When you buy a house, or even when you do a renovation, it is very likely that you will need to take into account the redoing of the electrical system.
It will be necessary to redo the electrical system if it is not up to standard and consequently it can be dangerous as well as expensive, since an obsolete electrical system will certainly not ensure the right energy efficiency, which is essential for respecting the environment and for containing the cost of bills.

When is it time to redo the electrical system?

It is time to renovate the electrical system , if the latter is not CEI – Italian Electronic Committee certified. The law requires that an energy certificate indicating the energy performance of the property be attached to the documents for the purchase or rental of a home.

Even in all cases where the electrical system is damaged due to the humidity present in many homes or simply worn out over the years, it is a good idea to replace it with a reliable electrical system.

Sometimes the opportunity to renew an old electrical system arises when reorganizing the furniture: the arrangement of light points and lighting will logically have to be adapted to the new arrangements of furniture and furnishings.

How to bring an old electrical system up to standard?

Rebuilding an electrical system   without breaking down walls is almost impossible, as it will be necessary to carry out masonry work to insert the corrugated pipes where the wires of the new system will pass.

An electrical system that complies with the law respects the following parameters:

– It must have a circuit breaker, which is essential for blocking the electrical flow in the event of electrocution. This is a switch with a differential relay that controls the leakage currents that can occur following a fault in the system or an appliance and in the dangerous event of contact with a live cable.
– It must have magnetothermal switches, which have the function of protecting the system from short circuits and overloads.
– The work must be carried out by professionals in the sector registered with the Chamber of Commerce.
– The cables must be balanced on the capacity of the electrical system.
– There must be an “earthing”, which disperses the electrical flow into the ground.
– The electrical cable modules must contain the various users in a differentiated manner.
The regulations for the compliance of a system allow for tax deductions if all the parameters are adjusted.

How much does it cost to redo an electrical system?

Naturally, the cost of an electrical system varies depending on the intervention, whether it is ordinary or extraordinary maintenance, and clearly based on the size of the surface to be covered. The interventions described above, for example, represent on average about a third of the overall cost for a latest-generation electrical system. Furthermore, it is not only necessary to take into account the masonry work itself but also the subsequent painting of the walls and other collateral interventions, in addition to the price of purchasing and installing the materials.

A compliant electrical system is essential for safety and environmental savings. Naturally, it will have costs proportionate to the size of the work. If you are interested in a home automation system, but the amount of costs and especially the masonry work scares you, we recommend a free quote for a wireless home automation system, applicable without any intervention on control units and electrical cables.
