What additional compliance must flexible cord and cord connections for electric discharge luminaires meet, according to WAC?

The requirement for flexible cord and cord connections for electric discharge luminaires to be of hard or extra hard usage is critical for ensuring safety and durability in various applications. Hard and extra hard usage cords are designed to withstand tough conditions including exposure to mechanical wear and environmental factors. This specification is important because electric discharge luminaires can be used in a variety of settings, which might subject the cord to more stresses than ordinary usage cords are designed to handle.

By utilizing hard or extra hard usage cords, you minimize the risk of insulation failure, overheating, and potential electrical hazards which could arise from inadequate cord strength. Such requirements ensure that the installation remains compliant with safety regulations and performs reliably over time, contributing to overall safety in electrical installations.

Other options, while they may pertain to specific scenarios, are not universally necessary for all installations involving discharge luminaires, reflecting the unique demands placed on cords in those applications.
