True or False: Fluorescent luminaires with serviced ballast must have a disconnecting means.

The statement is true because according to the National Electrical Code (NEC), specifically in Article 410, luminaires that contain replaceable components such as ballasts require the provision of a disconnecting means. This is crucial for ensuring safety during maintenance or servicing. A disconnecting means allows for the electrical supply to be turned off, preventing accidental energization of the fixture when personnel are working on it. This practice is vital to protect workers from potential electric shock hazards and to ensure the safe handling of fluorescent luminaires during servicing.

Options that suggest false or conditional situations do not conform to the NEC's requirement for safety measures during the maintenance of electrical equipment. For installations that involve fluorescent luminaires with serviced ballasts, having a disconnecting means is always necessary, regardless of the location or type of installation.
