How must electrical wires be installed in a residential setting?

In a residential setting, electrical wires must be secured and protected from physical damage to ensure safety and compliance with electrical codes. Proper installation prevents wires from becoming hazards, such as tripping risks or potential damage from contact with sharp objects or environmental factors. By securing wires, the risk of interference from foot traffic, pets, or other household activities is minimized, thereby reducing the chance of shorts, fires, or electrical shock.

Moreover, protecting these wires means they must either be placed within conduit, covered by walls, or otherwise shielded in a manner that meets the standards set by the National Electrical Code (NEC) and local jurisdictions. This practice not only preserves the integrity of the electrical system but also ensures that it operates efficiently and safely for the occupants of the home.
