What is the main concern when identifying branch circuit conductors near components like ballasts?

The primary concern when identifying branch circuit conductors near components such as ballasts is overheating. Ballasts, which are commonly used in fluorescent lighting systems and other applications, can generate significant heat during operation. If branch circuit conductors are not properly rated for the current they carry or if they are in close proximity to components that emit heat, there is a risk that the conductors can overheat.

Overheating can lead to the degradation of the conductor insulation, create excess resistance within the circuit, and ultimately pose a fire hazard. In maintaining electrical safety and performance, it is crucial to ensure that conductors are appropriately sized, installed with adequate spacing, and properly ventilated to manage the heat generated by nearby components. This concern underscores the importance of adherence to electrical codes and standards, which guide the correct installation practices to prevent overheating and safeguard both equipment and life.
