How should electrical cables be properly secured in an installation?

Using cable ties, staples, or straps is the most effective method for securing electrical cables during installation. This approach ensures that the cables are held firmly in place, reducing the risk of damage from movement or environmental factors. Proper securing methods help maintain organization and prevent tangling, which can lead to complications in future maintenance or troubleshooting.

Moreover, securing cables adequately is crucial for compliance with electrical codes and standards, which often mandate the proper support and securing methods for safety reasons. Cables that are not secured properly may become hazardous, potentially causing electrical shorts or fire hazards.

The other methods listed, such as leaving cables loose to allow for flexibility or relying on duct tape, do not provide the necessary support and protection. Incorporating cables into the wall structure can be effective in some contexts, but it should be done in accordance with specific guidelines and practices to ensure safety and accessibility.
