This classification is specified by the National Electrical Code (NEC) and is reserved for supplies with defined outputs not exceeding 100VA (Volt-Amperes). The primary goal of Class 2 power supplies is to help mitigate electrical fires by limiting the maximum energy that can be utilized. They are widely used for lighting systems and automation which low-cost electric devices with basic wiring are preferred.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_a_Class_II_Power_Supply\"><\/span><b>What is a Class II Power Supply?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Double or reinforced insulation that provides additional protection against electric shocks characterizes a Class II power supply. Class II power supplies do not utilize a grounding conductor, which means they do not require a ground wire. Instead, two insulation layers separate the user and the electric current-carrying components in order to guard against electric shocks. Thus, two are sufficient to prevent the user from coming into contact with the live parts of the device.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Class_2_vs_Class_II_Power_Supply_8_Differences\"><\/span><b>Class 2 vs Class II Power Supply: 8 Differences<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\"><img fetchpriority=\"high\" decoding=\"async\" class src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2025\/03\/\u5fae\u4fe1\u622a\u56fe_20250312153513.png?quality=85&strip=all\" alt=\"Class 2 vs Class II Power Supply: 9 Key Differences  title=\" width=\"300\" height=\"207\" vs ii power supply: key differences title =\"\"><\/span><\/p>\n<p><span style=\"font-weight: 400;\">Let\u2019s take a closer look at the 9 key differences between Class 2 and Class II power supplies:<\/span><\/p>\n<table style=\"border-collapse: collapse;
