In which tables can class 2 power source voltage limitations and overcurrent protection requirements be found?

Class 2 power sources are governed by specific voltage limitations and overcurrent protection requirements that ensure safety and functionality in electrical installations. These particulars are outlined in the National Electrical Code (NEC) under guidelines that define what can be classified as Class 2 circuits, primarily found in Chapter 9 of the NEC.

The tables in Chapter 9 provide detailed information and standards regarding conductor sizes, voltage ratings, and overcurrent protection for Class 2 circuits. Specifically, Tables 11(a) and 11(b) establish the maximum allowable circuit voltage and specify the required overcurrent protection for Class 2 wiring systems. This is crucial for ensuring that the circuits remain within safe operational limits and are adequately protected against overload conditions.

In contrast, the other chapters and tables mentioned address different electrical concepts or standards that do not pertain directly to Class 2 circuits. Therefore, the information needed regarding Class 2 power source voltage limitations and overcurrent protection is comprehensively covered in Chapter 9, making it the correct reference for these requirements.
