GFCI’s protect you from electric shock. If your own continues to trip, call an electrician for troubleshooting and repairs. A ground fault circuit interrupter (GFCI) trips when it senses a ground fault, or leakage of currents even as little as 5mA between the hot wire and the ground. When the breaker senses the current leakage, … Read more
Ever since introducing the ground fault circuit interrupter (GFCI outlet) in 1973, deaths from electrical shock have reduced by 83%. The GFCI outlet or residual current drive (RCD) is a fast-acting circuit breaker that shuts off power once it senses a ground-fault. The receptacle works by comparing the input and output current from electrical appliances. When the … Read more
When a circuit breaker trips regularly with little or no load, users suspect a bad breaker. While this may be possible, it is not always true. An electrical panel can trip because of circuit overload, ground faults, over-currents, short circuits and other minor faults. Before you consider replacing your breaker box, always consult a licensed … Read more
A molded case circuit breaker (MCCB) is a type of breaker that protects electrical circuits from overcurrents arising from circuit overload, short circuits, or faulty wiring. They are almost the same as the Miniature circuit breaker (MCB) as they do the same work. However, MCCB is more advanced. It has a higher current rating of … Read more
A miniature circuit breaker (MCB) is an automatic switch that protects an electrical circuit from over-currents. The term over-current refers to a faulty current that arises from short circuit, faulty wiring, and circuit overload. Just like an electric fuse, a miniature circuit breaker does the same work of protecting electrical appliances from damage. However, they … Read more
Oil circuit breakers are the type of breaker that uses oil as an insulation medium for arc extinction. It is one of the oldest breakers that has its contacts inside the oil. When a fault arises, the contact opens through the help of the insulating oil, and an arc stuck in between them. Types of … Read more
SF6 circuit breaker is an extinguisher that uses sulfur hexafluoride gas to cool and quench the arc. It is the type of circuit breaker used to protect electrical grids, power stations, and distribution lines. Sulfur hexafluoride gas has strong electronegativity and insulating properties, making them a better option than air and oil circuit breakers. Advantages … Read more
A circuit breaker (safety switch) can go bad, and their common signs include: Burning smell from the circuit breaker box Burned parts Tripping light Circuit breaker hot to touch Damaged parts, for example, the switch. But before concluding that your circuit breaker is bad, there are other factors that can also cause your breaker panel … Read more
My circuit breaker keeps tripping with nothing plugged in. What could be the cause? You are not alone, Many people have experienced power tripping. A tripping breaker can be a sign of circuit overload, overcurrents, short circuits, or other minor problems. If one of your breakers keeps tripping with or without load, unplug the device … Read more
Although we have a different types of circuit breakers, they do the same work. A circuit breaker protects our appliances from short circuit, ground faults and power surge. It prevents electric shock and also protects our wiring system from a fire outbreak. Below are the different breakers we have. Types of circuit breakers Various kinds … Read more
