This rating depends on the total floor area of the home and the intended use of <strong>electrical appliances<\/strong> and the estimation of simultaneous power demand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following is established: <strong>Basic Electrification (EB)<\/strong> as the minimum required by the REBT, applicable to homes with floor areas of less than 160 m\u00b2 and where intensive use of high-power appliances is not anticipated. For this rating, the minimum rated power is 5,750 W (25 A). <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On the other hand, the <strong>High-Voltage Electrification (EE)<\/strong> It is mandatory not only for homes with a floor area exceeding 160 m2, but also for those that, regardless of their size, are designed to include high-energy-consumption systems, such as a standalone dryer, central heating, or central air conditioning. In this case, the <strong>residential electrical system<\/strong> It must provide for a minimum of 9,200 W (40 A). A defining criterion is that the mere need to install an additional circuit beyond the five required basic circuits automatically raises the rating to EE.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Partes_de_una_instalacion_electrica\"><\/span>Components of an Electrical System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">From a technical standpoint, the facility is divided into two main sections:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Electrical Connection Installation<\/strong> (from the public grid to the home).<\/li>\n\n\n\n<li><strong>Indoor Electrical Installation<\/strong> (internal distribution).<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/blog.structuralia.com\/wp-content\/uploads\/2026\/02\/partes-de-una-instalacion-electrica.jpg\" alt=\"\" class=\"wp-image-10096\"\/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Instalacion_electrica_de_enlace\"><\/span>Electrical Connection Installation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is the section that connects the distribution network to the building's internal system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Rush.<\/li>\n\n\n\n<li>General safety measures.<\/li>\n\n\n\n<li>Meter or counter.<\/li>\n\n\n\n<li>Individual branch circuit to the electrical panel.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Its function is <strong>transmit electrical energy<\/strong> safely to the main control and protection system.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Luz_de_compania\"><\/span>Nightlight<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">It is the<strong> electricity delivery point<\/strong> by the utility company.
