Trench and cable laying
Firstly, it is important to determine the depth and routing of the trench to ensure compliance with local codes and safety standards. The recommended depth for residential applications is typically around 12 inches, but it is important to check your local codes for specific requirements. If you plan to install a single or multi-wire branch circuit, the National Electrical Code specifies a minimum cover of 12 inches for GFCI-protected circuits with 20 amperes or less, while non-GFCI circuits require a minimum of 18 inches.
Rent a gas-powered trenching machine or a walk-behind trencher to dig the trench from the house to the garage. Manual digging may be required around obstacles or in tight spaces. After completing the trench, lay caution tape along its entire length to serve as a warning for future digging.
The next step is to lay the UF (underground feeder) cable, which is designed to withstand direct burial and moisture exposure. Bury the cable directly in the ground, ensuring that any exposed portions above ground are protected with a conduit. At both the house and garage ends, install a three-quarter-inch-diameter plastic conduit to shield the cable as it enters the structures. Use a propane heat gun to bend the conduit to match the foundation or wall contours.
Finally, connect the underground wiring to your home's electrical system by creating an entry point through the house wall into the basement. Pull the cable to the main electrical panel and secure it with cable staples. Ensure that all connections are secure before backfilling the trench with excavated soil. Schedule a final inspection with your local building department to ensure compliance and safety.

Cable protection
Firstly, it is important to determine the type of cable and conduit required for the installation. A licensed electrician should be consulted to ensure the correct choice of cable and conduit, which will depend on factors such as local codes, cable rating, and the presence of wet or damp locations. For instance, NMD90 is rated for dry locations, while THWN wires are suitable for wet locations.
Secondly, careful planning of the cable routing and installation is essential. This includes maintaining proper depth and support for the cable. The National Electrical Code (NEC) specifies minimum burial depths for conduits, which vary depending on the specific circumstances. For example, a minimum cover of 18" is required for direct burial non-metallic raceways, but this can be reduced to 12" for residential branch circuits with specific conditions.
Additionally, the cable should be securely fastened and supported at regular intervals. NM-B cable, for instance, must be secured within 12 inches of boxes and every 4-1/2 feet along its length. It is also important to follow local code requirements for cable routing, such as maintaining a minimum distance from the garage floor due to the potential presence of gasoline or oil.
Furthermore, the use of protective measures such as conduit and nail plates is important. Conduit, such as PVC or metal, provides a protective covering for the cable, especially where it enters the garage and house structures. It can also be used to transition from one type of cable to another, providing additional protection. Nail plates are protective metal plates that prevent cables from being damaged by nails or screws when they are run through studs.
Regular inspection and maintenance of the electrical wiring and cables are also essential for cable protection. This includes checking for signs of wear, water damage, or any other issues that could compromise the system's integrity. By addressing any concerns promptly, you can maintain a safe and functional electrical system in your attached garage.
