Armored cable (AC) is a type of electrical wiring that is commonly used in residential and commercial construction to provide added protection against damage and hazards. AC cable is similar to non-metallic (NM) cable in that it contains two or more insulated wires and a bare copper ground wire, but it is also wrapped in a flexible metal sheath, typically made of aluminum or steel.
The metal sheath provides added protection against damage from impact, moisture, and other hazards. AC cable is often used in areas where the wiring is exposed or where there is a risk of damage from nails, screws, or other sharp objects. It is commonly used for wiring in unfinished basements, garages, and outdoor locations.
AC cable is available in different sizes and configurations, depending on the specific application. It is important to use the correct size and type of AC cable for each application to ensure safe and reliable electrical connections. Like other types of wiring, the use of AC cable is regulated by building codes, which specify the types of applications and environments where it is appropriate to use.
It is important to follow proper installation and safety procedures when working with AC cable, as it can present a hazard if not installed correctly. It is recommended to have an experienced electrician install and inspect the wiring to ensure that it meets local building codes and safety standards.
