Electrical installation overload: how to avoid it?

An electrical installation overload is a problem that happens frequently in many buildings, and puts safety and the life quality of its residents at risk. This type of damage happens with the excess of electronic and household appliances connected to the electrical grid at the same time.

Although it’s most common, not only older houses are subject to overload. Thus, a few caution steps must be taken to avoid that the problem aggravates and culminates in a short-circuit.

Identifying an eventual overload

The overload gives some signals that may suggest that an electrical maintenance is necessary. Be aware of frequent disarming of the circuit breakers, because this is the first alert that something is wrong. Burning of fuses, lighting failures and electrical conductors that appear to be dried, cracked, or perhaps with burnt smell, also require attention.

If there is a need to execute a repair, it will probably be necessary to acquire new electrical materials, which means, circuit breakers, outlets, wires, light bulbs and others.

Why do overloads occurr more often during the winter?

When temperature drops, it is normal to use devices such as electrical showers and heaters, for instance, for temperature control, but they require a higher current. Which means, the electricity used is more concentrated due to domestic heating. It causes a bigger incidence of overloads during the winter, and that’s why you must be extra careful on cold days.

How to prevent electrical grid overload?

Don’t wait up to look for an electrician or electrical engineer. Prevention is the cheapest and safest way of dealing with electrical grid related problems.

Avoid mess and don't cause electrical installation overload.

Avoid mess and don’t cause electrical installation overload.


  • Some problems may seem small, but should be solved with urgency, such as loose outlets, exposed wiring and bare wires.
  • Don’t plug too many devices into only one outlet and avoid using extensions, adapters, and T-plugs.
  • Look for a professional to execute an electrical assessment when installing more powerful equipment, such as stronger showers and air conditioning.
  • Purchase devices that are compatible to the electrical current of your residence.
  • Perform grid maintenance every 5 years to identify and repair any eventual existing problem.
