*Question G0B06:
Which of the following is covered by the National Electrical Code?*  

*Correct Answer is  C: Electrical safety of the station*  

### AI Response: (may contain errors)  

The National Electrical Code (NEC) is a set of standards designed to ensure the safe installation of electrical wiring and equipment. Here's why the correct answer is "Electrical safety of the station":

1. **Correct Answer: C - Electrical safety of the station**
   - The NEC provides guidelines and requirements for electrical installations to prevent electrical hazards. This includes wiring, grounding, and other safety measures that are crucial for the safe operation of an amateur radio station.

2. **Why the Other Choices are Incorrect:**
   - **A: Acceptable bandwidth limits**
     - Bandwidth limits are regulated by the Federal Communications Commission (FCC) and are not covered by the NEC. These limits pertain to the frequency spectrum and how much of it a signal can occupy.
   - **B: Acceptable modulation limits**
     - Modulation limits are also regulated by the FCC. They define how signals can be modulated for transmission, ensuring efficient use of the spectrum and minimizing interference.
   - **D: RF exposure limits of the human body**
     - RF exposure limits are set by the FCC and other health organizations, such as the IEEE and ICNIRP. These limits are designed to protect humans from excessive radio frequency exposure, not covered by the NEC.

3. **Useful Rules of Thumb:**
   - When setting up an amateur radio station, always refer to the NEC for electrical safety guidelines, such as proper grounding and circuit protection.
   - For RF exposure and bandwidth/modulation limits, consult FCC regulations and guidelines.

Understanding the scope of the NEC helps ensure that your station is both safe and compliant with electrical safety standards.
