What is a common feature expected of cable clamps in boxes?

Cable clamps in electrical boxes are primarily designed to securely hold conductors in place. This secure holding is essential to prevent any movement of the conductors, which could lead to damage, looseness in electrical connections, or even safety hazards such as electrical shorts or fire risks.

A well-secured conductor also helps to maintain the integrity of the electrical system and ensures that the installation complies with the National Electrical Code (NEC), which emphasizes safety and the reliability of electrical systems. This requirement helps to ensure that the installation is both safe and durable, minimizing the risk of unintended disconnections or interference that could arise from loosely secured conductors.

While other features may be beneficial, such as being inexpensive or allowing for adjustments, the foremost function of cable clamps is their ability to hold conductors firmly and safely.
