Liquid tight flexible metal conduit (LFMC) must be securely fastened within what distance of each box or other conduit?

Liquid tight flexible metal conduit (LFMC) must be secured within 12 inches of each outlet box or junction box. This requirement ensures that the conduit maintains its integrity and is properly supported, preventing mechanical damage and allowing for safe electrical installations. This distance is specified to ensure that stress and strain on the conduit at the point where it connects to the box or other conduit do not cause damage over time. By securing the LFMC within this distance, it helps maintain compliance with established electrical codes and enhances the overall safety and reliability of the electrical system.
