Understand what an electrical short circuit is and how to avoid it
What is an electrical short circuit
An electrical short circuit occurs when there is an extremely high flow of electric current in a circuit that is not prepared to handle such a load. A simple example of this situation is when a metal wire is placed in an outlet: the result is a short circuit that can be either low-level or violent, with bangs, explosions, and sparks.
It is worth noting that short circuits are one of the main causes of fires in poorly constructed or poorly maintained electrical installations, which have constant electrical movement.
Usually, sizing errors and exposed wires are the main causes of short circuits in residential, commercial, and industrial environments.
How to avoid an electrical short circuit
The installation of fuses and circuit breakers in places with high electric current is a common practice to avoid a short circuit in houses, apartments, stores, and industries.
Circuit breakers deserve special mention for their important role in detecting faults in the electric current, functioning basically as automatic switches that prevent short circuits.
Fuses, on the other hand, become unusable when a sudden interruption occurs and must be replaced immediately. A circuit breaker can be reset automatically.
Prevention tips
A very simple way to avoid a short circuit is not to overload an outlet. Connecting the television, radio, computer, cell phone charger, and several other devices to the same point is not a good idea, as the risk of a short circuit increases considerably and can even damage the devices.
It is worth highlighting that, even with adapters and extensions, the risk still exists.
A good tip is to perform periodic maintenance on the entire electrical system. Specialized technicians can easily identify overloaded points, imperceptible faults, as well as all wiring, worn-out outlets, and the best solutions to solve the problems.
How to identify an electrical short circuit
You know that burning smell that we don’t know where it’s coming from? Be careful, as this is a strong indication of an electrical short circuit.
To identify other signs, pay attention to:
- Outlets with black stains (which may be burned)
- Exposed wires that look old
- Light bulbs that frequently burn out in the same spot
- Sudden power interruption for no apparent reason (such as storms, lightning, or blackouts)
The tip is to stay alert to the signs mentioned above and make conscious use of light bulbs, outlets, and electrical devices. Avoiding a short circuit can mean safety and peace of mind for all users, as well as savings on the electricity bill.
