Specifically, the Board is aware that unlicensed individuals are currently replacing ballasts, believing that such conduct falls within the statutory exemption for repairing electrical equipment or apparatus. The replacement of ballasts, which are components of electric- discharge lamps that are used to provide the starting voltage or to stabilize the current in such lamps, however, fall outside the scope of ordinary servicing or repairing of electrical equipment contemplated by the Act. The replacement of ballasts is an inherently dangerous activity for persons not properly trained in electrical contracting because such activity requires the disconnection of live electrical wires. Ballast replacements performed by unlicensed persons have resulted in serious injuries and, in some instances death, to such persons in the past. Therefore, in order to ensure the health, safety and welfare of the general public, the Board is proposing the new rule in order to clarify that the replacement of ballasts is not included within the statutory exemption authorizing unlicensed individuals to test, service or repair electrical equipment or apparatus. Such work, therefore, must be performed by a licensed electrical contractor.
