When building a building or home, as when renovating it, the electrical system is a detail that must be taken into account, to ensure the lighting and protection of the electrical appliances and the savings in monthly expenses.
Experts advise for a safe electrical installation, consider four aspects: 1) project, labor and materials; 2) design by a professional engineer, architect or technician; and 3) comply with the requirements expressed in the Regulations for Electrical Installations of the Argentine Electrotechnical Association; and 4) the execution by registered candidates.
“The materials to be used must be certified, complying with Resolution 169/18 of the Argentine Chamber of Commerce and Services and other legal requirements, which include cabinets for main and secondary boards; boxes for switch modules, outlets, pipes and / or cable channel, among others. They must be certified, under the IRAM (national) or IEC (international) standard, by an organization. They can be checked in the market because they must obligatorily display on the product, or on its packaging, the seal granted by the agency and next to it, the Electrical Safety Seal “, he told Infobae, Hugo Exposito, President of the Low Voltage Commission of the Argentine Chamber of Electronic, Electromechanical and Lighting Industries (Cadieel).

The total amount of a complete electrical installation, whether in a new building such as a used house or apartment, is estimated at around 10% of the cost of the square meter of construction, about USD 50 per covered meter, half corresponds to labor.
Carlos Foligna, electrical engineer and manager of promotion and dissemination of electrical safety of Conextube, told Infobae: “I recommend entering the website of Apse Argentina what has an updated list of professionals. I advise against improvising in an installation that is so necessary and at the same time risky that can cause fires in the event of short circuits and involuntary electrical shocks due to insulation failures, and put the lives of household members at risk ”.
“Regarding other faults caused by the network or the atmosphere, such as low voltage, cut and replacement of supply, switching overvoltages or by lightning, for each of these phenomena there are protections that are not mandatory, but are convenient. To avoid damage, I suggest disconnect electrical and electronic equipment when there are electrical storms or the mains voltage is so low that it hinders proper operation, and it can burn them if they persist for a long time, ”said Foligna.
Forecasts and prices
“In a home to be recycled, and more so if it is old, it is recommended to redo all the electrical installation, with its protections and components. The values of the cables range between $ 45 and $ 100 per meter, depending on the characteristic demanded by the installation ”, he told Infobae, Marcelo Vergagni, president of Industrias Erpla.
“It is very important in terms of safety to have an efficient grounding circuit, which consists of one or more javelins and the green-yellow cable that runs throughout the installation, connecting to the luminaires with metal casing and to all the outlets in its corresponding ground terminal. All the electrical appliances and other devices that have an IRAM 2073 3-pin plug, when plugged in, remain connected to the ground “Exposito said.
“Bathrooms and kitchens are the environments where you must be more careful because that is where they concentrate the greatest amount of risks within a house, but also parks, gardens and swimming pools, because many of their electrification and lighting installations do not meet the conditions minimum security ”, expanded the president of Cadeieel.

Vergagni, highlighted: “It would be beneficial for society and the industry if the Electrical Safety Law, which is in the Chamber of Deputies of the Nation, because it would increase prevention in homes ”.
Regarding the prices, the circuit breakers offer, according to the brand and the amperage, different prices, starting at $ 2,000 for national ones, and reaching more than $ 7,000 for imported ones. Thermal keys range between $ 500 and $ 1,500. Light keys start at $ 300, and smart keys start at $ 2,500 per unit. While wall lights and accessories start at $ 1,300. Sockets or plugs cost from $ 200 and up to $ 1,000 for modern designs with bright colors in gold or silver.
Adaptation for remote work
By spending more time at home due to the pandemic, many workers who began to do their homework remotely had to reconvert some environments, and adapt the electrical connection and sockets for various appliances. In the case of the use of multiple extension cords, those that are certified are recommended and require a good ground connection and the cut-off of the electrical supply to all loads, if they exceed 10 amperes.
“To save energy the advice is, first, use LED lamps to replace the old light sources; second, replace electrical appliances with others with high energy efficiency. Choosing more efficient equipment will translate into savings on your energy bill. In addition, it always helps to turn off the lights and equipment that are not used, ”said Exposito.
The biggest problem in this market is not the values and the dispersion between certified brands, but the unfair competition of manufacturers and marketers not duly registered that offer the products at ridiculous figures, deceiving the consumer and putting their lives at risk.
The current problem is the supply of raw materials, both domestic and imported (Foligna)
Carlos Foligna told Infobae: “Each factory was impacted in a different way. There was support from the State to overcome the forced immobilization of the activity. Little by little, with the gradual release, demand began to increase, until the fall compared to the previous year was reduced to a range of 20% to 30% in December, depending on the type of product. The current problem is the supply of raw materials, both national and imported ”.
I kept reading:
2020 closed with an inflation of 36.1%: in December it climbed to 4%
Martín Guzmán assured businessmen that there will be no devaluation jump in 2021
