Which of the following is covered by the National Electrical Code?
The correct answer is C: Electrical safety of the station. What is covered by the National Electrical Code is electrical safety of the station. The NEC covers electrical wiring, grounding, and safety requirements, not RF or modulation. For amateur radio operators, this is important for station electrical safety. Understanding this helps ensure compliance with electrical codes.
Exam Tip
National Electrical Code covers = electrical safety of station. Think 'N'EC = 'N'ational 'E'lectrical 'C'ode = 'E'lectrical 'S'afety. NEC covers electrical wiring, grounding, and safety requirements. Not bandwidth, not modulation, not RF exposure - just electrical safety.
Memory Aid
"National Electrical Code covers = electrical safety of station. Think 'N'EC = 'E'lectrical 'S'afety. NEC covers electrical wiring, grounding, and safety requirements. Not RF regulations - just electrical safety."
Real-World Application
The National Electrical Code: It covers electrical safety requirements - wiring, grounding, circuit protection, etc. It doesn't cover RF bandwidth, modulation, or RF exposure - those are FCC regulations. The NEC is about electrical safety of the station - ensuring safe electrical installation and operation. This is what the NEC covers.

Why Other Options Are Wrong
Option A: Incorrect. Acceptable bandwidth limits aren't covered by NEC - that's FCC regulations, not electrical code. Bandwidth isn't NEC.
Option B: Incorrect. Acceptable modulation limits aren't covered by NEC - that's FCC regulations, not electrical code. Modulation isn't NEC.
Option D: Incorrect. RF exposure limits aren't covered by NEC - that's FCC regulations, not electrical code. RF exposure isn't NEC.
