In which locations is Type AC cable permitted to be installed?

Type AC cable, also known as Armored Cable, is primarily designed for use in dry locations. This type of cable is constructed with an outer metallic sheath that does provide mechanical protection but does not offer protection against moisture and is therefore not suitable for installation in wet or outdoor locations.

The distinct nature of Type AC cable’s insulation and coverings makes it ideal for dry indoor environments where it is less likely to be exposed to moisture. Installing it in wet locations could lead to insulation failure and potential safety hazards due to water ingress.

Therefore, acknowledging the specific usage of Type AC cable highlights why it is permissible in dry locations, as this context ensures safety and compliance with electrical codes.
