In this article, we\u2019ll break down the meaning, structure, and common applications<\/strong> of UF-B cable so you can make an informed choice for your next electrical installation.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n UF-B<\/strong> stands for Underground Feeder, Type B<\/strong>. It is a non-metallic sheathed electrical cable<\/strong> designed to carry power underground and in wet locations<\/strong> without requiring a conduit.<\/p>\n \\n<\/p>\n This type of wire features:<\/p>\n \\n\\n<\/p>\n Solid copper conductors<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Individual insulation for each conductor<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n A rugged PVC outer jacket<\/strong><\/p>\n \\n<\/li>\n \\n \\t<\/p>\n A bare copper ground wire<\/strong><\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n Unlike standard indoor cables such as NM-B (Non-Metallic)<\/strong>, UF-B wire is specially designed to withstand moisture, corrosion, and direct burial<\/strong> in soil.<\/p>\n \\n\\n\\n<\/p>\n \\n<\/p>\n Let\u2019s break down the components of a typical UF-B cable:<\/p>\n \\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<\/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 UF-B cable is commonly used in residential, light commercial, and agricultural<\/strong> settings.
