Electrical installation and risk of electric shock when building a house

Pay attention to electrical installation when building a house to reduce the risk of a disaster!

What work can you do by yourself in the field of electrical installation when building a house – a master craftsman is absolutely necessary as things could quickly become dangerous?

The construction of a new house – a likely costly investment in the future

If you have decided to build your dream house yourself according to your own wishes, as a builder you can quickly find a large investment. The prices for land are rising rapidly, especially in city centers. Due to the many lapses in country’s legislation and in the economy, construction of buildings is also becoming more and more expensive. Many builders try to reduce construction costs through their own work.


The construction site for new construction and renovation of real estate is a major source of danger for accidents that occur in connection with electrical power. However, accidents related to electric shock are more common in private households.


Pro tip

In consultation with the architect, experienced hobby craftsmen can create some trades in the new building project on their own. Particularly in the interior design, there are construction phases that can be carried out by skilled builders themselves. This includes, for example, wallpapering or laying floors with laminate or carpeting. The procedure is similar when buying a house , if an existing property is mainly renovated or modernized indoors.

What does the legislation say about electrical installations in the construction sector?

In building law, the legislation has clearly defined the individual trades. The area of ​​electrical installation in house construction is part of the most dangerous construction work. The craft work carried out here may only be carried out by an electrician who has a master craftsman’s certificate. Errors that occur when working on the house can have devastating consequences. Short circuit, overvoltage, cable fire or an electric shock can lead to considerable material damage if improperly carried out.

In the worst case, an accident on the construction site in connection with electrical power can even endanger the lives of those involved. The regulation stipulates that only electricians with a master craftsman’s certificate who are registered with the regional electricity suppliers are allowed to work in the respective power grid. Anyone who does not observe these regulations usually loses their insurance cover and then has to pay for any damage out of their own pocket.

What work can the builder, as a skilled craftsman, carry out to support the electrician?

If the electrical cables are reinstalled in a new building or when a house has been bought, there is still some work in which the landlord can participate in order to reduce the costs for the electrician somewhat.
The experienced hobby craftsman can also carry out the following work steps without an electrical specialist:

  • Chisel slots for the electrical cables
  • Lay cables under plaster
  • Place sockets under plaster
  • Laying lines and conduits
  • Pull wires and cables into conduits

During this preliminary work, it is crucial that the lines must not have any connection to the electrical circuit. If in doubt, the builder should consult the foreman from the electrical company if he is not sure whether there is a risk of electric shock during his work.

How is the connection to the circuit made for a new house?

As a general rule, the builder, who works for the electrical installation when building a new house, should discuss all of his work steps with the electrician in advance. The specialist will also have tips from their specialist knowledge ready, which will simplify the preparatory work for the client. When the work steps of the hobby craftsman are finished, it is imperative that the master from the electrical company checks all the work.

Only then can the electrician connect the new building to the electrical circuit with a clear conscience. If you keep this order of division of labor, both benefit. The electrician is finished with his work faster and the building owner can save some costs on the construction site through his participation.

In which environment do most electrical accidents occur?

The construction site for new construction and renovation of real estate is a major source of danger for accidents that occur in connection with electrical power. Here, however, the specialists from the electrical trade who are familiar with the regulations for dealing with electrical voltage are often at work. Accidents related to electric shock are more common in private households.

With the existing low voltage in the household of 220 volts and currents between 50 and 100 milliamps, the risk of life-threatening accidents in connection with electricity is quite high. Defective electrical devices, especially older devices, pose a very high risk. As a resident of a house, you are tempted to repair defective household appliances yourself. If not handled properly, this can lead to serious accidents with electrical power.

What measures should be taken in the event of an electrical accident?

In the event of an accident involving electrical energy in the household, the risk of electric shock should not be underestimated. In any case, in order to help an injured person, you should not endanger yourself.
This procedure must be observed in the event of an accident:

  • Turn off the power immediately
  • Alert the rescue service as soon as possible
  • With first aid, be careful not to become part of the electrical circuit yourself
  • Disconnect the injured person from the power source with a non-conductive object
  • When the injured person is disconnected from the electricity, place them in a stable position on their side
  • If there is no breathing, resuscitate the injured person until the rescue arrives

These measures are the best way to provide first aid to an injured person who has been affected by an electrical accident.

Conclusion:
When dealing with electricity, caution is always the best advisor. The tricky thing about electric current is that it is invisible and does not announce itself if it is used incorrectly. Electricity accidents or electric shocks happen in a split second. Whether on the construction site or at home, you should always be on your guard when dealing with electricity. In the event of a defective line or a device that no longer works, it is important to first switch off the fuse in order to interrupt the electrical circuit.

When it is certain that no more current is flowing from the grid, the device can be disconnected from the grid. Never repair defective electrical devices yourself. The manufacturer is responsible for this, and the defective electrical device may still be covered by the manufacturer’s warranty. If you open an electrical device yourself, you may endanger your life. In any case, the hobby craftsman loses his warranty claim against the manufacturer after opening the electrical device independently.
