How many feet for ground rod is required on most residential services?

Most residential services typically require a ground rod that is at least 8 feet long. This length ensures proper grounding to reduce the risk of electrical shock and system failures. The rod should be made of conductive materials, such as copper or galvanized steel, and must be driven into the ground to a depth that allows for adequate electrical contact. Local codes may vary, so it's important to check specific regulations in your area.
