Core Viewpoint - The introduction of the new national standard for household extension sockets aims to enhance safety measures in response to the increasing use of electrical appliances and the associated risks of overload and fire hazards [1][3][23]. Group 1: New National Standard Overview - The new standard, GB 2099.7-2024, will be implemented starting August 1, 2025, and is designed to enforce stricter safety regulations for extension sockets used in households and similar environments [2][18]. - Key updates include the addition of outdoor-specific products such as charging sockets for electric bicycles and vehicles, which must now meet requirements for waterproofing, anti-crushing, vibration resistance, and overcharge protection [3][5][7]. Group 2: Safety Enhancements - The new standard introduces specific power limits for different types of extension sockets: standard sockets must not exceed 4kW, while those for electric vehicles can go up to 8kW, and furniture-mounted sockets are limited to 2.5kW [7][9]. - Enhanced safety features include mandatory overcurrent protection for sockets with four or more outlets and the requirement for insulation protection on built-in plugs to prevent electrical hazards [7][12]. Group 3: Market Implications - The transition to a mandatory national standard signifies a shift in regulatory enforcement, providing consumers with greater assurance of safety when purchasing extension sockets from legitimate sources [16][18]. - The new standard is also positioned as the world's first international standard specifically for household direct current sockets, which could enhance China's technological influence and support the promotion of low-carbon energy systems [22][23].
