How often must type MC metal-clad cables be secured?

Type MC metal-clad cables must be secured at intervals not exceeding 6 feet. This requirement is crucial for ensuring the stability and safety of the installation. Regular securing of the cables prevents movement that could cause abrasion or damage to the cable insulation, which in turn helps to reduce the risk of electrical hazards such as short circuits or fires.

Adhering to this requirement is part of the National Electrical Code (NEC) regulations that ensure proper handling and installation practices. The specified 6-foot interval strikes a balance between providing enough support to prevent physical stress on the cables while allowing for flexibility in routing and installation. Understanding and applying this standard is essential for practicing safe electrical installation methods and complying with legal regulations.
