Electrical breakdowns: The 3 most common electrical faults
What is an electrical fault?
An electrical fault is basically any abnormal electrical current within an electrical power system. An electrical fault occurs when the electrical wiring malfunctions or deteriorates and the natural flow of current through the circuit is obstructed. Unfortunately, faulty wiring is a relatively common - and potentially very dangerous - problem that many homeowners have to deal with.
Are electrical faults common in homes?
Electrical faults can be the result of a myriad of different and varied causes, or a combination of multiple factors. Most homeowners will at some point have to deal with some type of electrical failure in their electrical systems, even if it is a minor failure that poses no danger to the residents. The best way to ensure the safety of your family and your home is to familiarize yourself with the most common signs and causes of electrical faults.
Most common types of faults
Overvoltages
An overvoltage is a sudden increase in the voltage supplied to a circuit. This spike interrupts the normal flow of electricity within a circuit and causes permanent damage. The sudden increase in electrical energy overloads the circuits of electrical appliances and systems, creating an electrical fault. The resulting damage can range from minor malfunctions to catastrophic failures.
Short circuits
This contact causes the electrical current to travel a shorter distance than it is supposed to, and along the wrong path. This can be due to many causes, such as poor quality insulation, human error, power surges, accidents or conductor failure, among others. Short circuits can be very dangerous because they can cause fires or potentially fatal electric shocks.
Open circuits
An open circuit fault, as the name implies, occurs when there is an interruption or break in the circuit. This may be due to frayed or damaged wires that break, blown fuses or broken conductors. The current flowing through the circuit is interrupted and the power fails. It can also be inconvenient and problematic in homes. A visit from an electrician to assess the condition of your electrical installation can save you money and time.
