When you need to run an electrical load, you turn to your breaker box for help. These protective devices have been around since the invention of electricity. But while they might look like a no-brain device, understanding how they work and how to choose the right breaker for the rated load can make you a … Read more
30 amp breakers are used to protect the circuit and appliances from overload, power surge, and electrical hazards. They come in different ratting and amperage such as 3A, 5A, 15A, 20A, 25A, 30A, 40 A 50 A and others. Different appliances require a different amp of breakers for protection. And the higher the device or … Read more
A motor circuit protector (MCP) is a type of circuit breaker used to protect electric motors from overload and short circuits. It is a protective device that offers protection to electrical equipment. Electrical motors play huge roles in electrical products as they are used to drive mechanical devices of any type, and such equipment needs … Read more
Just like other breakers, the square D QO breakers protect appliances from over-current and short circuits. It controls the flow of electricity and also cuts off faulty currents that can threaten the safety of the circuit. Circuit breakers come in different types and sizes, but they do similar work, which is over-current protection and prevention … Read more
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
GFCIs 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 the introduction of ground fault circuit interrupter (GFCI outlet) in 1973, deaths from electrical shock reduced by 83%. The GFCI is a fast-acting circuit breaker that interrupt power once there is a ground fault. It compares the input and output current from the electrical system and if there is an imbalance even as little as … Read more
When a circuit breaker keeps tripping with little or no load, many things can be responsible. These include: Circuit overload Ground fault short circuit Bad circuit breaker. But if you have confirmed from an electrician that your breaker is bad, replacing it is quite easy. In this article, you will learn how to replace a … 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 is an automatic switch that protects an electrical circuit from overcurrents or power surge. It is a protective device that trips when there is a fault current on a circuit. The term overcurrent refers to a faulty current that arises from short circuits, faulty wiring, and circuit overload. Both fuse and … Read more
