En mi art\u00edculo <strong><a href=\"https:\/\/brainfiller.com\/es\/technical-articles\/date-on-the-arc-flash-equipment-label\/\">\u00bfFecha en la etiqueta de arco el\u00e9ctrico?<\/a><\/strong> A principios de 2024, me sumerg\u00ed en las etiquetas y fechas de arco el\u00e9ctrico, incluidos los requisitos de fecha de la NFPA 70E y los requisitos m\u00ednimos del NEC. Parece que esto va a cambiar.<\/p><p>La edici\u00f3n 2023 del NEC solo requer\u00eda la fecha en los equipos de servicio y los equipos alimentados por el alimentador con una potencia nominal de 1000 amperios o m\u00e1s. La norma NFPA 70E nunca ha requerido una fecha. Cada ciclo de revisi\u00f3n de la norma NFPA 70E generalmente tendr\u00e1 una opini\u00f3n p\u00fablica para incluir la fecha, y en cada ciclo se rechaza.<\/p><p>La secci\u00f3n 110.16 del NEC est\u00e1 pasando por una revisi\u00f3n importante y, tal como est\u00e1 actualmente, requerir\u00e1 que la fecha forme parte de la etiqueta cuando se requiera una.<\/p><p><strong>110.16 Se\u00f1alizaci\u00f3n de peligro de arco el\u00e9ctrico<\/strong><br \/>En las unidades que no sean de pozo, se deber\u00e1 aplicar en campo o en f\u00e1brica una marca permanente contra arco el\u00e9ctrico en los equipos de servicio y en los equipos alimentados por alimentadores, como tableros de distribuci\u00f3n, cuadros el\u00e9ctricos, paneles cerrados, paneles de control industrial, cajas de tomas de medidores y centros de control de motores que probablemente requieran inspecci\u00f3n, ajuste, servicio o mantenimiento mientras est\u00e9n energizados. La marca deber\u00e1 cumplir con 110.21(B), estar ubicada de manera que sea claramente visible para personas calificadas y estar de acuerdo con las pr\u00e1cticas aplicables de la industria, y contener la siguiente informaci\u00f3n.<\/p><p>1) La tensi\u00f3n nominal del sistema<\/p><p>2) El l\u00edmite del arco el\u00e9ctrico<\/p><p>3) La energ\u00eda incidente disponible o el nivel m\u00ednimo requerido de equipo de protecci\u00f3n personal<\/p><p>4) La fecha en que se complet\u00f3 la evaluaci\u00f3n.<\/p><p><strong>Mi comentario personal:<\/strong> Los puntos 1 y 2 son id\u00e9nticos a los puntos 130.5(H)(1) y 130.5(H)(2) de la norma NFPA 70E. El punto 3 es una versi\u00f3n simplificada de la norma NFPA 70E 130.5(H)(3) que proporciona una lista de m\u00e9todos para identificar los EPP con clasificaci\u00f3n de protecci\u00f3n contra arcos el\u00e9ctricos. Creo que el punto 3 tambi\u00e9n deber\u00eda incluir la distancia de trabajo, pero no lo hace. Quiz\u00e1s la pr\u00f3xima vez, para la edici\u00f3n de 2029.<\/p><p>El punto 4 requiere la fecha, lo cual es una adici\u00f3n bienvenida. \u00a0<\/p><p>\u00bfPor qu\u00e9 es importante la fecha? Adem\u00e1s de actualizar el an\u00e1lisis cuando se produzcan cambios en el sistema de distribuci\u00f3n el\u00e9ctrica que puedan afectar los resultados del an\u00e1lisis, la norma NFPA 70E 130.5(G) exige: <em>\u201cEl an\u00e1lisis de energ\u00eda incidente tambi\u00e9n deber\u00e1 revisarse para comprobar su precisi\u00f3n a intervalos que no excedan los 5 a\u00f1os\u201d<\/em> La fecha en la etiqueta es un recordatorio no tan sutil de cu\u00e1ndo empez\u00f3 a contar el tiempo de los 5 a\u00f1os.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>2026 NEC and Dates on Arc Flash Labels &#8211;
