Aunque pueda parecer una pregunta de examen, es importante conocer esta informaci\u00f3n al comprar tomacorrientes el\u00e9ctricos, planificar la remodelaci\u00f3n de la casa o determinar la seguridad de su casa antigua. En t\u00e9rminos generales, todos los enchufes el\u00e9ctricos pertenecen a dos familias b\u00e1sicas, y una vez que entienda esas familias, le ser\u00e1 bastante f\u00e1cil navegar por el complejo universo de los tomacorrientes el\u00e9ctricos.

Un enchufe sin tierra de dos clavijas se denomina tipo Nema 1-15, y el enchufe con tierra de tres clavijas se llama tipo Nema 5-15. Los enchufes con tierra son tomacorrientes est\u00e1ndar de tres clavijas que tienen un pin adicional redondo de conexi\u00f3n a tierra. Los enchufes con tierra se dividen en varias categor\u00edas seg\u00fan el voltaje y los amperios, como los enchufes de 120V (15A y 20A).<\/p><\/blockquote>\n<h2>Las Dos Variedades B\u00e1sicas de Recept\u00e1culos El\u00e9ctricos<\/h2>\n<p>La pregunta \u201clos recept\u00e1culos el\u00e9ctricos vienen en cu\u00e1les dos variedades b\u00e1sicas\u201d se responde de dos maneras comunes, y ambas son correctas dependiendo del contexto:<\/p>\n<h3>Respuesta 1: Por conexi\u00f3n a tierra \u2014 sin conexi\u00f3n a tierra vs. con conexi\u00f3n a tierra<\/h3>\n<table>\n<thead>\n<tr>\n<th>Variedad<\/th>\n<th>Clavijas<\/th>\n<th>Tipo NEMA<\/th>\n<th>Estado en Hogares Modernos<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Recept\u00e1culo sin conexi\u00f3n a tierra<\/strong><\/td>\n<td>2 clavijas<\/td>\n<td>NEMA 1-15<\/td>\n<td>Obsoleto \u2014 se encuentra solo en casas antiguas<\/td>\n<\/tr>\n<tr>\n<td><strong>Recept\u00e1culo con conexi\u00f3n a tierra<\/strong><\/td>\n<td>3 clavijas<\/td>\n<td>NEMA 5-15 (y 5-20)<\/td>\n<td>Est\u00e1ndar \u2014 requerido para construcci\u00f3n nueva<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Tiene dos ranuras planas, por lo que el tomacorriente sin conexi\u00f3n a tierra de dos clavijas se conoce como un enchufe Tipo A.

Other classifications could be made vertically. The types of electrical receptacles that are commonplace today include: NEMA 1-15 (now obsolete 2-prong), NEMA 5-15 (standard 15-amp 3-prong outlet), NEMA 5-20 (20 amps with T-shaped hole), NEMA 6-15\/6-20 (240 volts tools), NEMA 14-30 (for electric dryers) and NEMA 14-50 (for electric range and recreational vehicle). Using special kinds of outlets provides additional advantages.<\/p>\n<h3>What are the two types of outlets that are found in an electrical system?<\/h3>\n<p>In electrical systems, there are two main varieties of outlets: the 120-volt outlets (the general-purpose electric outlets which are used for powering small devices such as lamps, electronic gadgets and other household equipment) and the 240-volt outlets (which are high-power outlets for home appliances such as dryers, ovens, air conditioners and EV chargers). The other way of identifying the two different types of outlets can be through grounding which refers to two types of outlets namely two-prong ungrounded outlets (found in older homes now considered obsolete) and three-prong grounded outlets (the current standard). They basically refer to the two distinct ways in which devices consume electricity from different types of outlets.<\/p>\n<h3>What are the two types of electrical systems?<\/h3>\n<p>Almost everyone talks of two kinds of electric systems namely, single-phase and three-phase systems. Single-phase systems (usually 120\/240 volts) are utilized in most residences. They have two hot conductors and one neutral wire. Three-phase systems (208 volts or 480 volts) are utilized in industrial and commercial settings to deliver higher amounts of power more effectively and run heavy motors. Residential installations almost always rely on single-phase electricity. There may be a few instances where a household may use some form of three-phase electric equipment such as a water well pump, a workshop, or a solar inverter.