Electrical Safety: How to Prevent Electrical Accidents at Home

Published by on October 17, 2018

Do you think your home is well protected against electrical accidents? If you stop to think, in all probability you will find points where you can improve the electrical safety of your home .

It is vital that you take note of the advice and measures that we present below because electrical accidents can cause significant material loss and, in the worst case, physical damage to your family or yourself. On the other hand, remember that good home insurance protects you against this type of accident, greatly reducing its repercussions.


Electrical Safety Elements In The Home

What elements do you know to improve electrical safety at home? We have developed a selection of protective measures for electricity in the home. Some are part of the safety elements in electrical installations that normally come standard and others you can add yourself. You can also visit for appointing professionals in the field of maintenance of electrical appliances or elements.



When the electrical consumption exceeds a certain electrical intensity, the fuses “blow”, preventing the flow of current. Fuses prevent major breakdowns, usually fires in the home . It is important to note that it is necessary to change these elements each time they “jump”. This task is simple and they are changed in a similar way to a battery, making sure that the new fuse meets the same ampere values ​​as the previous one. Remember to follow the basic safety measures before carrying out any type of electrical manipulation:

Wear the appropriate insulating material, such as protective gloves.

Cut off the electricity to the general box.

However, if you are not sure how to carry out this task, it is advisable that you go to an electrician.

Circuit Breaker

It is based on exactly the same operation as fuses, with the advantage that it does not have to be changed every time it trips. Simply, the flow of the current is controlled raising and lowering it.

It is essential to agree with the electrician the intensity that the circuit will withstand , it will even allow you to save energy at home , since they will jump in case of excessive consumption.

Differential Switch

This device must be linked to the earth connection of the house building to guarantee the protection you need. Its function is to prevent accidents in case someone makes contact with parts of the circuit that have voltage, such as a loose wire.

Lightning Rod

It is a fundamental element to prevent storms from causing electrical damage in our home.

Socket Protector For Children

This is an electrical safety measure that is as simple as it is effective when it comes to preventing accidents when there are children in the home . We are talking about a plastic plug that fits perfectly in the sockets to prevent the little ones in the house from sticking their fingers in them, for example.

Tips To Improve Electrical Safety

Our home can pose electrical hazards, especially for the little ones, so it is essential to incorporate certain habits into our daily routine if we want to prevent electrical accidents:

Avoid using electrical appliances if you and / or your children have just gotten out of the shower.

Avoid the use of electrical appliances during the bathroom such as the hairdryer, the computer or the Tablet.

Do not leave children alone in a room that has unprotected outlets within reach.

Be careful to keep metal objects away from plugs such as scissors, tweezers, or punches that could be accidentally inserted.

In the event of a thunderstorm, unplug as many electrical appliances as possible.

Electrical Safety Standards

The technical instructions that every electrical professional must follow to guarantee the correct operation of the electrical circuit of our home are included in the Low Voltage Electrotechnical Regulation (REBT) . Let’s see the most relevant points:

Alternating current distributions must be 230V between phases . And, before installing an electrical circuit in a home, it is essential to know the design in advance, taking into account the power that it will withstand.

The electrical panel must be placed as close as possible to the main electrical outlet, next to the access door to the house and at a height of between 1.5 and 2 meters from the ground . Furthermore, it cannot be installed in spaces that require special security such as the kitchen or bathroom.

Independent circuits and branches must be protected by circuit breakers that can be used manually. These elements must protect the house against short circuits and overloads.

The individual branch pipes must have a nominal outside diameter of at least 32 mm. In addition, it is mandatory that the conductors are copper and a t ension 450/750 V . A particularity of the regulations is that they must be correctly identified by colors: the earth protector must be green and yellow, the neutral blue and the phases brown, black and gray.

It is mandatory that homes have a device that protects them from lightning.


Your home must have certain electrical safety elements installed in accordance with current regulations, such as, for example, magnetothermic switches, the differential and the lightning rod. In addition, it is essential that you follow the appropriate safety measures to avoid electrical accidents, such as placing protectors on the sockets if you live with children or cutting the power if you are going to handle cables.
