What is the appropriate method for securing cables in walls?

Securing cables within 12 inches of their entry point into boxes or fittings is essential for ensuring safety and compliance with electrical codes. This practice prevents potential damage to the cables from movement, minimizes strain at connection points, and helps maintain the electrical system’s integrity. It also reduces the likelihood of physical contact with sharp edges or other hazards near the entry point, which can lead to wear and tear over time.

Other options, while they may seem reasonable in context, do not align as closely with the key safety principles outlined in most electrical codes. For example, merely securing cables every 5 feet or after every junction box may not adequately address the increased risk of physical damage at entry points. Additionally, allowing cables to remain unsecured when running through conduit could lead to issues if the conduit is not properly secured or protected from movement, undermining the safety and effectiveness of the installation.