<\/p>\n<h3>What are the two basic categories of electrical switches?<\/h3>\n<p>Electrical switches fall under two primary classifications: the single-pole switch that allows control of one electrical load from a single position and the three-way switch that gives control of an electrical load from two locations. Other classifications exist, among them the four-way switch (which is used when controlling a light from three or several locations) and special-type switches such as smart switches, timers, and dimmers. However, single-pole and three-way switches remain the two most important types of electric switch. The single-pole switch consists of two terminals, while the three-way switch is composed of three terminals.<\/p>\n<hr \/>\n<h2>Referencias<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.nema.org\/\" target=\"_blank\" rel=\"noopener\">NEMA (National Electrical Manufacturers Association)<\/a> \u2014 The standards body that defines the NEMA receptacle configuration system (1-15, 5-15, 6-15, 14-30, 14-50, etc.) used throughout North America.<\/li>\n<li><a href=\"https:\/\/www.nfpa.org\/codes-and-standards\/all-codes-and-standards\/list-of-codes-and-standards\/detail?code=70\" target=\"_blank\" rel=\"noopener\">NFPA 70 (National Electrical Code)<\/a> \u2014 The code that governs receptacle requirements, including GFCI protection locations, tamper-resistant outlets, and 4-wire 240V circuits.<\/li>\n<li><a href=\"https:\/\/www.ul.com\/resources\/plugs-and-receptacles\" target=\"_blank\" rel=\"noopener\">UL Standards for Plugs and Receptacles<\/a> \u2014 UL 498 covers the safety requirements for attachment plugs and receptacles sold in the United States.<\/li>\n<li><a href=\"https:\/\/www.osha.gov\/electrical\" target=\"_blank\" rel=\"noopener\">OSHA Electrical Safety<\/a> \u2014 U.S. workplace safety guidance on receptacles, grounding, and GFCI requirements.<\/li>\n<li><a href=\"https:\/\/www.energy.gov\/energysaver\/operating-gfci-outlets-and-switches\" target=\"_blank\" rel=\"noopener\">U.S. Department of Energy \u2014 GFCI Outlets<\/a> \u2014 Practical guidance on how GFCI receptacles work and how to test them.<\/li>\n<li><a href=\"https:\/\/www.leviton.com\/en\/products\/receptacles\" target=\"_blank\" rel=\"noopener\">Leviton Receptacle Catalog<\/a> \u2014 Manufacturer reference showing the range of receptacle types, from basic 15A outlets to GFCI, TR, and USB models.<\/li>\n<\/ul>\n<hr \/>\n<h2 id=\"conclusion\">Conclusi\u00f3n<\/h2>\n<p>So, what are the two general types of electrical outlets? The simple answer is ungrounded (2-prong) and grounded (3-prong), or more simply put, 120V general purpose and 240V heavy duty. This makes the conclusion very clear:<\/p>\n<ul>\n<li>For everyday use, go for grounded 15 or 20 amp receptacles, as they are inexpensive, safe and compliant.<\/li>\n<li>For wet locations (bathroom, kitchen, garage, outdoors) you need to use GFCI outlets, as they can save your life and are required by the code.<\/li>\n<li>For heavy machinery use proper 240V NEMA outlet instead of modifying 120V outlet for those appliances.<\/li>\n<li>In case of renovation of old building, make sure you replace old 2-prong ungrounded outlets with grounded outlets (or GFCI protected).<\/li>\n<\/ul>\n<p>Thus, no matter where you want to buy a receptacle you have an idea where to begin.<\/p>","protected":false},"excerpt":{"rendered":"<p>Whether you are rewiring your house, changing an outlet, or just curious about the various electrical outlets in the room, you might be interested in knowing about the two different kinds of electrical outlets.
