A pendant box must be supported by a multiconductor cord or cable in a manner that protects the conductors against what?

A pendant box, often used for hanging light fixtures or similar applications, must be supported by a multiconductor cord or cable to ensure safe and reliable operation. The primary concern with this type of support is to protect the conductors against strain.

Strain can occur due to weight, movement, or tension on the cord or cable, which can lead to damage over time, such as conductor breakage or insulation failure. Proper support mechanisms are put in place to mitigate any strain on the conductors, ensuring that they remain intact and function properly without risk of electrical faults or hazards.

While flexing, heat, and moisture are all important considerations in electrical installations, the specific focus in this context is on how the support of the pendant box directly relates to the strain exerted on the conductors. Therefore, ensuring that the installation accommodates for strain effectively protects the integrity of the electrical system and promotes longevity and safety.
