Electrical project who can be a designer? What is the descriptive memorial for the electrical project? Who can sign the electrical project? Is residential electrical design different from industrial electrical design? Which electrical installation software to use? These are the main questions among many about electrical design and the World of Electrical answers these questions now, come on guys
What is an electrical project?
Electrical projects are the compilation of all information regarding the electricity of an electrical installation, machine or equipment, this information can be in the form of electrical data tables, component list, electrical diagrams, component distribution schemes, part drawings, layout and etc.
When we think of electrical design, we immediately think of residential electrical design, which is usually a diagram with the distribution of cables, placement of sockets and lamps drawn on the floor plan of a house, building or shed.
Residential electrical project and industrial electrical project, is there a difference?
It is common to hear that the industrial electrical project differs from the residential electrical project due to the difference in the number of phases, a residential installation has one or two phases (single-phase and two-phase system) and an industrial installation has three phases (three-phase system), but this information is not correct, because one of the factors that define the number of phases of an electrical installation is the installed power, that is , the amount of equipment installed. Although it is unlikely to happen, a house can be so big and have so much equipment that a three-phase installation is necessary, but that will not characterize it as industrial.
What really differentiates a residential electrical project from an industrial electrical project are the characteristics of the installed equipment (such as the use of motors in the industry), the complexity of extra systems that are required in an industrial project (such as a system to detect and combat for example) and also the amount of load expected for the installation.
Descriptive memorial of an electrical project, what is it?
In an electrical project, there is no maximum amount of information, but there is the minimum information necessary for the electrical project to be acceptable according to the standards and inspection bodies such as city halls, fire departments and other bodies.
All information required by standards such as safety in projects required by NR10, technical standards NBR5410 Low voltage electrical installations, NBR5444 Graphic symbols for building electrical installations and others that are necessary, must be gathered in the project description, that nothing more is the written information and tables of the installation project.
Who can be an electrical designer?
Anyone with sufficient technical knowledge can perform calculations of electrical projects, make drawings, layout and create the tables of an electrical project, but only technicians and engineers registered with the competent class council which is CREA (Regional Council of Engineering and Agronomy) is who can effectively take technical responsibility for a project.
The technical responsibility of a project is conferred to a technician or engineer through ART (Annotation of Technical Responsibility), this ART is a document issued by CREA that links a project, work or service to a qualified professional, the professional linked to an ART becomes responsible for a specific project, work or service and in case of failures, answer for them.
Can civil engineers sign an electrical project?
Yes, civil engineers and even other engineering areas such as mechanics have a certain autonomy to take responsibility for electrical projects with CREA.
During the academic training, the civil engineer has several subjects related to electrical installations in his academic training. It is worth remembering that all engineering areas other than electricity engineers have limitations on the amount of load installed in the project for which they are responsible.
Software for electrical projects, is it worth it? Should I use it?
Without a doubt the vast majority of electrical projects are made in software, the large amount of information that the standards require in a project is easily corrected and verified by programs specialized in electrical projects, both programs for residential electrical projects, which are mostly more simple, as for programs for industrial electrical projects, which can be much more complex and automate a large amount of information and calculations that an industrial project must contain.
It takes much less time to carry out an electrical project using software, which makes the use of software nowadays almost mandatory.
With these questions answered is easier to understand the importance of electrical projects , the professionals of electricity increasingly interested in the theme electrical projects and still exists in the market a great need for professional who can read and interpret electrical projects.
