Electrical circuits allow electricity to flow through copper wires as they’re effective conductors. But when there’s trouble with the wires, the electrical current can travel via an unintended route, resulting in what’s called a short circuit.
An electrical short circuit occurs when electricity doesn’t go where it’s designed to go. It’s when electricity travels via a low-resistance route or takes a shortcut – hence the term “short” circuit. This can occur when the current comes into contact with a conductive material that’s not meant to carry electricity.
There are two main types of short circuits: a “normal” short circuit and a ground fault short circuit.
Let’s take a look at the common causes of a short circuit:
Electrical wires come in non-conductive casings made of PVC. However, this casing can get damaged over time due to being chewed out by rodents or by screw punctures. When this occurs, the wire will be exposed, resulting in a short circuit.
Loose wiring increases the chances of a live wire coming into contact with a neutral wire. Loose connections can also increase the resistance, which can then cause the wire’s temperature to rise. This puts your property at risk of an electrical fire, an accident that happens more than 51,000 times per year, according to the Electrical Safety Foundation International (ESFI). If you notice loose connections, call a licensed electrician – do not try to fix it yourself.
When you plug an appliance into a socket, its wiring becomes part of the whole circuit. This means that any problems it currently has will also become the circuit’s problems. If there’s something wrong with the appliance’s wiring, its plug, power cords, etc., this can trigger a short circuit.
During a short circuit, the resistance will change, causing a sudden spike in electricity. This has the potential to do damage to the appliance, cause an electrical fire, or worse – electrocute you. The increase in temperature can also melt plastics or set flammable materials on fire.
Your electrical system comes with a circuit breaker, which is a device that cuts off the flow of electricity once it detects a short circuit. While your circuit breaker can be relied upon, it’s best to have it maintained to make sure it continues to do what it’s supposed to. With that said, be sure to schedule circuit breaker maintenance with your local electrician. Ideally, circuit breakers should be tested once every 1 to 3 years.
The key to keeping your property safe from electrical fires is by scheduling an inspection.
