breakers, feature a combination handle that makes it possible for both phases of the breaker to trip if a short is detected on either side. The tripping has the effect of cutting the flow of power into a home’s wiring. Thus, the gadgets are safeguards against entry of excess current into a circuit.Full Answer >
