GFCI Won’t Reset, The Cause and How to Resolve It.

A ground fault circuit interrupter (GFCI) trips when there is leakage of current. If your GFCI won’t reset after tripping, it could be because: There is no power supply to the receptacle GFCI has gone bad Wrong connection Power turned off by the circuit breaker. But if the GFCI trips every time you reset it, … Read more

GFCI Tripping: The 5 Major Causes and How to Stop It.

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

Ground Fault Circuits Interrupters (GFCI), How They Work and How to Install Them.

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

Miniature Circuit Breaker (MCB): How It Works, Rating & Types.

A miniature circuit breaker (MCB) is an automatic switch that protects an electrical circuit from overcurrents or power surge. The term overcurrent refers to a faulty current that arises from short circuits, faulty wiring, and circuit overload. Both fuse and miniature circuit breakers protect electrical equipment from damage. However, MCBs are more advanced. Miniature circuit … Read more

Oil Circuit Breaker Types and How to Maintain Them

Oil circuit breakers are a protective device that uses oil as an insulation medium for arc extinction. It is one of the oldest breakers that has its contacts inside the oil. The switchgear has fixed and moving contact, which helps in circuit protection, both in substations and in transformers Each time there is a faulty … Read more

What is SF6 Circuit Breaker

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 systems. Sulfur hexafluoride gas has strong electronegativity and insulating properties, making them a better option than air and oil circuit breakers. Types … Read more
