What is Type MC Cable permitted for when it comes to underground installation?

Type MC (Metal Clad) Cable is designed for various applications, but when it comes to underground installation, it's specifically permitted for direct burial under a building. This is due to its construction, which includes a metal armor that provides physical protection to the conductors inside. The metal armor helps safeguard the cable from potential damage caused by soil pressure, moisture, and other environmental factors commonly found in underground installations.

While Type MC Cable can be installed in conduits, in wet locations, or may sometimes need additional protection depending on site conditions and local codes, the direct burial under a building distinguishes it as an appropriate choice for specific underground applications. In this context, its ability to endure the challenging environment of direct burial, along with compliant installation practices and local regulations, makes it especially suitable for applications where protection is crucial.
