All electrical installations must be performed from an electrical design in order to ensure the safety of people and animals, the proper functioning of the installation, energy saving with loss reduction, and the conservation of property. In addition, the project must be designed for new installations and renovations to existing facilities.
In an electrical project the components of the installation are appropriately sized and specified, avoiding major problems in poorly performing installations such as the appearance of unwanted effects, equipment malfunction or damage, excessive expenses with poor or oversized components, need for further intervention, beyond accidents with electric shocks.
According to the National Institute of Meteorology, the area has a high incidence of lightning, stressing the importance of sizing or not a lightning protection system (lightning rod), designed to protect a building or structure against the effects of lightning. For the proper Pulse Power now the options are there.
Lighting should also be properly designed, ensuring the right level of lighting for each environment, taking into account the type of task, the age range of users, energy efficiency, among other factors.
After installation is complete, the project must be reviewed and updated to correspond faithfully with what has been done (“as built” or “as built” documentation), including single-line wiring diagrams, which are of fundamental importance.
This is the electrical installations for all establishments, regardless of installed power, building area, economic activity, number of workers, etc. The inexistence or outdated of these documents can lead to uncertainties and surprises that lead to undesirable events during maintenance or necessary installation interventions.
To start a work, we must always follow what was designed, this also applies to all electrical parts of buildings. There are professionals in the market specializing in electrical projects and professionals specializing in the execution of this electrical project. Let’s talk a little more about the importance of an electrical project in a work below.
What is an electrical project
The electrical project consists of determining materials, both in specification and quantity, as well as how the installations that require electricity after the work is completed, this goes for lighting and the outlet network. In electrical projects, the person responsible for the execution, usually an electrician, has all the information necessary to correctly perform the electrical installations of the work.
Whose responsibility for the project?
Every electrical project must be done by an expert qualified for this function, simpler projects the Civil Engineer and an Electrical Technician can do, but for more elaborate projects there is a requirement that is made by the Electrical Engineer, which requirement is determined by the body. CREA, which also requires the issuance of an ART (Certificate of Technical Responsibility) for that project is all because it is a project that demands a high responsibility, after all, if not well sized accidents can happen such as shocks, short circuits, among others and that can cause damage and even health risks to those who are using that facility.
Many people, especially when it comes to smaller works, despise electrical design, this is a very big and common mistake in our works today. Saving on the project can cost you money later on, does the electrical project determine the quantity and exact specification of each material to be purchased for your work, if you do not have a project how will you know this information? What will be your damage if the work stops because the electrician forgot to ask for 1m of cable? What if you buy something else? Surely this loss will be much greater than the amount you would spend on the project.
