True or False: Cable must be secured at every 4½ feet when fastened to studs.

The requirement to secure cable at every 4½ feet when it is fastened to studs is based on National Electrical Code (NEC) guidelines. This rule is in place to ensure safety and to minimize the risk of damage to the cables, which can occur if they are left unsecured. Securing the cable helps prevent it from being moved, pinched, or subject to abrasion. This regular fastening contributes significantly to maintaining the integrity of the electrical system in a building, reducing the chances of electrical hazards, such as short circuits or fire risks.

While there are certain exceptions or different requirements for specific types of cable or installations, the standard practice for most residential wiring involves securing the cable at this specified interval when installed in walls or ceilings. The frequency of fastening ensures that electrical cables remain in place and are protected from physical damage.
