\ud83c\udfe0 What Is a Domestic Wire?<\/h2>\n
\\n<\/p>\n
A domestic wire<\/strong> is an insulated conductor used to transmit electricity within a home. It connects your main electrical panel<\/strong> to switches, sockets, lights, air conditioners<\/strong>, and more. These wires are optimized for low- to medium-voltage applications<\/strong> (usually 300V to 750V), and must be flame-retardant<\/strong>, durable<\/strong>, and safe<\/strong> for indoor use.<\/p>\n \\n<\/p>\n Domestic wire is a subcategory of building wire, but is specifically designed for the residential environment<\/strong>.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/thead>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/tbody>\n \\n<\/table>\n \\n<\/p>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n\\n<\/p>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/thead>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/p>\n \\n<\/p>\n \\n<\/tr>\n \\n<\/tbody>\n \\n<\/table>\n \\n<\/p>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n<\/p><\/div>\n \\n\\n<\/p>\n \\n<\/p>\n Domestic wire must meet national and international safety standards.

Some codes limit aluminum use indoors.<\/p>\n \\n\\n<\/p>\n \\n<\/p>\n 2.5 mm\u00b2 copper wire<\/strong> is standard for most 220V socket circuits in many regions.

Domestic wire is typically lower voltage, less robust, and easier to install than industrial cables which often require higher protection levels and insulation ratings.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n At TOT Wire & Cable<\/strong>, we supply high-quality PVC and XLPE insulated domestic wires that meet IEC, BS, NEC, and GB\/T standards.
