The voltage across the condenser fan motor during operation is:

• A. 120 V
• B. 240 V
• C. 480 V
• D. 600 V

Answer: (B)

Condenser fan motors in typical residential units run off the higher voltage provided by the building’s split‑phase service, which is delivered across two hot conductors. The motor is wired between those two hot lines, so it experiences the full line-to-line voltage. That is the voltage you measure across the motor terminals while it’s operating. The other options would correspond to different, non-applicable cases: one hot-to-neutral voltage powers things like lights and outlets rather than a motor, and the much higher voltages are used in industrial three-phase systems, not standard residential condensers.
