Electrical installations, how to obtain conformity certification

Buildings of any kind, whether private or commercial, are equipped with electrical systems that hopefully comply with all safety standards. Having an electrical system that responds perfectly to the regulations on health and safety of the environment, in fact, allows not only to avoid all the legal problems related to non-compliance with the rules, but also to guarantee to their family members or their employees a safe life .

What happens, however, if you are not sure that the building has an electrical system according to law? Sometimes, for example, you buy an old house or notice the management of a store or a company without knowing anything about the status of its facilities. Yougenio is a home help and repair service aimed at facilitating the customer in the management and renovation of their home and office. Among the various services offered there is also the issue of certification of the electrical system , a license that serves to avert all current and future problems related to electricity.

In private homes, for example, such certification serves to monitor the status of the facilities that each day have to bear the kilowatt weight of large household appliances. Washing machines, tumble dryers, dishwashers, hair dryers and vacuum cleaners are just some of the major energy consumers in homes, and which weigh down the flow of electricity into a plant. If the latter is old or malfunctioning, you can risk very dangerous short circuits, or simply annoying black outs when there are more appliances turned on together. Also visible electrical sockets, to which the small household appliances or the wires of computer charges and other devices are attached, are very important to be checked. If a socket does not make good contact it could burn the charger attached to it, send sparks or produce small electric shocks to those approaching it.

Even in offices and companies , however, you should not joke with the regulations on electrical installations. Especially in companies with a strong digital component, where servers and computers are many and constantly working, the systems must be monitored at an even tighter pace to avoid problems.
For this reason, Yougenio makes available to the customer a service created by professionals, who go to the site and see the plant to decide whether to issue the license of conformity. If the plant does not deserve it, you can still make improvements to make it modern and efficient.

Release of the certification of conformity

But how does the certification of conformity for an electrical system made by the professionals of Yougenio work? The electricians have a deep knowledge of current legislation and undertake to keep up to date in case of changes or new regulations. Once they reach the place to be examined, the electricians take into consideration the consumption of large and small appliances or electronic devices. If the consumption is too high or there are disagreements it means that the plant is too old, so probably not up to standard.

second inspection is made on the general voltage in the visible sections. If the imbalances between the various sockets are too high it means that there is a big difference in tension between the places of the analyzed environment, so probably that the current arrives differently with each outlet.
If all evaluations give a positive result, the license is issued and the electrical system is declared perfectly compliant.

In the booking price of the service, however, are not included all the interventions aimed at improving facilities and trying to bring them to the acceptance threshold for the issue of certification of conformity. In fact, in order to bring the plant up to standard, very profound work must be done, including masonry work and reconstruction of partially disembodied environments to replace the electrical system.

Other times it happens that the earths are not sufficient in proportion to the voltage accumulated by the appliances of that environment, so you have to change the whole setting of the electrical system. In any case, Yougenio professionals are available to the customer to take care of his health and safety, allowing a transparent and simple way of viewing and booking the service.

PLANT ELECTRIC WHAT IS THAT

The electrical system in the commercial structures is a set of components, electromechanical and physical equipment, which allow the distribution and use of electrical energy.

For commercial structures we mean shops, warehouses, bars, exhibition areas, florists, hairdressing and beauty salons, bars, stores and similar, in particular they are open to the public.
The main standard to refer to for electrical installations in commercial structures is the CEI 64-8 standard, but it is not the only possible solution to obtain a system in a workmanlike manner, the installer will have to apply the necessary diligence and expertise in evaluating the particular circumstances of each plant.

Depending on the type and quantity of stored goods, it may be necessary to check whether the commercial structure is at greatest risk of fire: in this case it is necessary that the electrical system is designed by a professional registered in the professional register. The same, even if more rarely, is necessary in case of structures with danger of explosion.

In short, the design of the electrical system is necessary when:

  • structure at greatest risk of fire

  • the commercial area exceeds 200 square meters

  • the engaged power is greater than 6kW

In other cases the project can be arranged by the technical manager of the installation company. Up to 6kW of power supply the supply is single-phase 230V as for residential buildings, above the supply becomes three-phase 400V .

In general, the electrical system in the commercial structures is as follows:

  • delivery point with measuring group and overvoltage protection isolation system, located outside

  • general framework that can be unique for centralized plants, or distribution board for more complex plants

  • power and control circuits divided into the areas of greatest interest, for example interior lighting, external lighting, sockets, external or internal shop signboard, window lighting, automatic shutters and curtains, air conditioning

  • stabilized circuit for critical or ICT users, such as loudspeakers, modems or ADSL connections, telephone outlets or dect repeaters, computers and network equipment in general

  • anti-theft security circuit

  • video surveillance security circuit

  • access control circuits or driveways

  • emergency lighting circuit

  • rephasing plant if necessary

  • network system for IT systems
