What Is BX Cable?<\/h2>\n
\\n<\/p>\n
BX cable<\/strong> (also called armored cable<\/strong>) is an older but still widely used wiring method. It consists of:<\/p>\n \\n\\n<\/p>\n Insulated conductors<\/strong> inside<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Flexible metal armor<\/strong> on the outside, usually aluminum or steel<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n In many cases, the armor itself can serve as the grounding path<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n Typical Uses:<\/strong><\/p>\n \\n\\n<\/p>\n Exposed runs in basements, garages, and industrial\/commercial spaces<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Areas where wires need mechanical protection<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Installations that must comply with local code requirements for armored cable<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n\\n<\/p>\n \\n<\/p>\n Romex<\/strong> is the brand name for NM (non-metallic) cable<\/strong>, the most common residential wiring today. It consists of:<\/p>\n \\n\\n<\/p>\n Insulated conductors<\/strong> (hot, neutral, and ground)<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n A non-metallic PVC jacket<\/strong> for protection<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n A separate bare copper ground wire<\/strong> inside<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n Typical Uses:<\/strong><\/p>\n \\n\\n<\/p>\n Interior residential wiring in walls, ceilings, and floors<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Dry, protected spaces where the cable won\u2019t be exposed to physical damage<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Common circuits for outlets, lights, and appliances<\/p>\n \\n<\/li>\n \\n<\/ul>\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<\/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><\/div>\n \\n<\/p><\/div>\n \\n\\n<\/p>\n \\n<\/p>\n \\n<\/p>\n Tough metal armor protects against damage<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Provides built-in grounding in many cases<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Meets strict building codes in exposed installations<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n \\n<\/p>\n Heavier and harder to work with<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Requires special tools\/connectors<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n More expensive than Romex<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n \\n<\/p>\n Lightweight, flexible, and easy to install<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n More affordable for large projects<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Ideal for residential interior wiring<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n<\/p>\n \\n<\/p>\n Not permitted in exposed or damp areas<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Outer sheath can be damaged easily<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Not as durable as armored cable<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n\\n<\/p>\n \\n<\/p>\n Use BX cable<\/strong> when wiring in exposed areas like basements, garages, and commercial spaces where the cable needs mechanical protection. Many local electrical codes require armored cable in these situations.<\/p>\n \\n<\/li>\n \\n \\t<\/p>\n Use Romex cable<\/strong> for most residential interior wiring, such as outlets, switches, and lighting circuits in walls and ceilings. It\u2019s faster and cheaper for standard applications.<\/p>\n \\n<\/li>\n \\n<\/ul>\n \\n\\n<\/p>\n \\n<\/p>\n When comparing BX vs Romex wiring<\/strong>, the choice depends on your application and local code requirements. BX cable<\/strong> provides superior durability and safety in exposed environments, while Romex (NM cable)<\/strong> is the go-to choice for typical residential wiring inside walls.<\/p>\n \\n<\/p>\n \ud83d\udc49 Always check with your local electrical code<\/strong> before installation, and if you\u2019re not experienced with electrical work, hire a licensed electrician to ensure safety and compliance.<\/p>\n “}]}],”section_settings”:””},”scripts”:{},”css”:{},”css_page”:””,”template_setting”:{“settings”:{“id”:”settings”}},”template_setting_top”:{},”page_setting”:{“settings”:[“lock-mode-off”]},”post_type_setting”:{“settings”:{“image”:”https:\/\/totcables.com\/wp-content\/uploads\/2025\/09\/bx-vs-romex-wiring.webp|394|700|11547″,”excerpt”:”When it comes to residential and commercial wiring, two common options are BX cable and Romex cable.
