What is the reason for requiring proper strain relief for pendant cords?

Requiring proper strain relief for pendant cords is crucial primarily to prevent accidental pulling and damage to the connection. Strain relief mechanisms are designed to absorb tension and movement that might otherwise exert force on the connections or the cord itself. Without adequate strain relief, the stress from pulling or bending can lead to wear and tear, resulting in potential failure of the electrical connection, short circuits, or equipment malfunction. Ensuring that the cord maintains its integrity is vital for safety and operational reliability, as compromised connections can present significant hazards, including electrical shock or equipment fires.

While easier access for repairs, visibility in low light, and maintaining aesthetic appearance are considerations in various contexts, they do not address the immediate safety concern that strain relief aims to mitigate, which is the risk of accidental damage to the cord connections through excessive movement or tugging.
