GFCIs protect you from electric shock. If your own continues to trip, call an electrician to find the source of the problem. A ground fault circuit interrupter (GFCI) trips when it detects a ground fault, or leakage of currents even as little as 5mA between the hot wire and the ground. When the gfci detects … Read more
Ever since introducing the ground fault circuit interrupter (GFCI outlet) in 1973, deaths from electrical shock have reduced by 83%. What is the ground fault circuit interrupter (GFCI) used for? A GFCI is a safety device used to protect human beings from electric shock. It is a fast-acting circuit breaker that cuts off the power … Read more
A circuit breaker can trip with little or no load for many reasons, such as circuit overload, grounds fault, short circuit, and a bad circuit breaker. You will need to confirm from a professional electrician that your breaker is bad before changing it. In this article, you will learn the signs of a faulty circuit … Read more
A molded case circuit breaker (MCCB) is a type of breaker that protects electrical circuits from overcurrents arising from overload, short circuits, or faulty wiring. It is like a miniature circuit breaker (MCB), however, MCCB has higher features. Molded case circuit breakers have a higher current rating of up to 2500 amp and an adjustable … Read more
A miniature circuit breaker is a safety switch that protects an electrical circuit from overcurrent or power surge. It is a protective device that interrupts the circuit when there are high currents.The primary function of a miniature circuit breaker is to protect an installation or branch circuit against high current arising from overload or short circuit. … Read more
An oil circuit breaker is a type of breaker that uses oil as an insulation medium for arc extinction. It is an essential device in the power system that uses insulating oil as an arc quenching medium. Oil circuit breakers use fixed and moving contacts for in circuit protection in both substations and transformers Each … Read more
An SF6 circuit breaker is a device that uses sulphur hexafluoride gas as an arc quenching medium. It is the type of circuit breaker used to protect power systems, electrical grids, and distribution stations. SF6 gas has strong electronegativity and arc quenching properties, making them a better insulating medium than air and oil circuit breakers. … Read more
Maybe your circuit breaker trips always and you want to know if the device has gone bad! A breaker can go bad, but rarely. A tripping breaker can be a warning sign of overload, short circuits, wrong wiring, ground faults, and a bad breaker. You need to find out what is tripping the receptacle before … Read more
Though we have different types of circuit breakers, they all protect electrical devices. Circuit breakers protect electrical equipment from short circuits, over-currents, fire outbreaks, electric shocks and ground faults. It is a must-have receptacle for every homeowner as required by the National Electrical Code. Circuit breakers come in varying sizes and models, ranging from the … Read more
Most times, when there is a power surge or circuit overload, the circuit breaker trips to prevent hazards. Circuit breakers play some protective roles in our power system, ranging from circuit protection to shield from electric shock. It is a must-have relay in our homes. In this article, we will learn about electrical circuit breakers, … Read more
