Class 2 circuits defined by the NEC as the wiring between the load side of a class 2 limited or nonpower limited source and the connected equipment

• A. the supply side of a Class 2 source and the distribution panel
• B. the wiring between a Class 1 power source and lighting fixtures
• C. the load side of a class 2 limited or nonpower limited source and the connected equipment
• D. the wiring between the main service and subpanel

Answer: (C)

Class 2 circuits are defined by the wiring that runs from the output (the load side) of a Class 2 limited or nonpower‑limited source to the equipment it powers. In other words, the circuit consists of the conductors and connections that deliver the limited energy from the power source to the connected device. This keeps the energy level low and the wiring simple and safer for installing devices like low‑voltage sensors or CCTV cameras. The other scenarios describe parts of the power system that are not the Class 2 circuit itself: the wiring on the supply side or inside the main distribution path, or general power distribution between service equipment, which fall outside the Class 2 definition.
